Good morning, Liam.

Hello.

Thank you very much for accepting to have this little chat.
Could you tell us something about you?

Sure. So my name is Liam Paull. I’m a professor at the University of Montreal in Quebec, Canada. I teach in the computer science Department, And I do research on robotics.

Ok and when was the first time you “came across” Duckietown?

Well, I’m actually one of the creators of Duckietown, So I didn’t come across it as much! The origin story of Duckietown is kind of interesting, But I probably forgot some of the details. It must have been about 2015. And myself, Andrea Censi, and a few others were interested to get more teaching experience. We were all postdocs or research scientists at MIT at the time. I guess we started brainstorming ideas, and then roughly around that time, I switched positions at MIT. I was previously a postdoc in John Leonard’s group working on marine robotics, and then I switched to become part of Danielle Lerous lab and lead an autonomous driving project. And so somehow the stars just aligned. That the right topic for this class that we would teach would be autonomous driving. Yeah, the Ducky thing is kind of a separate thing. Actually, Andrea had started this other thing that was making videos for people to publicize their work at a top robotics conference Called the international conference robotics automation, and somehow had the idea that every single video that was submitted should have a rubber Ducky in it. And this was for scale or something.
There was some kind of reason behind it I sort of forget. But anyway, so the branding kind of caught fire.
When we were building the class, we agreed the one constraint was that there should be duckies involved somehow, and the rest is kind of history!

What’s your relationship with Duckietown today? Like, do you use it in particular for some activities, your daily work or some project? Yeah, for sure. I guess I use it in a number of ways. Maybe the first way is that I teach a class every fall called autonomous vehicles, Where the Duckietown platform is the platform that we use for the experiments and labs in the class. So just like the original class, Every student gets a robot that they assemble, and then we learn about computer vision and autonomous driving and all the good stuff related to robotics. But I also use the platform for some amount of research. Also in my group, I believe that there’s a lot of interesting research directions that come from a kind of standardized, small scale, accessible autonomous driving platform like this. Recently, most of the work that we’ve been doing in terms of research has been about training agents in simulation and then deploying them in the real world. So this isa nice setup for that because we have a simulator that’s very easy, fast and lightweight to train in, and then we have the environment that’s also really accessible. So, yeah, so we’ve been doing some research on that front.
So would you recommend Duckieown to colleagues or students of yours? And if yes, why. Of course. I think that’s what’s nice. Going back to the original motivation behind building Duckietowng and some of the tenets: thee guiding principle for us was this idea that to learn robotics, you have to get your hands on a robot. And we are also very adamant that it should be that every student should have their own robot. With teams of robots or going into the lab and only being able to use the robot at certain hours. It’s something funny.
You don’t develop the same kind of personal relationship. It sounds weird, but it’s true. Like when you have your own thing that you’re working with every day, you have some kind of bond with that thing, and you develop some kind of love or hate or whatever the case may be depending on how things are going on that particular day. So I think that with this set up, we have a platform where we’ve scaled things down and made things cost effective, to be able to do that. We built an engaging, experimental platform where it’s totally, I think, reasonable for most University budgets to be able to get their hands on the hardware.

"I believe that there's a lot of interesting research directions that come from a standardized, small scale, accessible autonomous driving platform like Duckietown."

Liam Paull
The other big piece is the actual teaching materials that we’ve developed. And I think that we have some good stuff. It could be better. Some stuff could be better, but that’s where we also need the community to come in. I mean, if we have this standardized platform and lots of people start using it and building educational experiences around the platform, then the entire thing just starts to get better and better for everybody. And it just grows into a very nice thing where you can also pick and choose the pieces that you want to include for your particular class, and you can customize the experience of what your class is going to look like using all of the resources that are out there. Also, the other part that I’ve really tried to cultivate, this is sort of a new thing. When we ran the first class at MIT, it was really an isolated thing. But in the subsequent iterations of the class, like myself and others have been in different places around the world, whether it’s Matt Walter at TTIC or Jacopo and Andrea at ETH. So we tried to turn the class into this kind of global experience, where you feel like you’re part of something that’s bigger than just the class that you’re taking at the specific University. And I think students really like that. We’ve experimented with different models where people do projects with other students from other universities or even just feeling part of the global community. I think it’s a very fun and engaging. Students are so connected these days. They’re so plugged in. They like this aspect of feeling like there’s a bit more of a broad social aspect, too. So I think these are some of the elements that this platform project experience brings to the table that I don’t see replicated and too many other setups.

Anything else you would like to add about Duckietown and it’s uses?

I didn’t mention specifically about the MOOC. One of the core missions of this project from the onset has been that it’s accessible. Both in terms of hardware but also in terms of software. And part of what that means to us Is that no matter where you are, no matter who you are, you should be able to get the hardware and you should be able to use the educational resources to learn. And part of the motivation for that Was that we saw that while we were at MIT. When you’re at a place like MIT you are extremely privileged and if you come from a background of less privilege, you see the discrepancy. In some sense, it’s palpable. Part of that, I guess, was that we don’t even necessarily want it to be a prerequisite that students should be enrolled in universities in order to be able to address the platform. So we built this massive online open source course through edx, which is also an open source provider Where people can, regardless of their background or regardless of their situation, they can sign up for this thing, and it’s a creative set of materials that also have exercises to interact with the robot that anybody can do, Regardless of whether they’re at a University or not.
I think this is the next step for us in making the platform accessible to all, and we’re going to continue to run iterations of this thing. But I also think that this is an exciting objective that very much fits in the mission of what we’re trying to do with this project.

This was great thank you for your time!

Awesome. Great. Thank you for your time. Bye.

Learning Autonomy with Vincenzo Polizzi

Posted on | by Ivano Marocchi

ETHZ, Zurich, March 11, 2022: How Vincenzo discovered his true professional passion as a student using Duckietown.  

Learning Autonomy in practice with Vincenzo Polizzi

Vincenzo Polizzi studied robotics, systems and control at the Swiss Federal institute of Technology (ETH Zurich). Vincenzo shares below his experience with Duckietown. Starting off as a student, becoming a Teaching Assistant and onto how he uses Duckietown to power his own research as he moves from academia to industry.

Could you tell us something about yourself?

I’m Vincenzo Polizzi , I studied automation engineering at the Politecnico di Milano, and I currently study robotics, systems and control at the Swiss Federal Institute of Technology (ETH Zurich).

You use Duckietown. Could you tell us when you first came into contact with the project, and what attracted you to Duckietown?

Sure! I learned about Duckietown my first year during a master’s program at ETH, where there was a course called: “Autonomous mobility on demand, from car to fleet” where I saw these cars, these robots. And I asked myself “what is this thing?”. It seemed very interesting. The first thing that struck me was that it did not look theoretical, but clearly practical.

"It captures you with simplicity and then you stay for the complexity."

Vincenzo Polizzi

So the idea of a practical aspect interested you?

Yes, during the presentation, it was clear that the course was based on projects the student had to carry out, where one could practice what they had learned theoretically in other classes.
I come from a scientific high school, and I studied automation engineering in Milan. In both my study experiences, I was used to learning concepts theoretically. For example, in the control system for a plant you design on paper in university, you don’t really face the complexity of implementing it on a real object.

I have to say that I have always been very passionate about robotics and informatics. In fact, even in high school, I was building these little robots,I participated in the robotics competition Rome Cup held by Fondazione Mondo Digitale, and there were these robots that were similar in shape to those of Duckietown, but where the scientific content was completely different. So in Duckietown, I saw something similar to what I was doing in my free time. I wanted to see exactly how it was inside, and there I discovered a whole other world that is obviously much more scientific than what a normal high school student could imagine by themself. However, initially I was curious to see a course where one can practice all the knowledge they have gradually acquired. It is not just about writing an equation and finding a solution but making things work.

What is your relationship with Duckietown, how long have you been using it? How do you interact with the Duckietown ecosystem? How do you use it, what do you do with it?

These are interesting questions because I started as a student and then managed to see what’s behind Duckietown. I was attending the course Duckietown held at ETH in 2019. The class was limited to 30 students, I was really excited to be part of it. I met many excellent students there, some of whom I am still in touch with today.

When I started the course, I immediately told myself, “Duckietown is a great thing. If all universities used Duckietown, this would be a better world.” I liked the class a lot, then I also had the opportunity of being a TA. The TAship was an important step because I learned more than during the course. One thing is to live the experience as a student who has to take exams, complete various projects, etc. You need a deeper understanding to organize an activity. You have to take care of all the details and foresee the parts of the exercise that can be harder or simpler for the students. This experience helped me a lot. For example, I did an internship in Zurich where we had to develop a software infrastructure for a drone, and I found myself thinking, “wow this can be done with Duckietown, we can use the same technologies.” I noticed that even in the industry, often we see the use of the same technologies and tools that you can learn about thanks to Duckietown. Of course, maybe a company has its own customized tools, probably well optimized for its products. Perhaps it uses some other specific tool but let’s say you already know more or less what these tools are about. You know because in Duckietown, you have already seen how a robotics system should work and the pieces it is composed of. Duckietown has given me a huge boost with the internship and my Master’s thesis at NASA JPL. Consider that my thesis was on a system of multi drones, so I used, for example, Docker as a tool to simulate the different agents. With Duckietown, I acquired technical knowledge that I used in many other projects, including work.

Do you still use it today?

The last project I did with Duckietown is DuckVision. I know we could have thought of a better name. With one of my Duckietowner friends, Trevor Phillips, we enhanced the Duckiebot perception pipeline with another camera, a stereocamera made by Luxonis and Open CV called OAKD (OpenCV AI Kit with depth). This sensor is not just a simple camera, but it also mounts a VPU, Visual Processing Unit. Namely, it can analyze and make inferences on the images that the camera acquires onboard. It can perform object detection and tracking, gesture recognition, semantic segmentation, etc. There are plenty of models freely available online that can run on the OAK-D. We have integrated this sensor in the Duckietown ecosystem, using a similar approach used in the MOOC “Self-Driving Cars with Duckietown”, we created a small series of tutorials where you can just plug the camera on the robot, run our Docker container and have fun! With this project, we passed the first phase of the OpenCV AI Competition 2021. The idea behind the project was to increase the Duckiebot understanding of the environment, by using the depth information, the robot can have a better representation of its surroundings and so, for example, a better knowledge of its position. Also, in our opinion, the OAK-D in Duckietown can boost the research in autonomous vehicles and perception.
I would like to add something about the use of Duckietown, I have seen this project both as a student and from behind the scenes and I really understood that by using this platform you really learn a lot of things that are useful not only in the academic field but can also be very useful in the working environment with the practical knowledge that is often difficult to acquire during school. And in this regard I thought then given my history, I am Sicilian but I studied in Milan and then I went to Zurich, I asked myself what can I bring as a contribution of my travels, so I thought about using Duckietown in some universities here in Sicily in the universities of Palermo and Messina. And also, at the Polytechnic of Milan, for example, they have already begun to use it and have participated in the AIDO and have also placed well, they ended up among the finalists, so there is a lot of interest in this project.

Did you receive a positive response every time you proposed Duckietown?

Yes, and then there is a huge enthusiasm on the part of the students. I spoke with student associations first, then with the professors etc. but when the students see Duckietown for the first time, they are always really enthusiastic about using it.

"There is something that captures you in some way, and then just opens up a world when you start to actually see how all the systems are implemented. This is the nice thing in my opinion, you can decide the level of complexity you want to achieve."

Vincenzo Polizzi

The duck was a great idea!

Absolutely right! The duck was a great idea, yes. I like contrasts, you see a super simple friendly thing that hides a state-of-the-art robotics platform. Even in the students I saw this reaction, because the duck is the first thing you see, it looks like a game, something to play with, this is the first impact, then when you start you get curious. It captures you with simplicity and then you stay for the complexity.

Would you suggest Duckietown to friends and colleagues?

Sure! There is something that captures you and opens up a world when you start to see how all the systems are implemented. This is the nice thing in my opinion, you can decide the level of complexity you want to achieve. It’s a platform that looks like something to play with, a game or something, but in reality there is a huge potential, in terms of knowledge that everyone can acquire, it’s something that you can not easily find elsewhere. I also think it offers great support, such as educational material, exercises that are of high quality. You can learn a lot of different aspects of robotics, in my opinion. You can do control, you can do the machine learning part, perception . There’s really a world to explore. You can see everything there is about robotics. But you can also just focus on one aspect that maybe you’re more passionate about. So yes, I would recommend it because you can learn a lot, and as a student myself I would recommend it to my fellow colleagues.

The AI-DO serves to benchmark the state of the art of artificial intelligence in autonomous driving by providing standardized simulation and hardware environments for tasks related to multi-sensory perception and embodied AI.

Duckietown traditionally hosts AI-DO competitions biannually, with finals events held at machine learning and robotics conferences such as the International Conference on Robotics and Automation (ICRA) and the Neural Information Processing Systems (NeurIPS). 

AI-DO 6 will be in conjunction with NeurIPS 2021 and have three leagues: urban driving, advanced perception, and racing. The winter champions will be announced during NeurIPS 2021, on December 10, 2021!

Urban driving league
Advanced perception and racing leagues

Urban driving league

The urban driving league uses the Duckietown platform and presents several challenges, each of increasing complexity.

The goal in each challenge is to develop a robotic agent for driving Duckiebots “well”. Baseline implementations are provided to test different approaches. There are no constraints on how your agents are designed.

Each challenge adds a layer of complexity: intersections, other vehicles, pedestrians, etc. You can check out the existing challenges on the Duckietown challenges server.

AI-DO 2021 features four challenges: lane following (LF), lane following with intersections (LFI), lane following with vehicles (LFV) and lane following with vehicles and intersections, multi-body, with full information (LFVI-multi-full).

All challenges have a simulation and hardware component (🚙,💻), except for LFVI-multi-full, which is simulation (💻) only.

The first phase (until Nov. 7) is a practice one. Results do not count towards leaderboards.

The second phase (Nov. 8-30) is the live competition and results count towards official leaderboards. 

Selected submissions (that perform well enough in simulation) will be evaluated on hardware in Autolabs. The submissions scoring best in Autolabs will access the finals.

During the finals (Dec. 1-8) one additional submission is possible for each finalist, per challenge.

Winners (top 3) of the resulting leaderboard will be declared AI-DO 2021 winter champions and celebrated live during NeurIPS 2021. We require champions to submit a short video (2 mins) introducing themselves and describing their submission.

Winners are invited to join (not mandatory) the NeurIPS event, on December 10th, 2021, starting at 11.25 GMT (Zoom link will follow).

The challenges

Lane following 🚙 💻

LF – The most traditional of AI-DO challenges: have a Duckiebot navigate a road loop without intersection, pedestrians (duckies) nor other vehicles. The objective is to travel the longest path in a given time while staying in the lane, i.e., not committing driving infractions.

Current AI-DO leaderboards: LF-sim-validation, LF-sim-testing.

Previous AI-DO leaderboards: sim-validation, sim-testing, real-validation.

Get the LF hardware kit

Lane following with intersections 🚙 💻

LFI – This challenge builds upon LF by increasing the complexity of the road network, now featuring 3 and/or 4-way intersections, defined according to the Duckietown appearance specifications. Traffic lights will not be present on the map. The objective is to drive the longest distance while not breaking the rules of the road, now more complex due to the presence of traffic signs.

Current AI-DO leaderboards: LFI-sim-validation, LFI-sim-testing.

Previous AI-DO leaderboards: sim-validation, sim-testing.

Lane following with vehicles 🚙 💻

LFV – In this traditional AI-DO challenge, contestants seek to travel the longest path in a city without intersections nor pedestrians, but with other vehicles on the road. Non-playing vehicles (i.e., not running the user’s submitted agent) can be in the same and/or opposite lanes and have variable speed.

Current AI-DO leaderboards: LFV-sim-validation, LFV-sim-testing.

Previous AI-DO leaderboards: (LFV-multi variant): sim-validation, sim-testing, real-validation.

Enroll for free on edX

In this course you will learn, hands-on, introductory elements of:

  • computer vision
  • robot operations 
  • ROS, Docker, Python, Ubuntu
  • autonomous behaviors
  • modelling and control
  • localization
  • planning
  • object detection and avoidance
  • reinforcement learning.

Robert Moni’s experience after winning AI-DO 5

Posted on | by Liuxin

An interview with Robert Moni

Robert is a Ph. D. student at the Budapest University of Technology and Economics.

His work focuses on deep learning and he has (co)authored papers on reinforcement learning (RL), imitation learning (IL), and sim-to-real learning using for autonomous vehicles using Duckietown.

Robert and his team won the LFV_multi hardware challenge of the 2020 AI Driving Olympics.

Today, Robert shares some of his thoughts with us!

What brought you to work on AVs?

I started my journey in the world of AV’s in 2016 when I was hired at the automotive supplier company “Continental” in Romania. In 2018 I moved to Budapest, Hungary, to join Continental’s Deep Learning Competence Center where we develop novel perception methods for AVs.

In 2019, with the support of the company, I started my Ph.D. at Budapest University of Technology and Economics on the topic “Deep Reinforcement Learning in Complex environments”.

At this time, I crossed paths with the Duckietown environment. Continental bought 12 Duckiebots and supplementary materials to build our own Duckietown environment in a lab at the university.

Tell us about you and your team

At the beginning of my Ph. D. and with the arrival of the Duckietown materials we established the “PIA” (Professional Intelligence for Automotive) project with the aim to provide education and mentorship for undergrad and master students in the field on Machine Learning and AV.

In each semester since 2019 February I managed a team of 4-6 people developing their own solutions for AI-DO challenges. I wrote a short blogpost presenting my team and our solutions submitted to AI-DO 5.

"With the arrival of the Duckietown material we established the PIA project with the aim to provide education and mentorship for undergrad and master students in the field on Machine Learning and autonomous vehicles (AV)."

Robert Moni

What approach did you choose for AI-DO, and why?

I started to tackle the AI-DO challenges applying deep reinforcement learning (DRL) for driver policy learning and state representation learning (SRL) for sim2real transfer.

The reason for my chosen approach is my Ph. D. topic, and I plan to develop and test my hypotheses in the Duckietown environment.

What are the hardest challenges that you faced in the competition?

In the beginning, there was a simple agent training task that caused some headaches: finding a working DRL method, composing a good reward function, preprocessing the observations to reduce the search space, and fine-tuning all the parameters. All these were challenges, but well-known ones in the field.

One unexpected challenge was the continuous updates of the gym-duckietown environment. While we are thrilled that the environment gets improved by the Duckietown team, we faced occasional breakdowns in our methods when applying them to the newest releases, which caused some frustration.

The biggest headache was caused by the different setups in the training and evaluation environments: in the evaluation environment, the images are dimmed while during training they are clear. Furthermore, the real world is full of nuisances – for example lags introduced by WiFi communication, which causes different outcomes in the real environment. This challenge can be mitigated to some degree with the algorithms running directly on the Duckiebot’s hardware, and by using a more powerful onboard computer, e.g., the Jetson Nano 2GB development board.

Are you satisfied with the final outcome?

I am satisfied with the achievements of my team, which kept the resolve throughout the technical challenges faced.

I’m sure we would’ve done even better in the real-world challenge if we had seen our submission running earlier in the Autolab, so we could have adjusted our algorithms. We are going to work to bring one to our University in the next future.

What are you going to change next time?

I believe the AI-DO competition as well as the Duckietown platform would improve through more powerful hardware. I hope to see Duckiebots (DB19)  upgraded to support the new Jetson Nano hardware!

(Since the date of the interview, Duckiebots model DB21 supports Jetson Nano boards)

AI-DO 5 competition Update

Posted on | by Andrea Censi

AI-DO 5 Update

AI-DO 5 is in full swing and we want to bring you some updates: better graphics, more maps, faster and more reliable backend and an improved GUI to submit to challenges! 

Challenges visualization

We updated the visualization. Now the evaluation produces videos with your name and evaluation number (as below).

Challenges updates

We fixed some of the bugs in the simulator regarding the visualization (“phantom robots” popping in and out). 

We updated the maps in the challenges to have more variety in the road network; we put more grass and trees to make the maps more joyful!

We have updated the maps with more trees and grass

Faster and more reliable backend

The server was getting slow given the number of submissions, and sometime the service was unavailable. We have revamped the server code and added some backend capacity to be more fault-tolerant. It is now much faster!

Thanks so much to the participants that helped us debug this problem!

We overhauled the server code to make it much faster!

More evaluators

We brought online many more CPU and GPU evaluators. We now encourage you to submit more often as we have a lot more capacity.

We have many more evaluators now!

Submit to testing challenges

We also remind you that the challenges on the front page are the validation challenges, in which everybody can see the output. However what counts for winning are the testing challenges!  

To do that you can use dts challenges submit with the –challenges option

Or, you can use a new way using the website that we just implemented, described below.

Submitting to other challenges

Step 1: Go to your user page, by clicking “login” and then going to “My Submissions”.

Step 2: In this page you will find your submissions grouped by “component”. 

Click the component icon as in the figure.

Step 3: The page will contain some buttons that allow you to submit to other challenges that you didn’t submit to yet.

Compete in the 5th AI Driving Olympics (AI-DO)

The 5th edition of the Artificial Intelligence Driving Olympics (AI-DO 5) has officially started!

The AI-DO serves to benchmark the state of the art of artificial intelligence in autonomous driving by providing standardized simulation and hardware environments for tasks related to multi-sensory perception and embodied AI.

Duckietown hosts AI-DO competitions biannually, with finals events held at machine learning and robotics conferences such as the International Conference on Robotics and Automation (ICRA) and the Neural Information Processing Systems (NeurIPS). 

 The AI-DO 5 will be in conjunction with NeurIPS 2020 and have two leagues: Urban Driving and Advanced Perception. 

Urban driving league challenges

This year’s Urban League includes a traditional AI-DO challenge (LF) and introduces two new ones (LFP, LFVM).

Lane Following (LF)

Get the LF kit

The most traditional of AI-DO challenges: have a Duckiebot navigate a road loop without intersection, pedestrians (duckies) or other vehicles. The objective is traveling the longest path in a given time while staying in the lane.

Lane following with Pedestrian (LFP)

Get the LFP kit

The LFP challenge is new to AI-DO. It builds upon LF by introducing static obstacles (duckies) on the road. The objectives are the same as for lane following, but do not hit the duckies! 

Lane Following with Vehicles, multi-body (LFVM)

Get the LFVM kit

In this traditional AI-DO challenge, contestants seek to travel the longest path in a city without intersections nor pedestrians, but with other vehicles on the road. Except this year there’s a twist. In this year’s novel multi-body variant, all vehicles on the road are controlled by the submission.

Getting started: the webinars

We offer a short webinar series to guide contestants through the steps for participating: from running our baselines in simulation as well as deploying them on hardware. All webinars are 9 am EST and free!

Synch Webinar Calendar

Advanced sensing league challenges

Previous AI-DO editions featured: detection, tracking and prediction challenges around the nuScenes dataset.

For the 5th iteration of AI-DO we have a brand new lidar segmentation challenge.

The challenge is based on the recently released lidar segmentation annotations for nuScenes and features an astonishing 1,400,000,000 lidar points annotated with one of 32 labels.

We hope that this new benchmark will help to push the boundaries in lidar segmentation. Please see https://www.nuscenes.org/lidar-segmentation for more details.

Furthermore, due to popular demand, we will organize the 3rd iteration of the nuScenes 3d detection challenge. Please see https://www.nuscenes.org/object-detection for more details.

AI-DO 5 Finals event

The AI-DO finals will be streamed LIVE during 2020 edition of the Neural Information Processing Systems (NeurIPS 2020) conference in December.

IROS2020: Watch The Workshop on Benchmarking Progress in Autonomous Driving

Posted on | by Ivano Marocchi

What a start for IROS 2020 with the "Benchmarking Progress in Autonomous Driving" workshop!

The 2020 edition of the International Conference on Intelligent Robots and Systems (IROS) started great with the workshop on “Benchmarking Progress in Autonomous Driving”.

The workshop was held virtually on October 25th, 2020, using an engaging and concise format of a sequence of four 1.5-hour moderated round-table discussions (including an introduction) centered around 4 themes.

The discussions on the methods by which progress in autonomous driving is evaluated, benchmarked, and verified were exciting. Many thanks to all the panelists and the organizers!  

Here are the videos of the various sessions.
