Physical AI: Teach a Robot Arm with LeRobot
Teach a robot arm by showing it, not by programming points: imitation learning, LeRobot and its datasets on the Hugging Face Hub, PushT and ALOHA in simulation, ACT and diffusion policies, the SO-101 arm, teleoperation and recording, training and honest evaluation, SmolVLA and vision-language-action models, Isaac Sim and sim-to-real, and the safety rules that keep learned control out of safety functions.

What you will learn
Explain how a learned policy differs from a taught-point robot program; load and inspect LeRobot datasets from the Hub; explain behaviour cloning, distribution shift and action chunking; evaluate a pretrained policy in the PushT simulator and train ACT on a simulated task; choose between ACT, diffusion and SmolVLA for a task and GPU; assemble, set up and calibrate an SO-101, teleoperate it and record demonstrations; train, deploy and evaluate a policy with an honest success rate; describe sim-to-real transfer and domain randomisation; and write the risk assessment that keeps a learned policy away from safety functions.
- Explain how a learned policy differs from a taught-point robot program, and where each belongs
- Load LeRobot datasets from the Hugging Face Hub and read their observations and actions
- Explain behaviour cloning, compounding error and why action chunking and diffusion help
- Evaluate a pretrained policy in the PushT simulator and train ACT on a simulated ALOHA task, with no hardware
- Choose between ACT, diffusion and SmolVLA for a task, a GPU and a number of demonstrations
- Set up, calibrate and teleoperate an SO-101 arm and record clean demonstrations (optional hardware path)
- Train, deploy and evaluate a policy with a written protocol and an honest 95 percent interval
- Explain sim-to-real transfer and domain randomisation, and keep learned control out of safety functions under ISO 10218:2025
The course project · about 16 hours
Train and honestly evaluate a learned policy on PushT, with an optional SO-101 pick-and-place
Evaluate a pretrained diffusion policy on the PushT simulator as a baseline, train your own diffusion and ACT policies on the same data within a fixed GPU budget, evaluate each on 100 episodes with a written protocol, report success rates with 95 percent intervals, and write a recommendation that says only what the numbers support. Optionally repeat the evaluation on an SO-101 pick-and-place.
Sample document pack, 5 documents, filled in for the scenario
- PlanStudy plan: learned policies in simulation before a bench trial
- ProcedureEvaluation procedure for learned policies on PushT
- Test reportPushT evaluation of four policies
- Risk registerBench risk register for the optional SO-101 trial
- ReportRecommendation on learned policies for the kitting enquiry

A shareable EDWartens certificate
Finish every module and pass the final assessment, and the optional EDWartens certificate is yours. It carries a unique verification code on a public page anyone can check, so it stands up when a recruiter looks it up. See it below.
The course itself stays free whether or not you ever buy one.
Stuck? Ask a practising engineer
A free course usually means a comment section and hope. This one does not. Every module has an Ask-your-trainer panel that reaches the same engineers who teach our paid programme: people who commission panels for a living, not moderators.

Reviews here are written only by learners who have finished every module of Physical AI: Teach a Robot Arm with LeRobot, and they are published exactly as written. Finish the course and yours will be the first.
Common questions
Who is this physical AI and LeRobot course for?
It is for robotics, mechatronics and automation engineers and engineering students who want to move from programming robots point by point to teaching them from demonstrations. Robot programmers from FANUC, ABB, KUKA or Universal Robots backgrounds, and ROS 2 users, will find it a natural next step.
Do I need a robot arm to take the course?
No. Every module has a simulation-only path: the PushT and ALOHA simulators run on a free Google Colab GPU, and real-robot datasets, including SO-101 ones, are on the Hugging Face Hub to train on. The SO-101 modules are optional and show what to do if you buy or build an arm later.
What do I need to know first?
You should be able to run a Python notebook and follow a command line. The course explains the machine learning it uses. If Python is new, take Python for AI and Engineering Data first; for classical robot software, ROS 2 Robot Programming with Python complements this course.
Which software does it use?
LeRobot, Hugging Face's open-source robot learning library (version 0.6 line in October 2026, Python 3.12 or later), with PyTorch, Google Colab and the Hugging Face Hub. Isaac Sim appears in one optional module and needs an RTX GPU. LeRobot changes quickly, so the notes give the current commands and tell you to check the release notes.
Is the course free to learn?
Yes. Every module, the notes, the worked problems, the project and the final assessment are free, and all the software used is free. The certificate is optional.
How long does the Physical AI: Teach a Robot Arm with LeRobot course take?
About 17 to 18 hours of video, notes and practice at your own pace, of which about 10.5 hours is video. The optional PushT project takes about 16 hours more, most of it waiting for training runs.
Is a learned policy safe to use on a factory robot?
Only for task decisions, inside the robot's rated safety configuration and a proper risk assessment. A learned policy is never allowed to be a safety function. The safety module covers ISO 10218-1 and -2 (2025 editions), why protective stops and speed limits must be rated hardware, and how to run a first test safely.
What certificate does the Physical AI: Teach a Robot Arm with LeRobot course give?
An EDWartens certificate of completion, issued when you finish the modules and pass the 15-question final at 60 percent, with a number anyone can verify on our site. It is not a certification from Hugging Face, NVIDIA or any robot maker, none of whom is affiliated with EDWartens.
Is the Physical AI: Teach a Robot Arm with LeRobot course free in India, and what does the certificate cost?
Yes. Learning costs ₹0 in India: every module, the written notes, the practice tasks and the final assessment, with no card and no trial period. The only paid item is the optional EDWartens Certificate of Completion, ₹559 including GST for this intermediate course, paid in rupees through Razorpay, and only if you want it after passing the final assessment.
Is there classroom robotics training in India as well?
Yes. EDWartens India runs the Automation Engineer Program (AEP), a classroom programme at its Electronic City centre in Bangalore with hands-on PLC, SCADA, HMI and drives hardware. This free course is separate and fully online; it is a good way to try the subject before deciding on classroom training. Details are at edwartens.co.in/courses/aep.
