Physical Simulation
MuJoCo + PyTorch
Move from scripted robot control to imitation learning, vision-language-action policies, PPO, and cross-domain reinforcement learning.
Goals
- Control robosuite environments and design Gymnasium rewards
- Collect expert trajectories and train behavior cloning policies
- Fine-tune SmolVLA on a LeRobot dataset
- Train PPO locomotion and study cross-domain policy transfer
Simulation and Imitation Learning
What this section covers
Build the environment and learn policies from demonstrations.
MT01 — Robosuite Introduction
Explore observations, actions, and random rollouts in a Panda Lift task.
MT02 — Controllers and Cameras
Script a reach-grasp-lift sequence and inspect visual observations.
MT03 — Gymnasium and Reward
Wrap a robot task as Gymnasium and design a dense reward.
MT04 — Behavior Cloning
Collect expert data and train a policy to imitate it.
MT05 — SmolVLA Fine-tuning
Fine-tune a vision-language-action model for manipulation.
Reinforcement Learning
What this section covers
Train and transfer policies across robot embodiments and tasks.
MT06 — PPO
Train an end-to-end PPO locomotion policy.
MT07 — Cross-Domain RL
Transfer knowledge across morphology and task changes.
