FAQPage Schema

How do I train a reinforcement learning locomotion policy for Unitree G1 in Isaac Sim?▼

To train a Unitree G1 locomotion policy in Isaac Sim, initialize the task in Isaac Lab and run a PPO walk-through to configure the environment, set observation and action spaces, and begin the training pipeline.

What is sim-to-real transfer and how does domain randomization work for robotics RL?▼

Sim-to-real transfer deploys policies trained in simulation to physical robots; domain randomization varies simulation physics, dynamics, and visuals during RL training to ensure the learned locomotion policy generalizes to real-world conditions.

Can I use SAC or TD3 instead of PPO for humanoid robot locomotion in Isaac Lab?▼

Yes, Isaac Lab supports SAC and TD3 workflows alongside PPO for humanoid robot locomotion; this guidance covers framework-aligned best practices for configuring these algorithms, observation spaces, and evaluation strategies across all three.

What's the best way to design reward shaping and curriculum learning for RL locomotion policies?▼

The best way to design reward shaping and curriculum learning for RL locomotion policies is to systematically structure environment rewards and progressively increase task difficulty, guiding the robot toward stable walking behaviors during training.

Does Isaac Sim require specific environment setup or observation space definitions to start RL training?▼

Yes, Isaac Sim requires defining observation and action spaces, configuring the RL environment, and setting up domain randomizations before initializing PPO, SAC, or TD3 training pipelines for the Unitree G1 humanoid robot.

Why does my RL policy fail during sim-to-real deployment on a humanoid robot?▼

RL policies often fail during sim-to-real deployment due to insufficient domain randomization, poorly shaped rewards, or observation space mismatches; addressing these environment design factors and deployment considerations improves transfer to the physical Unitree G1.
