A Python research codebase accompanying the paper 'Learning Agile Robotic Locomotion Skills by Imitating Animals'. It provides a Gym environment for training a simulated quadruped robot to imitate reference motion capture clips, plus MPC-based locomotion for the real A1 robot and PyBullet.

Use cases

• train a simulated quadruped robot to imitate animal motion capture
• learn agile locomotion policies with reinforcement learning
• run model predictive control locomotion on a Unitree A1 robot
• test pretrained quadruped locomotion policies in PyBullet
• reproduce results from the motion imitation paper

When to choose

• you need a ready-made Gym environment for quadruped motion imitation research
• you want pretrained policies and reference motion clips to experiment with
• you are reproducing or extending the paper's locomotion results

When to avoid

• you need a production robotics framework rather than research code
• you work with bipeds or non-quadruped robots without adaptation
• you need long-term support or frequent updates
