Projects 2h robot dog simulation
I simulated this robot dog inside a training platform I built on top of the MuJoCo physics simulator. I built a specialized reinforcement learning trainer with** motion imitation (style reference motions)**: the dog learns to copy a keyframed trot while still balancing on its own, which makes the gait way smoother than plain RL. The joints are limited by realistic hobby servo models (torque, speed curve, backlash, latency), not infinite-strength motors. It trained on my MacBook Air’s CPU for 2 hours (no GPU) and learned multi-directional control (I can drive it with WASD) and balance.
