New RL frameworks bridge sim-to-real gap for quadruped locomotion · 2 sources tracked

By PulseAugur Editorial · [2 sources] ·

Researchers have developed new reinforcement learning (RL) frameworks for quadrupedal locomotion, addressing the sim-to-real gap. The first approach, utilizing NVIDIA's Isaac Sim and Isaac Lab, achieves zero-shot sim-to-real transfer for whole-body control on a Unitree Go1, demonstrating robust recovery from disturbances and achieving linear velocities of 2.0 m/s. The second framework focuses on torque-driven RL for heavier quadrupeds, enabling them to traverse rough terrain and track desired velocities without explicit velocity observation, with simulation results on a Unitree B1 reaching 3.5 m/s.
