Open-Source Framework Enables Deployable Quadruped Locomotion via Differentiable Simulation

Researchers have developed Open-DiffLoco, an open-source framework for training quadruped locomotion policies using differentiable simulation. This framework enables the transfer of trained policies to real-world hardware, such as the Unitree Go2, without requiring complex reward engineering or privileged observations. The system demonstrated robust performance, tracking velocity commands with low error and achieving speeds over 1 m/s, even on uneven terrain and under physical disturbances. Training is efficient, requiring minimal GPU memory and completing in under an hour, with an algorithmic extension called Jacobian-Augmented Value Estimation (JAVE) proposed to enhance early policy-gradient training.
