NVIDIA introduces a tool for transferring human motion to robots

Dataist Dataist

NVIDIA has released the open-source SOMA Retargeter v0.2, a tool that adapts human movements to the proportions and joints of humanoid robots. It takes animation on a SOMA skeleton, calculates robot poses, and saves trajectories as CSV files for training control systems. The release includes examples and configurations for five robots: Unitree G1, Unitree H2, Booster T1, AgiBot X2 Ultra, and AgiBot A3T3. Movements can come from motion-capture recordings, be reconstructed from video, or be generated from text and pose constraints.

Figure 1. The retargeting pipeline converts SOMA BVH motion into robot joint trajectories through scaling, inverse kinematics, and post-processing. Across many clips, the resulting animations can form a motion library for downstream reference preparation and policy training.

Figure 3. The source motion is a one-handed wave, but an unaligned reference pose makes Booster T1 hold both arms outward (left). After aligning the robot’s reference pose with the SOMA human reference, one hand waves beside its head while the other arm rests at its side (right). Both panels use the same input motion and IK settings, isolating the effect of reference-pose alignment.
