NVIDIA opens source code for real time character and robot movement model

NVIDIA released open source code and pre-trained files for a system called MotionBricks, which generates continuous movement for visual avatars and physical humanoid robots. According to the project repository published on GitHub, the software calculates smooth transitions between a character's current position and its target location thirty times every second.

Instead of requiring creators to manually animate every step or re-engineer code for different tasks, the tool uses modular building blocks for movement. This allows actions such as vaulting over obstacles, running, and sitting down to link together seamlessly without additional training. Because the system supports both computer graphics models and physical hardware such as the Unitree G1 robot, developers can use the same underlying framework across digital simulations and real machinery.

This release helps bridge the divide between computer animation and practical robotics by offering a unified control approach. However, it remains to be seen how reliably these calculated movements will hold up in real-world environments, where unexpected physical friction, mechanical delay, or uneven surfaces can easily disrupt balance.
