Newton simulates the rigid and soft-body dynamics, contact, friction, and actuator and sensor modeling that robot learning depends on, letting multi-body systems acquire and validate behavior in virtual environments before deployment. The engine builds on NVIDIA Warp for GPU acceleration and composes robot and environment descriptions through OpenUSD.
Stewarded by the Linux Foundation and developed by NVIDIA with Google DeepMind and Disney Research, Newton ships as an open-source, differentiable core with pluggable solvers, including the GPU-optimized MuJoCo Warp, and integrates with robot-learning frameworks such as NVIDIA Isaac Lab.
