cuRobo is a CUDA accelerated library containing a suite of robotics algorithms that run significantly faster than existing implementations leveraging parallel compute. cuRobo currently provides the following algorithms: (1) forward and inverse kinematics, (2) collision checking between robot and world, with the world represented as Cuboids, Meshes, and Depth images, (3) numerical optimization with gradient descent, L-BFGS, and MPPI, (4) geometric planning, (5) trajectory optimization, (6) motion generation that combines inverse kinematics, geometric planning, and trajectory optimization to generate global motions within 30ms.

cuRobo generates motions for a UR10 within 100ms on a NVIDIA Jetson Orin.

cuRobo performs trajectory optimization across many seeds in parallel to find a solution. cuRobo’s trajectory optimization penalizes jerk and accelerations, encouraging smoother and shorter trajectories.

cuRobo leverages nvblox for collision avoidance with obstacles from a Depth camera.

cuRobo can constrain different axes and allow for planning in the remaining axes leveraging trajectory optimization.
