This release is a pre-release and may not be stable for production use.
RoboKit is a high-performance, general-purpose toolkit for versatile robotic tasks. It scales from one problem to thousands in parallel. It provides a library of cost terms and optimizers that compose freely. Built-in tasks such as IK, motion planning, and retargeting are validated on real robots.
Thousands of robots solving in parallel.
Benchmarks
Bars are wall-clock time on the same task, baseline normalized to full width. Check the paper for benchmark details.
Optimization with Simulation
 Pen Spinning A Sharpa hand spins a pen in its fingers. |
 Cube Rotation A LEAP hand turns a cube to random goals. |
 Notebook Opening Two XHands open a hinged ARCTIC notebook. |
 Box Carrying A G1 lifts and carries a box. |
 Climbing A G1 climbs a box on hands and knees. |
 Jumping A Go2 lands four 40 cm jumps on target footholds. |
Optimization with Analytic Objectives
 IK Multi-link targets, fixed or floating base. |
 Motion Planning Collision-free trajectories, offline or online. |
 Hand-Eye Calibration Camera pose from rendered robot masks. |
 Humanoid Retargeting Human motion capture to a humanoid. |
 Hand Retargeting Human hand motion to a robot hand. |
 Grasp Optimization Force-closure grasps for any hand or body. |
How it works
| Component | Role | Read more |
|---|---|---|
| Robot | Load URDF or MJCF models and compute batched, differentiable kinematics. | Robot |
| Objectives | Cost terms that define a task: pose matching, collision, limits, contacts. | Terms |
| Optimizers | Sampling and gradient methods that minimize the objectives in parallel. | Optimization |
| Acceleration | Fast geometry and rendering for contact-rich and calibration tasks. | Geometry |
| Distillation | Train policies on solver outputs for even faster inference. |
Installation
Requires Python 3.8 or newer:
uv add robokit # or: pip install robokit
PyTorch is optional. See Installation for source installs and extras.
