3D Kinematics Playground

A SO-101 follower arm loaded from its URDF and rendered client-side with WebGL. Move each joint with the sliders, click the ground to set a target for the damped-least-squares solver, or record a sequence of poses and play it back as an eased trajectory. Nothing here touches a server.

Drag to orbit. Scroll to zoom. Right-drag to pan. Click the ground to set an IK target, or type one into the target form. In the trajectory panel, Record arms keyframe capture and Play eases between the saved poses. Model: SO-101 from TheRobotStudio/SO-ARM100 (Apache-2.0), meshes converted to GLB with Draco compression.
