Robot arm & inverse kinematics (3D)

About this app

A robot arm with three joints: in forward mode you set the angles and the hand follows; in inverse mode you drag a target and the IK computes the angles — with two, one or no solution at all. Compare PTP and LIN motion on a glue seam, an overhead path and a stretch: the straight line in space turns curved in joint space, and near singularities the joint speed shoots up.
