IKPy is a pure-Python inverse kinematics library that computes IK for arbitrary kinematic chains defined via URDF, MJCF, DH parameters, or custom representations. It supports position/orientation targets, multiple joint types, an optional JAX backend, and plotting of chains without a real robot.

Use cases

compute inverse kinematics for a robot arm from a URDF file
solve IK for end-effector position and orientation
import and analyze kinematic chains from URDF or MJCF files
test IK algorithms by plotting chains without a simulator
speed up IK solving with a JAX autodiff backend
track end-effector trajectories with warm-started IK

When to choose

you need a pure-Python, easy-to-install IK solver with no compilation
your robot model is described in URDF or MJCF
you want to prototype IK on arbitrary chains with plotting support

When to avoid

you need real-time control at very high frequencies where C++ solvers are required
you need dynamics, collision detection, or full physics simulation rather than kinematics
