THE WORKBENCH / 01—05

Things I’m
working on.

Robots that learn. Tools that feel personal.
And experiments that start with “what if?”

YAM Decoupled IK

Simulation prototype

Adapted a decoupled inverse-kinematics solver to the I2RT YAM arm in MuJoCo, with an interactive target-tracking demo and headless checks.

  • Python
  • MuJoCo
  • Inverse kinematics

A port of the solver from Dream Machines Robotics’ vr-teleop-kit.
