Claude recreates a real desk in MuJoCo so an Astra robot arm can paint with variable brush strokes
DJiafei · x · 2026-10-12
Inspired by the Astra-Robotics trend, Yejin Kim had Claude recreate her real painting setup inside MuJoCo, then let an Astra robot arm paint in simulation. The system even planned strokes with a flat brush, enabling lines of varying width — impressing her enough to plan a transfer to the real robot next. A photo shows the real desktop arm with a paint palette.
