chess_bench
General chess manipulation demonstrations: a privileged scripted IK expert in NVIDIA Isaac
Lab (Arena) picks up any piece from the standard opening and carries it to a random central
square. Actions are the native DROID joint-position command (7 absolute arm joint targets +
binary gripper), so pi0.5/openpi/GR00T consume them directly. Each episode is labelled with its
own instruction (move the {color} {type} from {src} to {dst}); rollouts are kept
whether or not they succeed (per-episode success flag preserved in the source HDF5).
- Robot: Franka Panda + Robotiq 2F-85 (DROID platform); expert drives a DifferentialIKController (dls) into stiff PD joint-position control.
- Control / record rate: 15 Hz.
- Episodes: 269 (269 scored success by the privileged check).
