oku006/bussing-pi05-droid via branch pi05-joint-velocity of sombit888/robot_evalsoku006/bussing-whiteboard-act via branch whiteboard-joint-velocity⚠️ This is a reference baseline, NOT the INSAIT whiteboard policy. It is LeRobot's off-the-shelf ACT implementation, included only as supporting evidence for comparison. The whiteboard policy is a different architecture: frozen swappable ViT encoder (DINOv2 / SigLIP / JEPA, 86.6M), 7-layer decoder, optional language conditioning, 142.3M parameters — versus this model's trainable ResNet-18, 1-layer decoder, no language, 51.6M.
