+SmolVLA training variant of nullPointerExcept1on/realworld_go2_task2 (Go2 walking along a shared pedestrian/car road): RGB only + observation.state=[move] + action=[vx,vy,vyaw]. Unlike realworld_go2_task1_smolvla, **observation.state=[move] is fixed to 1.0 in every frame** (no stop/go hint; the policy must decide from the image alone). Train with --rename_map='{"observation.images.front": "observation.images.camera1"}'. 11 episodes as of 2026-09-10.
