click_bell (atomic)

Scene

Flat tabletop, dual-arm robot. One small desk bell at random pose within xlim=[-0.25, 0.25], ylim=[-0.2, 0.0].

Goal

Press the top of the bell once. Use the arm closer to the bell (left if x<0 else right). RoboTwin's check_success checks gripper-close near the bell.

Why this is the zeroshot demo

  • Single object → one perception query
  • Single primitive action: "above + down + close"
  • No tool grasp / re-orientation
  • ~3-5 tool calls minimum, fits in a 12-step VLM budget

Lifecycle

sub-skillwhat it does
zeroshot/VLM uses base/robotwin/* tools to click the bell. Successful runs land in DataStore.
train/LeRobot v3 dataset + ACT/π₀ finetune (small for plumbing demo).
eval/Held-out seed eval; switches active_executor to policy:vN once rate ≥ threshold (0.40).
reset_success/env.reset(next_seed) — sim is free.
reset_failure/VLM-driven mode classification + recovery. Fallback in sim: env.reset.
