Task / 환경 정보
- Task:
RobotisLab-CallButton-Right-OMY-Aux-v0 - Sim: Isaac Sim 5.1, Isaac Lab
- Robot: OMY (6-DoF, RH-P12-RN gripper, 4-finger mimic)
- Scene:
- Pedestal (cube, 0.8m × 0.8m × 0.908m)
- Robot mounted on pedestal
- Elevator (random USD from 100 variants per episode, hall-side facing)
- Call button (CallBtn_0) on right side
- Light: DomeLight 5600 intensity, randomized per episode
- Robot init: front-of-button, 55-65cm standoff, ±5cm lateral random, joint randomization (Gaussian, std 0.02 rad)

Teacher Phases (per demo)
| Phase | Steps (30Hz) | 설명 |
|---|---|---|
| settle | initial | Gripper close + physics settle |
| approach | 50 | Joint-space cubic smoothstep HOME → goal_pre_q (IKPy) |
| press | up to 200 | DLS micro-thrust 4mm/step toward button (PUSH_STEP_M=0.004) |
| hold | 15 | Dwell after contact |
| retract | 150 | Smoothstep back to goal_pre_q |
| home_idle | 75 | Hold at HOME |
Press validation: gripper finger contact force > 5N triggers FSM button press → LED + door.
Notes / 비고
- Per-demo 30 Hz action rate is more realistic for real-world deployment (vs 60 Hz). Total wall-time per demo ~19s.
- All 40 demos verified
success=True(pressed + LED lit + door opened + home reached). - Image dimensions match Isaac Sim camera annotator output (1920 × 1200 PinholeCameraCfg).
