open-bottle (sim, scripted): 5 sim demos in the ROBOTIS MCAP layout
5 Isaac Lab demos of opening a screw-cap bottle with two arms, written in the same layout as the real Cyclo
Intelligence recordings (format_version: robotis_v2, one folder per demo with <i>_0.mcap, metadata.yaml,
episode_info.json, camera_info/, robot.urdf, videos/<i>_0/<cam>.mp4), so they can be replayed on the real robot
like the earlier *-replay5 sets. Leader command topics = the sim joint targets (16: both arms + grippers),
/joint_states = the sim joint state, both resampled from 15 Hz to 100 Hz; videos frame-repeated to 30 fps. The sim has no
right head camera, so cam_right_head.mp4 is a copy of the left head video.
The motion (user's plan, 2026-11-06). The bottle stands upright on the table. The left hand opens fully, grasps the bottle by its lower end (5 cm up, from the bottle's left, 30 deg down), lifts it 3 cm and levels it. The right hand comes in level from the side, half open, centres on the cap, closes to 0.70 (not yet touching), sets its pad's bottom edge 1.5 mm above the cap rim (the cap is 11 mm tall, the pad 26 mm wide), squeezes to 0.79, and twists the cap 45 deg about its axis at 10 deg/s, rising with the thread. It lets go, backs out, rises 6 cm, returns above the bottle to the same start pose and pinches again, until the thread releases (after 195 deg; the cap then lifts off in the right hand). All 5 demos succeeded in sim: the cap came free, stayed between the right pads and was lifted off; the bottle stayed in the left hand and both arms kept at least 5 cm of surface clearance.
The sim is set up to match the real robot: FFW SG2, ROBOTIS RH-P12-RN CAD gripper visuals with calibrated wrist cameras, 29.25 in table. The bottle is an empty BODYARMOR LYTE 28 oz (86 mm body, 212 mm with cap, 45 g) with a 38 mm 3-start screw cap (41.5 mm, 11 mm tall) modelled as a thread joint: it turns at 0.40 N m (hand-tight), rises 1.91 mm/rad and lets go after 195 deg.
Things to check on the real robot before replaying: the left gripper is commanded fully open (0.0, ~107 mm pad gap) for the 86 mm bottle; the right close is 0.79 on the 41.5 mm cap (the real cap torque and pad friction set how much the cap slips per stroke, so the real cap may need more or fewer of the recorded strokes).
