This dataset was created using LeRobot.

assembly_pick_insert

Contact-rich pick-and-insert demonstrations (grasp a free-standing 8 mm peg, transport it, and insert it straight down into a tight socket) generated by a privileged scripted expert in NVIDIA Isaac Lab. The dataset is model-agnostic: keys follow the LIBERO/robosuite VLA convention so pretrained policies (pi0.5/openpi, Qwen robot-manip, Nano/DROID/Cosmos, XVLA) can fine-tune with a trivial adapter.

  • Robot: Franka Panda + Robotiq 2F-85 (DROID standardized platform), operational-space (OSC) delta-EE control with locked gains for this demo set.
  • Control / record rate: 15 Hz (sim 120 Hz, decimation 8). Actions are EE deltas between consecutive recorded frames, so the action rate equals the frame rate.
  • Instruction: "pick up the peg and insert it into the hole"

Observation / action / state layout

key dtype shape meaning / units
observation.images.front video (H.264, CRF 20) (224, 224, 3) third-person/agentview RGB, uint8
observation.images.wrist video (H.264, CRF 20) (224, 224, 3) eye-in-hand RGB, uint8
observation.state float32 (21,) joint_position (7, rad) + gripper_position (1, 0..1) + EE pos (3, m) + EE quat (4, wxyz) + EE wrench (6: force N, torque N·m)
action float32 (7,) EE delta pos (3, m) + delta rotation (3, axis-angle rad) + gripper target (1, normalized)

Frames are in the robot base frame. The first 8 dims of observation.state are the DROID proprio contract (joint_position + gripper_position); EE pose + wrench follow as extras. Wrench models can slice the last 6; DROID-native fine-tuning uses observation.state[:8].
