portal-rebot-pick-microcontroller
A LeRobot dataset of a 6-DOF arm picking a microcontroller and placing it in a box. Episodes were collected by teleoperating a real robot over the network with LiveKit Portal, using a human-in-the-loop recording loop that aligns camera frames and joint state into clean, synchronized trajectories.
Task: Pick the microcontroller and place it in the box

Features
observation.state— 7 absolute joint positions (degrees):shoulder_pan,shoulder_lift,elbow_flex,wrist_flex,wrist_yaw,wrist_roll,gripper.action— same 7 joint positions, the commanded targets (from human teleop or a policy during handoff).observation.images.arm_camera— arm-mounted RGB camera, 640×480, 30 fps.observation.images.overhead_camera— overhead RGB camera, 640×480, 30 fps.
How it was collected
Data was recorded with LiveKit Portal's human-in-the-loop pipeline: a robot publishes
camera frames and joint state, an operator (human teleoperator and/or policy) drives it,
and every executed action is recorded tagged with its sender. The synchronizer stitches
the separately-arriving camera and state streams back into one coherent snapshot per tick
before writing each frame to the LeRobotDataset episode.
Usage
from lerobot.datasets.lerobot_dataset import LeRobotDataset
dataset = LeRobotDataset("binhpham/portal-rebot-pick-microcontroller")

Versions
- v3 — 50 episodes. A stray, partially-recorded frame fragment (from an accidental record toggle) was dropped during repacking; all 50 intended episodes are intact.
