SO-101 Pick Cube Dataset

Dataset Preview

A robotics manipulation dataset featuring the SO-101 robot arm performing pick-and-place tasks in MuJoCo simulation. The robot learns to pick up a cube and place it into a bin.

Dataset Details

Property	Value
Robot	SO-101 (6-DoF arm with gripper)
Task	Pick cube and place in bin
Episodes	993
FPS	30
Cameras	3 (front, overhead, wrist)
Resolution	640x480
Format	LeRobot v2.0

Cameras

Front Camera: Third-person view of the workspace
Overhead Camera: Top-down bird's eye view
Wrist Camera: First-person view from the gripper

Joint States

The dataset includes 6 joint positions and actions:

shoulder_pan - Base rotation
shoulder_lift - Shoulder elevation
elbow_flex - Elbow bend
wrist_flex - Wrist pitch
wrist_roll - Wrist rotation
gripper - Gripper open/close

Usage

from lerobot.common.datasets.lerobot_dataset import LeRobotDataset

dataset = LeRobotDataset("gpudad/so101_pick_cube")
print(f"Number of episodes: {dataset.num_episodes}")
print(f"Number of frames: {dataset.num_frames}")

Training with LeRobot

# Train ACT policy
python lerobot/scripts/train.py \
  --dataset.repo_id=gpudad/so101_pick_cube \
  --policy=act \
  --output_dir=outputs/act_so101_pick_cube

Environment

The simulation environment uses MuJoCo with:

SO-101 robot arm mounted on a table
A colored cube as the manipulation target
A bin as the placement destination
Randomized cube positions for diverse training data
