Richard-Nai/HuMI-Squat-Pick-Ground

Dataset Card for HuMI

[Project Page] | [Paper]

Dataset Summary

This dataset was collected using the HuMI data collection pipeline and converted into the LeRobot format. It provides robot-free demonstrations for humanoid whole-body manipulation.

Task Description: This repository features a squat-and-pick-up task, where the humanoid squats, grasps a bottle placed on the floor, and lifts it from the ground.

The dataset consists of 410 demonstrations collected across 7 different environments.

Dataset Structure

Data Instances

Each instance in the dataset represents a single frame from an episode. The data includes synchronized camera observations, end-effector poses, joint positions, and task instructions.

Data Fields

The dataset contains the following features:

• task (string): The natural language description of the task.
• observation.images.camera{cam_id}_rgb (video, (H, W, 3)): RGB observations from the cameras.
• {robot_name}_eef_pos (float32, (3,)): End-effector position (x, y, z).
• {robot_name}_eef_rot_axis_angle (float32, (3,)): End-effector rotation in axis-angle representation.
• {robot_name}_gripper_width (float32, (1,)): Gripper width (only present for gripper end-effectors).
• {robot_name}_demo_start_pose (float32, (6,)): Initial 6DoF pose of the end-effector for the demonstration.
• {robot_name}_demo_end_pose (float32, (6,)): Final 6DoF pose of the end-effector for the demonstration.
• joint_pos (float32, (29,)): Full joint positions of the Unitree G1 robot, computed via inverse kinematics using the end-effector poses as targets.

For the HuMI setup, we recorded images from two wrist-mounted cameras, where camera0 corresponds to the right gripper and camera1 corresponds to the left. Additionally, we recorded trajectories for five end-effectors, adopting the naming convention from UMI:

• robot0: right gripper
• robot1: left gripper
• robot2: pelvis
• robot3: right foot
• robot4: left foot
