1 Dataset Description

This dataset includes 62 Lightwheel-Robocasa-Tasks, collected using the g1-controller robot in environments provided by LW-BenchHub.
The robot configuration used during data collection is G1-Controller, using UnitreeG1ControllerEnvCfg inherits from UnitreeG1EnvCfg.

1.1 Robot State

The robot state recorded in the environment is stored in: observation.state

Dimension: 31
Description: Joint positions of the robot
Joint mapping: The exact joint ordering and semantics can be found in the Dataset Structure section below.

1.2 Robot Action

The robot actions are recorded in: action

Dimension: 19
The action is ordered as: base (3), left arm (7), right arm (7), left hand (1), right hand (1).

Component	Dimension	Description
Base action	3	Planar base motion in world frame
Arm action	14	7-DOF left arm + 7-DOF right arm (end-effector poses)
Hand action	2	Continuous gripper control

        "right_wrist_roll_joint",
        "right_wrist_pitch_joint",
        "right_wrist_yaw_joint"
    ])

1.2.1 Base Action

The base action is implemented using RelativeJointPositionActionCfg, you can refer to the G1PinkActionsCfg above.

Controlled dimensions:
- base_x_joint (index 0): Forward/backward movement in world frame
- base_y_joint (index 1): Left/right movement in world frame
- base_yaw_joint (index 2): Yaw rotation
Scale:
- base_x_joint: 0.01
- base_y_joint: 0.01
- base_yaw_joint: 0.02

1.2.2 Arm Action

The arm actions control the end-effector poses (position and orientation) in the robot root frame.
The 14-dimensional arm action is passed to G1ActionCfg, where it is interpreted as a pose vector: [left_arm_pos (3), left_arm_quat (4), right_arm_pos (3), right_arm_quat (4)]
This pose representation is then converted into a 14-dimensional joint-space command via inverse kinematics.

Left arm action (indices 3-9):
- left_arm_pos_x (index 3): X position in robot root frame
- left_arm_pos_y (index 4): Y position in robot root frame
- left_arm_pos_z (index 5): Z position in robot root frame
- left_arm_quat_w (index 6): Quaternion w component
- left_arm_quat_x (index 7): Quaternion x component
- left_arm_quat_y (index 8): Quaternion y component
- left_arm_quat_z (index 9): Quaternion z component
Right arm action (indices 10-16):
- right_arm_pos_x (index 10): X position in robot root frame
- right_arm_pos_y (index 11): Y position in robot root frame
- right_arm_pos_z (index 12): Z position in robot root frame
- right_arm_quat_w (index 13): Quaternion w component
- right_arm_quat_x (index 14): Quaternion x component
- right_arm_quat_y (index 15): Quaternion y component
- right_arm_quat_z (index 16): Quaternion z component
Coordinate frame: Robot root frame

1.2.3 Gripper Action

Grippers are controlled using continuous values. In the action data, -1.0 indicates fully open, +1.0 indicates fully closed.

Action values:
- -1.0: fully open gripper
- +1.0: fully closed gripper
- Continuous values in between represent partial opening/closing
Left gripper (index 17): Continuous value from -1.0 (open) to 1.0 (closed)
Right gripper (index 18): Continuous value from -1.0 (open) to 1.0 (closed)
Source: VR trigger mapping
- trigger=0.0 (not pressed) → -1.0 (open)
- trigger=1.0 (fully pressed) → 1.0 (closed)
