arkojit1/mj_red_yellow_block

This dataset was created using LeRobot.

Dataset Description

Expert demonstrations of stay still, don't move, do nothing, don't do anything, stop, pick up the red block, lift the red block, pick up the yellow block, lift the yellow block, pick up the green block, lift the green block, pick up the block, pick up a block, lift a block in the mj_pick_block MuJoCo Franka Panda scene.

• Source: dataset recipe red_yellow_block (record_expert_dataset.py)

  • stay_still: 100 episodes
  • pick_red_block: 100 episodes
  • pick_yellow_block: 100 episodes
  • pick_green_block: 100 episodes
  • pick_block: 100 episodes

• Control rate: 50 Hz

• Frames: action.ee.delta_xyz is a gripper-site translation in the MuJoCo world frame (meters). action.ee.orientation is the first two rows of the gripper site's world-frame rotation matrix (site axes expressed in world).

• Observations: observation.image.front, observation.image.wrist (224×224 RGB); observation.state is 7 arm joint positions plus gripper opening in [0, 1] (0 = closed, 1 = open)

• Gripper: target opening in [0, 1] (0 = closed, 1 = open)

• Recorded actions:

  • action.ee.delta_xyz: shape (3,), names ['dx', 'dy', 'dz']
  • action.ee.orientation: shape (6,), names ['r00', 'r01', 'r02', 'r10', 'r11', 'r12']
  • action.joint.delta_angles: shape (7,), names ['joint1', 'joint2', 'joint3', 'joint4', 'joint5', 'joint6', 'joint7']
  • action.gripper.target: shape (1,), names ['gripper']
