        'action': Tensor(shape=(7,), dtype=float32, description=Robot action, consists of [3x end effector delta target position, 3x end effector delta target orientation in axis-angle format, 1x gripper target position (mimic for two fingers)]. For delta target position, an action of -1 maps to a robot movement of -0.1m, and action of 1 maps to a movement of 0.1m. For delta target orientation, its encoded angle is mapped to a range of [-0.1rad, 0.1rad] for robot execution. For example, an action of [1, 0, 0] means rotating along the x-axis by 0.1 rad. For gripper target position, an action of -1 means close, and an action of 1 means open.),

The pose is represented in the world frame. This variable is used to specify the target object or object part when multiple objects or object parts are present in an environment),
