"Could you please demonstrate the information of each dimension corresponding to the state dictionary inside the obs in the dataset?" #107
Comments
Please see the If you are not using a wrapper (e.g., ManiSkill2-Learn), then if you are under visual observation mode (rgbd & pointcloud) and print out If you are using the state observation mode, then in particular, for PickCube-v0, the state dimension is 51, which contains (1) from If you are using ManiSkill2-Learn wrapper and using any of the visual observation modes (which I guess it's your case), see https://github.com/haosulab/ManiSkill2-Learn/blob/83dfe26c73b6ce6b0388a0fa07493f340e36dd44/maniskill2_learn/env/wrappers.py#L235 for the environment wrapper. For the 38-dimensional "state" output from the wrapper, it contains agent qpos (state[:9]) & qvel (state[9:18]) & agent base_pose (state[18:25]) & agent tcp_pose (state[25:32]) & goal pos (state[32:35]) & tcp_to_goal_pos (state[35:38]) |
Why does "agent qpos" have 9 dimensions, and what does each dimension represent? |
The first 7 dimensions are panda joint positions; the last 2 dimensions are panda gripper positions |
what is the mean of the base_pose and tcp_bose |
Pose = concat(xyz position, rotation), rotation is represented in the format of quaternion in our state space |
May I know the respective value ranges for these 38 dimensions? |
States corresponding to robot qpos are bounded by joint angle ranges. Other dims are unbounded. |
"Could you please demonstrate the information of each dimension corresponding to the state dictionary inside the obs in the dataset?" For example, what information each of the 38 dimensions in the state dictionary of the pickcube environment represents, and what each dimension corresponds to in terms of information.
