Adroit Hand#

This environments consists of a Shadow Dexterous Hand attached to a free arm. The system can have up to 30 actuated degrees of freedom. There are 4 possible environments that can be initialized depending on the task to be solved:

  • AdroitHandDoor-v1: The hand has to open a door with a latch.

  • AdroitHandHammer-v1: The hand has to hammer a nail inside a board.

  • AdroitHandPen-v1: The hand has to manipulate a pen until it achieves a desired goal position and rotation.

  • AdroitHandRelocate-v1: The hand has to pick up a ball and move it to a target location.

A sparse reward variant of each environment is also provided. These environments have a reward of 10.0 for achieving the target goal, and -0.1 otherwise. They can be initialized via:

  • AdroitHandDoorSparse-v1

  • AdroitHandHammerSparse-v1

  • AdroitHandPenSparse-v1

  • AdroitHandRelocateSparse-v1
