Fetch

The Fetch environments are based on the 7-DoF Fetch Mobile Manipulator arm, with a two-fingered parallel gripper attached to it. The main environment tasks are the following:

  • FetchReach-v3: Fetch has to move its end-effector to the desired goal position.

  • FetchPush-v3: Fetch has to move a box by pushing it until it reaches a desired goal position.

  • FetchSlide-v3: Fetch has to hit a puck across a long table such that it slides and comes to rest on the desired goal.

  • FetchPickAndPlace-v3: Fetch has to pick up a box from a table using its gripper and move it to a desired goal above the table.
