They can carry objects and operate tools to complete various tasks.

[0003] For example, the Chinese patent with announcement number CN210551179U (heavy-load truss robot): includes multiple columns, beams, two auxiliary beams, pallets, vertical beams and grippers. Multiple columns are fixed at the bottom of each auxiliary beam. The beam is set between the two auxiliary beams, and the beam can slide forward and backward along the length of the auxiliary beam. The beam is provided with a pallet that slides left and right along its length. The vertical beam is slidably installed on the pallet. A gripper is fixed at the bottom of the vertical beam, and the vertical beam can slide up and down along its length.
