2. A robot is to be programmed to unload parts from one pallet and load them onto another pallet. The parts are located on the unload pallet (pallet 1) in a 3 by 4 pattern in known fixed positions, 40 mm apart in both directions. The two directions of the pallet are assumed to be parallel to the x and y world coordinate axes of the robot. The parts are to be placed on the load pallet (pallet 2) in a 2 by 6 pattern, 40 mm apart in both directions. The two directions of the pallet are again assumed to be parallel to the x and y world coordinate axes of the robot. Make a sketch of the workstation setup before you begin programming.
