Constant travel-time robotic cells with a single gripper robot and with one or more machines at each processing stage … have been studied in the literature. By contrast, cells with a dual gripper robot, although more productive, have so far … gripper robotic cells that produce identical parts. The objective is to find a cyclic sequence of robot moves that minimizes …

dual-gripper switch time is less than twice the intermachine robot movement time. A computational study demonstrates that … practical insights that are useful in maximizing productivity of any cell configuration with either type of robot …
