Cooperation among robots is a necessary feature of advanced manufacturing and many other applications. The invention relates to systems and methods for robots to identify each other using simultaneous infrared pulses and wireless messages in 5G or 6G. The wireless message can indicate the wireless address of the transmitting robot, and the infrared signal can indicate which robot, among many, is transmitting the wireless message. Thus the other robots can compare the arrival direction of the infrared signal with an optical image, and thereby localize the transmitting robot. The robots can then begin cooperative actions thereafter. The procedures are suitable for mobile robots in a self-driving and self-managing scenario, fixed and mobile robots cooperating to accomplish a task, and robots intermingled with humans. Multiple operating modes are illustrated across a wide range of industries and use cases.
