A robot system (X-Z) includes a plurality of manipulators (1x-2x, 1y-2y, 1w-2w, 1z-2z) and a portable terminal (3), said terminal being able to connect to the manipulators in wireless mode. The system is conceived so as to enable the terminal (3) to connect to a first manipulator (1x-2x) in a programming mode (Main) and, during the same session, to connect to a second manipulator (1w, 2w) in a monitoring mode (Secondary).
