Abstract
Methods for controlling at least two robots having respective working spaces, including at least one region in common are disclosed. The working space of each robot is modelled by defining one or more interference regions each constituted by an elementary geometrical figure. The interference regions are classified as: prohibited interference regions, defined as regions of space where the presence of the robot must without fail always be inhibited; monitored interference regions, defined as regions of space where the presence of the robot is accepted, but controlled, the robot being pre-arranged for sending a signal to the central control unit whenever it enters a monitored region and whenever it exits from a monitored region; and hybrid interference regions that are able to change between a status of monitored region and a status of prohibited region as a function of an input signal to the robot sent by said central control unit.
