Method and device for controlling the motion of one or more collaborative robots

A method for controlling one or more collaborative robots, each one of said one or more collaborative robots being mounted on a fixed or movable base and being equipped with:

• one or more terminal members;
• a motion controller configured to move, along predetermined directions, said one or more terminal members based on a position of at least a human operator;
• wherein said method comprises the following iterative steps:
• determining position coordinates of said human operator;
• determining position coordinates of each one of said terminal members;
• for each terminal member determining, as a function of both said position coordinates of said terminal member and said position coordinates of said human operator, a plurality of productivity indices;
• each productivity index being associated with a respective one of said predetermined directions;
• each productivity index being indicative of a maximum speed at which a respective terminal member can move, in a respective one of said predetermined directions, at least in case of a presence of said human operator;
• supplying to said motion controller said productivity indices;
• activating said motion controller to move, along said predetermined directions, said one or more terminal members based on said productivity indices.
