Abstract:
1. A robot or motorized structure having an external surface of which at least one portion is covered by a detector device comprising an electromechanical transducer including a substrate, a first series of electrodes, a second series of electrodes, and a deformable material layer associated with the electrodes of the two series, wherein the substrate, the electrodes, and the deformable material layer form a single unit mounted on said portion and are arranged so that a current flowing between one of the electrodes of the first series and an adjacent electrode of the second series is proportional to a thickness of the deformable material layer in register with said electrodes, the substrate including a base layer to which are attached the electrodes of the first series and the electrodes of the second series, which have facing portions, and a variable conduction layer that covers the base layer and the electrodes, the robot or motorized structure comprising: a control unit that is connected to at least one motor of the motorized structure and to the device and that is programmed to control the at least one motor to have the motorized structure perform a movement and to interrupt the movement as soon as a current is detected between two electrodes of the device, the deformable material layer having a thickness and a flexibility such that, for a predetermined speed of the motorized structure, the control unit is able to interrupt movement of the motorized structure before a maximum crushing of the deformable material layer.
