Abstract: The present disclosure relates to robotics, and in particular to a self-disinfecting robot. According to a first aspect, the disclosure relates to a self-disinfecting robot comprising an exterior surface (20). The robot (1) comprises at least one light emitting component (12) arranged to illuminate at least a part of the exterior surface (20) with disinfecting light from inside the robot. By projecting disinfecting light from the inside of the robot (1), one may provide a constant and complete disinfection of the exterior surface (or selected parts of it) e.g. during service or operation, including when the robot is moving around. The solution also allows disinfection of e.g. crevices that would also be difficult to disinfect from the outside. Furthermore, the robot may also, to some extent, treat the surrounding environment and in particular the airborne particles around the robot. The disclosure also relates to a corresponding method for disinfecting a robot, to a computer program and to a computer program product.

Abstract: Electrical contact system with a first and a second contact (1, 5), each having a contact surface (4, 8). The first electric contact (1) has a mesostructured electric contact portion (14) with a plurality of slots (15) and ridges (16) formed between neighboring slots (16) of the plurality of slots (16).
