Motor module for carrier robot and associated process

Abstract

The present invention relates to a motor module (200) of a carrier robot (100) inserted into a first conduit (1), the motor module (200) comprising a central body (210) and three arms (220) linked to the central body (210) and comprising: - a drive wheel (222), located at one end of the arm (220) distal to the central body (210); - a geared motor (223); - a pneumatic clutch device (224) configured to engage the drive wheel (222) when it is subjected to a predefined pneumatic pressure and to disengage the drive wheel (222) when the pneumatic pressure exerted is less than the predefined pneumatic pressure; each arm (220) being configured to be movable between a deployed position in which the drive wheel (222) is in contact with the first conduit (1) and a retracted position in which the drive wheel (222) is in contact with the central body (210).
