Abstract (en)
[origin: WO2018065710A1] The invention falls within the field of mobile robots. It relates to a mobile robotic device comprising a propulsion mechanism equipped with an Archimedean screw, so as to allow it to move over various types of ground. According to the invention, the mobile robotic device comprises a body and a propulsion mechanism (40), the propulsion mechanism comprising: a drum (42) capable of rotating with respect to the body, and archimedean screw thread (43) projecting from an exterior surface of the drum, and rolling members (44) each one comprising a support structure (441) and a wheel (442), each support structure forming a portion of the screw thread and each wheel being mounted as a pivot connection on the support structure, each rolling member comprising at least one cavity (4417, 4418) designed to minimize the adjacent surface areas between the support structure and the wheel.
