Title (EN) MOBILE ROBOTIC DEVICE WITH IMPROVED ARCHIMEDEAN SCREW PROPULSION MECHANISM
(FR) DISPOSITIF ROBOTIQUE MOBILE AVEC MÉCANISME DE PROPULSION À VIS D'ARCHIMÈDE AMÉLIORÉ
Abstract: front page image
(EN)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.
(FR)L'invention se situe dans le domaine des robots mobiles. Elle concerne un dispositif robotique mobile comprenant un mécanisme de propulsion équipé d'une vis d'Archimède, de manière à permettre un déplacement sur différents types de sol. Selon l'invention, le dispositif robotique mobile comporte un corps et un mécanisme de propulsion (40), le mécanisme de propulsion comprenant: un tambour (42) mobile en rotation par rapport au corps, un filet de vis d'Archimède (43) en saillie sur une surface extérieure du tambour, et des organes de roulement (44) comportant chacun une structure support (441) et une roue (442), chaque structure support formant une portion du filet et chaque roue étant montée en liaison pivot sur la structure support, chaque organe de roulement comprenant au moins un évidement (4417, 4418) agencé pour minimiser les surfaces adjacentes entre la structure support et la roue.
