Patent number: 11434081Abstract: An autonomous vehicle, for example, an automated guided vehicle or an autonomous mobile robot, has a support structure having a general double-hull configuration, with two separate longitudinal hulls, parallel to each other and transversely spaced apart, and at least two bridge structures that connect the hulls to each other. The aforesaid bridge structures have ends connected to the two hulls by interposition of elastic joints, in such a way that the two hulls are free to perform differentiated oscillating movements so as to allow the front wheels and the rear wheels of the vehicle to remain in contact with the surface on which the vehicle is moving, even when this surface has irregularities and/or slope variations.Type: GrantFiled: September 4, 2019Date of Patent: September 6, 2022Assignee: Comau S.p.A.Inventors: Enrico Mauletti, Enrico Rui, Mauro Berzano, Ivan Lazzero, Simone Romeo

Patent number: 9700952Abstract: An electric spot welding head for a multi-axis industrial robot that has a compact configuration, particularly in a longitudinal direction that goes from the end of the head for the attachment to the robot wrist towards the welding electrodes. This result is achieved primarily by the fact that the electrical transformer mounted on the head has its output connected to the electrode-holding arms arranged, respectively, on a front wall of the body of the transformer and on an end wall of the body of the transformer, for the connection to the electrode-holding arms of the head. The structure of the welding head is completely covered by a casing having a rear opening for connection to the robot wrist and a front opening from which the electrode arms of the welding head protrude.Type: GrantFiled: May 13, 2013Date of Patent: July 11, 2017Assignee: COMAU S.P.A.Inventors: Fulvio Ferrero, Enrico Mauletti

Patent number: 8818558Abstract: Methods for controlling at least two robots having respective working spaces, including at least one region in common are disclosed. The working space of each robot is modelled by defining one or more interference regions each constituted by an elementary geometrical figure. The interference regions are classified as: prohibited interference regions, defined as regions of space where the presence of the robot must without fail always be inhibited; monitored interference regions, defined as regions of space where the presence of the robot is accepted, but controlled, the robot being pre-arranged for sending a signal to the central control unit whenever it enters a monitored region and whenever it exits from a monitored region; and hybrid interference regions that are able to change between a status of monitored region and a status of prohibited region as a function of an input signal to the robot sent by said central control unit.Type: GrantFiled: May 16, 2012Date of Patent: August 26, 2014Assignee: Comau S.p.A.Inventors: Rosario Cassano, Bruno Cicciarello, Elena Grassi, Luca Lachello, Enrico Mauletti, Fabrizio Romanelli

Patent number: 7786404Abstract: A plurality of stretches of laser weld are executed on a structure to be welded by means of a device for focusing and orientation of the laser beam, which is associated to a component element of a manipulator robot. The focusing head is kept in the proximity of, but not closely adjacent to, the different areas to be welded and can consequently follow a simplified path, whilst the device for orientation of the laser beam aims the latter on the different areas of the structure to be welded, so that the speed of travel of the laser beam spot along the longitudinal direction of the weld stretch is independent from the speed of travel of the robot end element.Type: GrantFiled: December 14, 2004Date of Patent: August 31, 2010Assignee: Comau S.p.A.Inventors: Roberto Menin, Arturo Baroncelli, Enrico Mauletti
