Patent number: 12622836Abstract: The present invention relates to a method for generating a trajectory of an exoskeleton (1) provided with two legs each having a foot, the method comprising the implementation by data-processing means (11a) of a server (10a), of steps of: (a) obtaining at least one n-tuple of gait parameters defining a given gait of the exoskeleton (1); (b) generating at least one periodic elementary trajectory of the exoskeleton (1) for said n-tuple of gait parameters, such that said periodic elementary trajectory comprises in sequence a first trajectory portion and a second trajectory portion, such that in the first trajectory portion each foot performs a pure rotation, and in the second portion only one foot performs a translation.Type: GrantFiled: February 10, 2021Date of Patent: May 12, 2026Assignee: WANDERCRAFTInventors: Stanislas Brossette, Guilhem Boeris

Patent number: 11780087Abstract: A method for moving an exoskeleton from a seated position to a standing position (and vice versa) in which none of the degrees of freedom of the exoskeleton is non-actuated. The method includes the implementation by a data processor of steps of: (a) generating a trajectory of the exoskeleton from the seated position to the standing position (and vice versa), the trajectory being parameterised as a function of time; (b) applying to the trajectory a set of virtual constraints on the actuated degrees of freedom, the virtual constraints being parameterised by a phase variable; and (c) running a controller of the exoskeleton associated with the set of virtual constraints such that the exoskeleton moves from the seated position to the standing position (and vice versa), the controller being capable of generating commands for the actuators so as to comply with the virtual constraints during the trajectory.Type: GrantFiled: June 28, 2018Date of Patent: October 10, 2023Assignee: WANDERCRAFTInventors: Matthieu Masselin, Marine Petriaux

Patent number: 11426322Abstract: The present invention relates to a method for moving an exoskeleton (1) receiving a human operator, said exoskeleton (1) having a plurality of degrees of freedom including at least one degree of freedom actuated and at least one non-actuated degree of freedom, the method being characterised in that it comprises the implementation of steps of: (a) when a start request is received, generating and emitting a command to at least one of said actuators so as to put the exoskeleton (1) in a tipping state; (b) in a database stored in data storage means (12) of triplets of: a set of virtual requirements on said actuated degrees of freedom, a controller for said exoskeleton (1) capable of generating commands of said actuators so as to fulfil said virtual requirements by implementing at least one attracting stable trajectory, a stability pool formed by all the points from which the execution of said controller allows a convergence to said attracting stable trajectory; identifying a set of virtual requirements suchType: GrantFiled: January 10, 2018Date of Patent: August 30, 2022Assignee: WANDERCRAFTInventors: Matthieu Masselin, Kien Cuong Nguyen
