Motorised walker comprising a frame having a front part and a rear part, a pair of wheels being arranged to support the rear part of the frame, and at least one wheel being arranged to support the front part of the frame, at least one of the wheels being coupled to a movement motor, wherein: - the frame is fitted with two verticalization ramps, said verticalization ramps having a longitudinal axis forming an angle of between 20° and 40° with an axis perpendicular to the ground, each of said verticalization ramps being associated with an electronic handle able to move in translation along the verticalization ramp with which it is associated, - it comprises at least one verticalization motor arranged to enable a synchronous movement of the electronic handles along the verticalization ramps, said movement being able to transition a user of the walker from a seated position to a standing position, - at least one of the electronic handles comprising at least two sensors operatively coupled to a control module, one being configured to measure a horizontal component and the other to measure a vertical component of a force applied to said electronic handle by the user, said control module being configured to be able to control the verticalization motor and the movement motor, and the verticalization motor and the movement motor being controlled according to values transmitted by the sensors of the electronic handle, the control module being configured to calculate an index of intention and an indicator of movement of a user of the walker corresponding to an interaction of the user with the walker, the index of intention being, in part, calculated from the value of the measurement of the vertical component, and the indicator of movement, at least in part, from the value of the measurement of the horizontal component of the applied force. - the frame is fitted with two verticalization ramps, said verticalization ramps having a longitudinal axis forming an angle of between 20° and 40° with an axis perpendicular to the ground, each of said verticalization ramps being associated with an electronic handle able to move in translation along the verticalization ramp with which it is associated, - it comprises at least one verticalization motor arranged to enable a synchronous movement of the electronic handles along the verticalization ramps, said movement being able to transition a user of the walker from a seated position to a standing position, - at least one of the electronic handles comprising at least two sensors operatively coupled to a control module, one being configured to measure a horizontal component and the other to measure a vertical component of a force applied to said electronic handle by the user, said control module being configured to be able to control the verticalization motor and the movement motor, and the verticalization motor and the movement motor being controlled according to values transmitted by the sensors of the electronic handle, the control module being configured to calculate an index of intention and an indicator of movement of a user of the walker corresponding to an interaction of the user with the walker, the index of intention being, in part, calculated from the value of the measurement of the vertical component, and the indicator of movement, at least in part, from the value of the measurement of the horizontal component of the applied force.
