This is a lower limbs exoskeleton and a method whereby a user fitted with such an exoskeleton moves an object. Said exoskeleton comprising two jointed legs designed to be coupled to the lower limbs of a user, and a connecting member joining together the upper end portions of the legs to which it is jointed and which can be positioned in the region of the pelvis of the user. The exoskeleton also comprises means of actuating the jointed legs according to the movements of the user, and a connecting member wholly situated in front of the upper end portions of the jointed legs when considering the direction of walking.

Exoskelton to be worn on the front and method for using such an exoskeleton

A lower exoskeleton for a user including a pelvic element () with a mechanism for securing to an upper part of the user's body; two lower supports () with a mechanism for securing to the user's lower limbs and which rest on the ground during stance phases, each of the supports having a thigh segment and a tibia segment connected by a knee link to allow flexion and extension; and hip links for connecting the two lower supports to the pelvic element. The pelvic element has a an inner segment () extending symmetrically in relation to a central sagittal plane; and two outer segments () extending symmetrically and connected to respective distal ends of the inner segment by linking members ('), allowing flexion between the inner segment and each outer segment along two orthogonal axes.

The invention relates to collaborative robotic equipment comprising a supporting structure supporting an arm that can be moved along at least one axis and the end of which is equipped with a tool, wherein the arm comprises a first horizontal portion, movable on a vertical axis and connected to the supporting structure by a first pivot, a second pivot providing the rotary connection of a second horizontal portion to the first portion, an end fitting providing connection between the second portion and a motorized tool-holding linear actuator which is fitted with a manual-control stick collaborating with a main force sensor to control the vertical movement of the tool and amplify the manual effort.

Collaborative robotic equipment

The application relates to a device for assisting in actuating a tool comprising two arms that are movable in rotation around an axis between an open position in which the arms are separated from each other, and a closed position in which the arms are close to each other, the device further comprising a cable at one end part of which is associated with one of the arms, the other end part of the cable being disposed in a cable tensioner, the tensioner being associated with the other arm, the device further comprising actuating the tensioner between an open position in which the cable is unwound, the arms being in an open position, and a closed position in which the cable is wound so as to move the arms into their closed position.
