A method to assist with the production of an assembly of two elements implemented by a remotely operated robot. The method includes an arm, hinged to the end of which is mounted a heat-supply member suitable for delivering heat to a heat-supply point; position sensors; guiding actuators; a video capture device; an interface; and a processing unit. The method involves the following steps: acquiring a type of assembly to be produced; calculating a reference path of the heat-supply point; defining a shell for guiding the heat-supply member; and controlling guiding actuators so as to prevent the heat-supply member from moving out of the guiding shell.

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.

Lower exoskeleton

The invention relates to an assist arm intended to be fitted on an exoskeleton, having a mounting plate () carrying a drive member (), a shoulder segment () articulated on the mounting plate, an arm segment () having a proximal end articulated on the shoulder segment, a forearm segment () having a proximal end articulated on a distal end of the arm segment, an actuating cable () driven by the drive member and forming two strands () which extend parallel to the first axis in order to pass through the first articulation and to wind around a receiving pulley () which is mounted in a rotating manner about the second axis and which rotates as one with the arm, and connecting means () coupled between the shoulder segment and the forearm second segment and arranged such that a flexion of the arm segment causes a concomitant flexion of the forearm segment.
