Abstract: In an example, there is disclosed a method for determining a material in a cargo, the cargo including a first object made of a first material and a second object made of a second material. The method includes obtaining image data associated with an inspection image of the cargo, for at least two levels of radiation energy, obtaining equivalence data associated with mass equivalence of at least one of the first material and the second material with respect to a reference material, for the at least two levels of radiation energy, obtaining observation data based on the image data and the equivalence data, and determining at least one of the first material and the second material, based on the obtained observation data.

Abstract: 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.

Abstract: A lower exoskeleton for a user including a pelvic element (1) with a mechanism for securing to an upper part of the user's body; two lower supports (2) 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 (30) extending symmetrically in relation to a central sagittal plane; and two outer segments (33) extending symmetrically and connected to respective distal ends of the inner segment by linking members (31, 32, 34; 31?), allowing flexion between the inner segment and each outer segment along two orthogonal axes.

Abstract: The invention relates to an assist arm intended to be fitted on an exoskeleton, having a mounting plate (2) carrying a drive member (20), a shoulder segment (4) articulated on the mounting plate, an arm segment (6) having a proximal end articulated on the shoulder segment, a forearm segment (8) having a proximal end articulated on a distal end of the arm segment, an actuating cable (27) driven by the drive member and forming two strands (27a, 27b) which extend parallel to the first axis in order to pass through the first articulation and to wind around a receiving pulley (30) which is mounted in a rotating manner about the second axis and which rotates as one with the arm, and connecting means (31, 32, 33) 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.

Abstract: The invention relates to a lower exoskeleton intended to be worn by a user and comprising: a pelvic element (1) provided with means for securing to an upper part of the user's body; two lower supports (2) which are provided with means for securing to the user's lower limbs and which rest on the ground during stance phases, each of said supports comprising a thigh segment and a tibia segment connected by a knee link configured to allow flexion and extension between the thigh segment and the leg segment; and hip links for connecting the two lower supports to the pelvic element.

Abstract: The present invention relates to a method of calibrating the position of a multiply-articulated system, notably a robot. The multiply-articulated system consisting of a chain of N segments interlinked by an articulated link, the calibration minimizing the difference between the measured position Xm of a member linked to the last segment of the chain and its calculated position XC, XC being equal to the product A1.A2 . . . Ai . . . AN.XN, a homogeneous transformation matrix Ai being associated with each segment of order i, this matrix being a function of configuration parameters of the system and of given generalized parameters characterizing the flexibility of the segment, the method comprises: a first step of calculating a flexible model of the system consisting of the matrices A1, A2 . . . Ai . . .

Abstract: The train (1) of modules (2 to 6) that forms the robot comprises springs (38) to connect the successive modules together enabling curvature of the train in the bends of a pipe. However, cables (41) bring the modules together by compressing the springs when they are pulled, until the conical end faces (39, 40) are engaged in each other; the train is made rigid and can be immobilised inside the pipe to perform different types of machining operations, including welding or cutting joints between successive pipes in the pipework.
