Abstract: The invention relates to a cooperative mobile robot, characterized in that it comprises a slim structure (12) in the form of a column in a main longitudinal direction (13) which is oriented substantially upwards when the robot is in the operating position, at least one locomotion means (14) which is arranged at a lower end of said slim structure (12) and is configured to provide at least a first point of contact with the ground when the robot is in the operating position, at least one stabilization means (20) which is connected to the slim structure (12) and is configured to provide at least a second point of contact with the ground when the robot is in the operating position, and at least one attachment means (16) which is configured to receive at least one means of structural connection with another cooperative mobile robot.

Abstract: A curved blade for a delimbing head operable to cut branches from a felled tree is disclosed. The curved blade comprises a cutting rim, at least one portion of which comprises a continuous flange defining a continuous cutting edge, as well as at least one row of ribs that are straight and parallel to each other, extending in the direction of at least one face of the cutting rim from the continuous flange. The continuous cutting edge of the blade having these straight parallel ribs reduces the lateral load of the continuous cutting edge during the operation of cutting branches from a felled tree.

Abstract: This curved blade (20) comprises a cutting rim (30), at least one portion of which comprises a continuous flange (31) defining a continuous cutting edge, as well as at least one row of ribs (32), the longitudinal axes (Alg) of which are straight and parallel to each other, extending in the direction of at least one face of the cutting rim, from this continuous flange. The blade in accordance with the invention allows reducing the cutting forces, in comparison with a non-ribbed curved blade, as used in the prior art. Indeed, the continuous edge is associated with ribs which serve to reduce the lateral load of this continuous edge. Consequently, it is possible to size the flange and the edge, without any risk of breakage, so as to present a reduced contact surface with the tree, which improves cutting of the matter.

Abstract: The invention relates to a load transporting mono-robot (10), comprising (i) a gantry (19) having two lateral uprights (11) that are connected at their upper ends by a cross beam (12), each of the lower ends being equipped with propulsion means linked to the upright (11) by a motorized pivot (18), and (ii) means for gripping a load that are positioned between the lateral uprights (11) linked to the cross beam (12) by a kinematic chain for positioning and orientation that is configured to allow the means for gripping a load to rotate about an axis substantially normal to the cross beam (12) and is located substantially in the plane defined by the gantry (19), and to allow the means for gripping a load to rotate about an axis substantially normal to the plane defined by the gantry (19). The invention also relates to a method for transporting a load that uses a plurality of mono-robots (10) and also to two methods for crossing obstacles, ensuring the stability of a poly-robot and its load.

Abstract: A climbing robot that can move along a post having a vertical axis comprises a frame fitted with motorized movement assembly for moving along the post and with a module for controlling and commanding the motorized movement assembly. The motorized movement assembly comprises a bracing structure wherein the center of gravity is at a distance from the axis of the post and which comprise at least two rolling contact elements designed to be in contact with the post, including at least one motorized rolling contact element called the propulsion contact element.
