ROBOTIC CLAW TO GRIP AN OBJECT

The invention relates in particular to a robotic gripper that has parts with variable stiffness over rigid structures. The new design makes it possible to grip delicate and complex geometrical objects, such as fruit, without damaging them. Robotic claw to grasp an object (9), comprising one or more fingers (10) equipped with a flat articulated mechanism provided with two or more rigid links (4, 5, 6, 7) articulated to each other and adapted to rotate around a support point (13), an actuating mechanism (12) that provides a force that rotates the finger (10) around said support point (13), where said robotic claw is characterized in that at least two rigid links (5, 6) are attached to a flexible piece (8) configured to deform when in contact with the object (9) adapting to the shape thereof, so that, when the actuator mechanism (12) rotates the finger (10) around the support point (13), the resistance to deformation of the flexible part (8) prevents relative rotation between the rigid links (4, 5, 6, 7) during the rotation of the finger (10), and, once the flexible piece (8) comes into contact with the object (9), it is deformed allowing the relative rotation between the rigid links gone (4, 5, 6, 7) that, as a consequence, embrace the object (9) executing an enveloping grip.
