A deflection element () for robot arms has two arm braces that are pivotally mounted on a joint mechanism. In order to create a universally useable deflection element, the two arm braces () are each mounted on a support structure () of the joint mechanism by means of an arm joint (), and the two arms braces () are coupled to a connecting element () between the two arm joints (), said connecting element () being movable relative to the support structure (); furthermore, at least one actuating element (), which moves the connecting element () and thus pivots the arm braces () between the end positions thereof, is arranged between the support structure () and the connecting element ().

Deflection element

A control element () has at least one elastic internal part () that can be connected, via a connection, to a pressurized fluid source and/or a vacuum source, which permits pressurization or evacuation of a cavity in the internal part (). In order to provide a control member for general use, it is proposed that the elasticity module of a wall () bounding the internal part () is formed differently in certain sections such that, instead of a homogeneous increase or decrease in volume under pressurization or evacuation, an oriented change in shape takes place, between a resting state and a pressurized or evacuated state, that describes a control path of the control element ().
