FIELD: machine building.
SUBSTANCE: invention refers to handlers, particularly to wrist of robot arm. Wrist (20) consists of: first support element (22) mounted on component of a robot and rotating around axis (IV), of second support element (24) mounted on support component (22) and rotating around axis (V) positioned at angle relative to axis(IV), and of first engine (28), base of which is support component (22). A shaft of first engine (28) is connected at its rotation with support component (24) by means of the first tooth gear. Further, the wrist consists of third support component (26) mounted on support component (24) and rotating around third axis (VI) positioned at angle relative to axis (V), and of second engine (30) supported with support component (24). The shaft of second engine (30) at rotation is connected to third support component (26) via the second tooth gear.
EFFECT: reduced cost and simplification of design.
