Abstract: A device for picking or depositing an item from or into a compartment of an automated warehouse has first moving means for moving the device along a main direction and primary electrical power supply means having a pair of forks moved by second moving means along a transverse direction between a retracted position and an extended position. Each fork has an end section having at least one thrust element movable between an operating position and an idle position. The end section has third moving means for moving the at least one thrust element. A central control unit commands moving parts of the device. The end section has a peripheral control unit for the third moving means. The end section has rechargeable secondary electrical power supply means for supplying power to the peripheral control unit and to the third moving means.
