Abstract
A gripper device comprising at least two portions which are coupled together and which can be moved towards one another to effect a gripping action and away from one another to effect a release action. An electrical motor is arranged to effect such movement, and a battery is connected to supply electrical current to the motor. A capacitor device is also connected to be capable of supplying electrical current to the electrical motor. A control device is arranged to cause the capacitor device to supply electrical current to the electrical motor after supply of electrical current to the electrical motor by the battery, to increase the strength of the gripping action.
