Abstract
The mobile hand or mechanical hand is operated by a power system for driving the operative tool, and a sensor device is provided concordantly acting with the power system but having limited power, which is associated with a sight to determine a consensus to the activation of the power system when--in the absence of contrasts due to positioning irregularity of the component to be applied--said sensor device imposes an initial displacement of the same component.
