Abstract
The device is intended to be used for recording the position reached by a moving part, such as the arm of an industrial robot moved by a rotary motor (M). The device comprises, in an assembly capable of being associated with the said moving part, an angular-position transducer such as a resolver (2), capable of generating at least one signal (4, 5) indicating the position reached by the motor (M) during a rotation, counting means (12) connected to the angular-position transducer (2), capable of storing a cumulative count of the signal generated by the transducer (2) itself and indicating the position reached by the moving part, and power supply means such as a buffer battery (18) capable of keeping the position transducer (2) and the counting means (12) active even when there is no external power supply.
