ABSTRACT:
There is provided by the present invention an optical-electronic rangefin having a housing adapted to be integrated in the gripping arm or mechanism of a robot and housing a light transmitter transmitting a well focussed high intensity light beam, a light receiver having a position detector, a pulse-electronic circuit for controlling the light transmitter and an amplifier circuit for transforming the currents received from the position detector into proportional voltages. The light transmitter and light receiver are so disposed with respect to each other that the central axis of the light transmitter and the optical axis of the light receiver define a predetermined acute angle between each other.
