Name this device

    This device was in a documentary on Discovery last year. At least that I can recall.
    Does it have a name?

    The idea seems very much like a pantograph such as here:

    but the illustration with the differential gearbox is of a much more sophisticated device, which probably has a distinct name.

    Thank you very much yes, that exactly what it is.
    There is no differential gearbox. I misunderstood the whole device and its principle of operation. :D

    Thanks again.
