   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.
