ABSTRACT:
An X-Y controller (10) includes a first part (12) that is spherically guided by a second part (20). First and second shafts (26) of first and second transducers (24) are secured to the spherically guided first part (12). First and second levers (54) are mounted to first and second bodies (28) of the first and second transducers (24). The levers (54) each include a slot (58) which engages a respective one of first and second pins (60) that are inserted into the second part (20). In response to a first one of the mechanical inputs (X or Y), both of the shafts (26) of the transducers (24) are rotationally positioned proportional to the first mechanical input. In response to the second one of the mechanical inputs (Y or X), both of the potentiometers (24) are rotationally positioned about the other axis (Y or X); and the levers (54) and the pins (60) cooperate to rotationally position the bodies of both transducers (24 ) proportional to the second mechanical input (Y or X). Optionally, by locating the pins (60) at various distances (76, 78, or 80) from the transducers (24), proportionality is changed with respect to one of the mechanical inputs (X or Y).
