ABSTRACT:
A three axes controller comprises a support platform in which a first carriage is mounted for movement in a first direction fore and aft of a first neutral position. A second carriage is mounted on the first carriage for movement in the direction of a second axis fore and aft of a second neutral position. A third carriage is mounted on the second carriage for movement in the direction of a third axis fore and aft of a third neutral position. Centering springs are provided for centering each carriage with respect to its neutral position. The first, second and third axes are orthogonally arranged and have a common origin when the carriages are in their neutral positions. A control lever is supported by a gimbal mounted on the first carriage at a point spaced from the proximal and distal ends thereof and a universal joint is provided at the distal end of the control lever for mounting the distal end on the third carriage. The control lever has a longitudinal axis aligned with the first axis when the carriages are in their neutral position and signalling devices are provided which are operative in response to movement of the various carriages to generate a signal proportional to the displacement of the carriages with respect to the member on which they are mounted for movement.
