A joystick control system includes a first pair and a second pair of fluid
enclosed resilient tubes with each pair of tubes having generally
parallel spaced pressure sensing portions confined within a support
housing with one pair of sensing portions disposed perpendicular to the
other pair of sensing portions. A control stick extends between the
spaced sensing portions of both pairs of tubes and is supported for
slight lateral or universal tilting movement. Each pair of tubes is
connected to a corresponding sensing transducer which varies electrical
output signals according to the pressure applied to the sensing portions
of the tubes by the control stick.
