  • Patent number: 5771181
    Abstract: A system for producing realistic tactile feedback forces in a tool operation simulator. Sensors sense the location and direction of movement of a simulated tool in a simulated landscape environment to produce electrical signals representing three dimensional location and direction of movement. These electrical signals are processed by re-programmable processors to produce control signals that are fed to pneumatic bi-directional piston-type actuators to impart realistic forces similar to forces that would be encountered in corresponding real-life movement of the simulated tool.
