Abstract
Abstract A multiple hand controller system is disclosed having redundant systems for synchronizing the movements of the hand controllers. In one embodiment, the hand controller system comprises a pair of movable hand controllers. Each hand controller is coupled to a movable ground point to be movable in two modes. The first mode is where the hand controller moves with respect to its ground point. The second mode is where the hand controller moves as a unit with its ground point. The synchronizing system comprises two sets of components. Each set includes an actuator for varying the location of the ground point of one hand controller. Each set includes a first sensor for sensing the first mode of movement for one hand controller and generating an input signal porportional to this movement. The input signal from the first sensor of each set is fed, through a summing amplifier, to the actuator of the other set. A second sensor is also provided for monitoring the movement of each ground point and generating a signal proportional to this movement. The signal from each second sensor is fed back to the summing amplifier controlling its respective actuator to be algebraically summed with the input signal from the first sensor to generate an output signal. This output signal is fed to the respective actuator to command the actuator to move the ground point location of its connected hand controller an amount representative of the movement of the other hand controller. This cross synchronization enables the movement of one hand controller in the first mode to affect a representative movement of the other hand controller in the second mode.
