Title:
JOYSTICK CONTROLLER
Document Type and Number:
Japanese Patent JPH0438507
Kind Code:
A
Abstract:
PURPOSE:To enable the feedback of force and to realize versatility by outputting the control signal of a rotational torque by operating a commanded torque to a motor based on a command from a target device and a detection signal from a rotational angle detecting means. CONSTITUTION:When feeding back tensile strength to a joystick 18, first of all, data such as a mode setting command or the value of force feedback are fetched from a target device 38 through a communication table 42. Further, the potentio-angle of the joystick 18 is inputted from rotational angle detectors 30x and 30y of a stick manipulation part 10. Next, when a CPU 34 reads out a program from a memory 36 and operates an output torque, a controller 12 calculates the commanded value of a traveling position for a traveling object in the target device 38. This output torque is outputted through a D/A converter 44 to a current control amplifier 46 and on the other hand, the commanded value of the position is outputted through an RS232C interface 40 to the target device 38.
