Virtual operating unit for microprocessor-controlled devices

Abstract

A personal computer or equivalent is programmed to create a virtual operating unit for a robotic device (eg., a micro-processor controlled machine, conveyor, etc.). The actual operating unit, which plugs into the robotic device and controls it, includes a keypad and a display. When reprogramming the machine, the operating unit is unplugged and the computer is plugged in. The computer can be switched between two modes. In a programming mode, the computer is used to modify the program in the robotic device microprocessor. In an operating mode, the computer mimics the operating unit to test the newly-entered program. On the computer screen are generated a virtual display (the image of the actual display of the operating unit) and a map of the operating unit keypad. The technician observes the virtual display on the computer screen and enters commands, indirectly, through the computer's keyboard instead of through the actual operating unit keypad. The virtual operating unit allows the robotic device program to be tested without disconnecting the personal computer and re-connecting the actual operating unit. The virtual keys may be highlighted, as by flashing, when the corresponding keys of the computer keyboard are touched.
