Abstract

In the typewriter keyboard tester, key button testing, point plotting and data interpretation by manual methods were too slow and subject to human introduced errors. Automation of the test and analysis removed the errors and increased productivity. The automatic tester combines a robot system, special fixtures, special hardware logic, a processor, an RLC bridge, and a special linear actuator. The basic system is shown in the figure, which is keyed to the description that follows. The AML (Advanced Manufacturing Language) application 10 provides arm positioning linear actuator commands, test commands, retrieval of test data, logging of test data, and real-time evaluation of test data. The command and control unit 12 contains unique hardware to interface between the robot system 13 and the other units within the system.
