Watchdog Safety Computer Design and Implementation
R Kilmer, H Mccain, Maris Juberts, Steven Legowik
There are many different aspects of safety to consider when utilizing a robot in an industrial application. In general, however, these can be categorized into the areas of personnel safety and equipment safety. This paper addresses the later category and presents one approach of providing equipment safety through the use of an auxiliary computer to be monitor operations in the workstation. Such a computer system can be used to check robot operations during programming, automatic cycling, and debugging and repair to prevent unwanted conditions from occurring. The basic concepts, design and implementation of such an auxiliary computer on a robot operating in a machining workstation are described here.
