A high percentage of robot-related accidents occur during maintenance and application development. Conventional safety systems, such as barriers, light fences, and pressure mats, are incapable of providing protection during periods of unstructured interaction between people and robots. A safety monitoring and control system is described that accommodates close human interaction with one or more robots and yet prevents 'run away' robots, collisions with intruders, and collisions among objects within the workcell. These result from programming errors, controller malfunctions, and/or human misjudgement. Presented is an overview of the monitoring system, the controller architecture, and an example of a safety algorithm.
