The role of computers in achieving hazard control of industrial robot operations was assessed. Development of robot related safety measures is the responsibility of robot builders and suppliers, employers and employees. Hazard control is principally at the design level and hazard prevention at the robot selection level. Operational constraints are related to design limitations and performance deteriorations. An understanding of the significance of robot safety concerns has permitted the assignment of priorities based on systematic risk evaluations. Safety measures described included computerized system interlocks, intrusion detection schemes and emergency stop provisions. Computer control of robot manipulators requires external task instruction, internal closed loop operation, and system sensory feedback. Closed loop architectures involve hierarchial partitioning of the command feedback into multilevel modules with layered decomposition of task instruction and layered extraction of sensory feedback. The importance of developing built in computerized fault detection systems and diagnostic programs for shutdowns was addressed.
