Functional Safety Evaluation Method of Mobile Robot
Mobile robot has been used more and more widely in all walks of life.It brings great convenience to logistics and trans-portation,but also faces new risks brought by robot application,including the collision between robot and human,robot out of control leading to the damage of conveying objects,etc.Therefore,the safety and reliability of robot itself is the premise to ensure its good application.Using functional safety technology to realize the safety protection of robot is the mainstream means in the field of robot safety.Based on the latest functional safety standard of machine application ISO13849,this paper studies the method and process of functional safety evaluation for mobile robot.Focusing on the core evaluation index of performance level(PL),this paper analyzes the evaluation techniques of average dangerous failure interval,diagnostic coverage and category,and combined with the typical robot prototype,the example analysis is carried out.
