Safety Zone and Its Utilization in Collision Avoidance Control of Industrial Robot

With the development of the digital economy, small-batch customized production has been increasing, leading to a growing application of industrial robots. In these scenarios, new situations arise due to increased debugging frequency and insufficient expertise of debugging personnel. This often results in human errors during actual operation and debugging, leading to control parameters exceeding the safe range. As a consequence, collisions occur between industrial robots and workpieces, causing severe damage to both the equipment and the samples. Through the study of safety zones and robot collision avoidance systems, we propose an effective method – the concept of a virtual safety zone, without the need for additional external equipment or increased investments. This approach ensures a dual layer of safety between the robot and the samples, reducing the risk of collisions, easing the operator’s tasks, and enhancing the likelihood of safe robot operations and successful debugging.
