An Investigation of Security Approaches in Industrial Robots

Human-robot collaboration is an important direction for the development of the robot industry. In order to ensure that robot can share their workspace with human, the safety mechanism of the robot needs to be considered. Not only to ensure that the robot will not harm the operator, but also to protect the robot itself. We review several related works in the field of human-robot coexistence security methods, including obstacle avoidance and collision detection. Then concerning works of implementation of security approaches in industrial scenario are discussed in detail. Finally, we summarize the problems that have not yet been solved, and hope to inspire new ideals in research of human-robot coexistence security approaches in the future.
