Today’s collaborative robots are intrinsically safe since they have power and energy limitation in case of collision. But they need a collision to detect the presence of a person and stop. Normally, a restart is needed. Our project has developed a detection system to get the posture of the person (detecting hand, arm, head, body positions, legs) using a TOF camera and constructing a point cloud. It gets the real time robot position, calculates the robot space occupation and compares it against the person position.  System calculates the 3D distance between the closest points between robot and person. System generates a corrective action (stop, direction change or slow down), before collision can occur. System resumes normal operation automatically after the risk disappears. User can define the controlled area, usually shared area between robot and person.
