According to ISO 10218-2, possible degrees of robot-human cooperation are coexistence, cooperation and collaboration. In coexistence, a robot and a human work in different time periods in a common work area. In joint work, the robot serves as a compensator for gravity or uncomfortable movements.
The robot moves only at the request of the operator, to assist the operator in moving heavier loads and the operator’s work with heavier tools. In collaboration, however, the participating robot, through its design or with the help of accessories, is aware of its surroundings, performs its work autonomously, and can interact with a human in the same way as two humans would cooperate.
