The invention belongs to the technical field of robots. The invention discloses a safety system for a human-machine collaborative environment, where at least one robot and at least one mobile body can work together. The safety system includes a robot information detection unit, a safety partition unit, and a signal lamp unit, warning unit and emergency processing unit; a human-computer cooperation system, and a method for improving the safety of the human-computer cooperation environment. The human-machine cooperation system in the present invention divides the robot working area into sub-areas of different danger levels according to the position and action of the robot, so that the safe area and the dangerous area can be more reasonably divided, and the work efficiency of the robot and the staff in the area can be improved; The human-computer cooperation system in the present invention prompts the change of the dangerous area of the robot through the change of the signal light, prompting the operator to reach the destination through the safe area; the human-computer cooperation method in the present invention can ensure the safety of the robot and the staff Improve production efficiency.
Description
technical field [0001] The present invention relates to the field of robotics technology, in particular to a safety system and a method for human-machine collaboration used in a human-machine collaboration environment. Background technique [0002] Due to the characteristics of its own load and high-speed operation, industrial robots need to set up safety fences around the robot's motion range to separate people and machines and ensure personal safety. However, the safety fence limits the teaching and guidance of the robot in the actual production process of the operator. Therefore, the emergence of collaborative robots enables humans and machines to coexist in the same working area. The current human-machine mode between collaborative robots and humans is a passive defense mechanism. For example, when a person enters a certain area near the robot (usually a A radius circle with the robot as the center) will trigger the robot's defense mechanism, either slow down or stop. ...
