In order to determine the safety method for human-computer cooperation application, the International Organization for Standardization ISO/TC 184/SC2 WG3 has accepted the entrustment and prepared the ISO/TS? The 15066 technical specification "Robots and robot equipment - cooperative industrial robots", therefore, if you want to become a cooperative robot, you need to meet the safety requirements of ISO/TS 15066.
First, security level monitoring stops. When someone enters the test area, the robot must stop working. The second is manual guidance. The cooperative robot can only work according to the touch force of the operator. The third is speed and separation monitoring. A robot can only work when there is a certain distance between it and a person. The fourth is that the power and power are limited by the controller and built-in design. When a touch accident occurs, the robot must reduce the output power to prevent the accident. The cooperative robot needs to meet at least one of them, and when the robot is in working state, there must be state indication. Only when these requirements are met can it be called a cooperative robot.
All these requirements are related to safety performance. It can be seen that safety is the most important point for cooperative robots. So why do we use cooperative robots? What are the advantages of cooperative robots?
First, reduce costs. Since there is no need to install a safety barrier, it can be placed at any position in the factory and can be adjusted at will.
Second, debugging is simple. No professional knowledge is required, just simply move the body of the robot for teaching.
Third, reduce safety accidents. Compared with industrial robots, cooperative robots are easier to control.
These are determined by their structural characteristics.
First is its torque sensor. The cooperative robot has six torque sensors, which can detect collisions and ensure safety, and make the robot move more accurately.
The second is the installation position of the servo drive module. The servo drive module controls the mobile robot through current. The servo drive module of industrial robot is generally installed in the control cabinet, while the cooperative robot is installed at each joint of it. By double calculating the position value of the robot, the cooperative robot is more accurate and safe than the industrial robot.
