These speeds are inline with human equivalent speeds. ■ Speed and Separation Monitoring. Defines the minimum safety distance between the worker and the robot system to prevent contact between the robot and the human. This can be achieved utilizing safety scanners, light curtains, and operator presence mats. ■ Power, Force, and Torque Limits. Cobots are designed to measure torque at every joint in case of excessive torques or forces, and monitors for sudden impacts, including soft obstructions. ■ Redundant Checking Systems Diagnostics. If the robot detects an anomaly or error at any point, the robot will disable motor power instantly. ■ Safety Rated Stop Modes. Cobots are required to act based on the level of risk. That could be a full emergency stop if a safety mishap has occurred, or it may be a protective stop if a human has entered its operating area. ■ Ergonomic Design. In six axis robots, there are a number of potential pinch points. By designing those joints ergonomically, the worker can avoid injury should their hand, fingers, or even loose clothing get trapped in a joint. With the installation of any robot in a production setting, great care must be taken to ensure a truly safe workspace. This is particularly true in an overlapping workspace that will be shared by humans and their robot counterparts. Consulting a professional installer or integrator will help you to do a full risk assessment and ensure you meet all applicable safety codes and regulations with regards to cobots. Cobots have the ability to reduce worker fatigue, increase production rates, and increase quality, all while reducing waste. In truth, they can be a force multiplier for your production force. In today’s world where we all face labor shortages, increased competition, and high consumer demand, cobots can be an equalizer while creating higher quality jobs.
