The closer man and machine work together, the more efficient work practices become. However, safe interaction between human and robot increasingly demands new technologies and solutions. Also, the demands on safety increase, the closer human and machine get to each other.
To verify the required safety level, the entire safety function must be considered – from the sensor to the logic and beyond to the actuator. Safe human-robot collaboration (HRC) can only be guaranteed when all these factors interact in a co-ordinated manner.
