The four measures are:
1. Safety-rated monitored stop
This measure requires that when it is detected that a human has entered the collaborative
workspace, the robot shall be stopped. The stop condition should then be maintained until
the human leaves the workspace.
There are various types of sensing devices that are used to detect a person but among the
most commonly used type in this sort of application are ‘Area Scanners’. These are
‘AOPDDR - Active Opto-electronic Protective Device Responsive to Diffuse Reflection’
2. Hand guiding
In this mode the human can guide the robot at the end effector by hand. Additional
requirements for safety include safe-limited speed monitoring, a local emergency stop, and
the use of an enabling device, which is a three position device that has to be held in the
centre position.
