In considering the design and testing of a robot workcell that meets these “Collaborative” standards, the
likelihood of an impact to a particular area should be considered. The hand is most likely to be pinched in
any pinch points, whereas the skull is less likely to be pinched as most operators that may be extending
their hands into the workspace will be quite wary of getting their heads between a moving robot and a
hard surface.

Types of Forces
There are four types of forces that should be considered and tested when designing a “Collaborative”
robot workcell. These are:
1.
Clamping/squeezing force.
This is the quasi-static case of the robot pressing a compliant part
of the human body against a surface. This force should be considered when the robot is under
manual control and for
low speed
collisions.
