When it comes to human-robot collaboration (HRC) without separating protective devices, collisions between humans and robots never really be ruled out. Consequently, the permissible limit values according to ISO/TS 15066 for force and pressure must be observed. These regulations ensure the safe operation of collaborative robots (cobots) in the workplace. With regard to occupational safety, different requirements arise for workspaces employing cobots. Collision prevention and detection, torque monitoring and force limitation must achieve a similar level of protection as separating safety fences. The GTE CoboSafe force-pressure measuring system is an easy-to-use instrument for demonstrating compliance with required limit values. As required, a set of force transducers can be assembled with up to nine devices, each equipped with different spring constants. The combination of spring constant and additional damping element enables measurement of the biomechanical limit values in accordance with ISO/TS 15066, DGUV "FB HM-080," and "RIA TR R15.806-2018" (as specified by the Robotic Industries Association of the American National Standards Institute). As a component for pressure measurement itself, it is a simple set based on pressure measurement foils.
A more sophisticated pressure measurement method based on electronic foil sensors is also available.
