Force and pressure measurement systems for checking transient and quasi-static forces and pressures on collaborating robots
Force and Pressure Measurement System
When companies use human-robot collaboration (HRC) in their workplaces, they must carry out a risk assessment and periodically check the system. One element in the risk assessment is the potential collision between the robot and a person. CoboSafe is a force and pressure measurement system for inspecting transient and quasi-static forces and pressures on collaborative robots. The easy-to-use system has a modular design and includes force measuring devices, a pressure measurement set and evaluation software to verify compliance with required limit values. A set of several force gauges and pressure measurement sets can be combined as desired.
Human-robot collaboration (HRC) establishes itself wherever the robot as assistant promises more flexibility, reliability and economic efficiency. There is a steadily growing market with more and more possible applications. The collaboration between humans and robots is so efficient because there are no fences, safety areas or monitored zones that restrict effective work. For this reason, however, collisions between robots and people cannot be ruled out. To protect people, the collisions must not be painful or even lead to injuries. Therefore, pain thresholds were determined in a study and defined in standards as limit values for collision forces and pressures.
The CoboSafe force and pressure measuring system can easily and precisely determine the collision values on site and in practice. The measurements must be made on the application, as simulation is not possible. The development of the CoboSafe measuring devices was therefore based on practice. The result is force gauges with the smallest dimensions and low weight, which are therefore very easy to position. With them, users are mobile and ready to take measurements immediately.
