Robo-Mate has tested its three modules in ZHAW's labs in Winterthur, Switzerland. The lab tests serve a twofold purpose: First, results can be used to adjust either the prototype or the testing plan for the tests in real industrial scenarios. Second, in a controlled environment engineers can include a number of measurements that they could not include in an industrial scenario (for example with EMG, force plate, and video recording).
Robo-Mate's passive arm module does not need any power supply, is lightweight and provides a constant supporting force that can be easily varied. In a recently published paper, Ruprecht Altenburger, Daniel Scherly and Konrad Stadler (all from ZHAW) describe the requirements, design and geometry of the module, including a tiny little detail that makes a big difference.
