Our project partner angsa’s robot can remove cigarette butts and bottle caps from green spaces fully automatically. But how well and efficiently can it do this? Does it pose a potential risk to children and do passers-by feel comfortable in the presence of the robot? The requirements for robots in public spaces are diverse - but have so far only been very vaguely outlined. Together with the RimA accompanying research project, the rokit consortium led by HFC is therefore working on tangible metrics to evaluate commercial service robots. To test the metrics, the cleaning robot was subjected to a series of tough tests at our project partner Fraunhofer IPA in Stuttgart at the beginning of November. For example, the force exerted on a human being was measured if a collision were to occur due to failing safety functions. The good news: everything was in the green. The test of interaction quality, which essentially consisted of 15 scientists trying to push the machine to its design limits, was particularly enjoyable. There was no final assessment for the robot, as the event was initially used to evaluate the applicability of the metrics. The test catalogue will now be revised again until the test in the real environment is due to take place in April.
