We are seeing more and more users getting started with cobots, we look at the market reports, and everything suggests that cobots are becoming more and more popular.
Some people think that their high safety limits are actually stopping new users from getting on board with this technology.
The researchers start their paper by declaring: 'The authors of this paper believe that one reason for [the] slow uptake [of cobots] is due to the high requirements on the safety and the lack of engineering tools for analyzing collaborative robotics applications.'
The researchers defined 'slow uptake' as being 'relatively few collaborative robots in industrial applications compared to standard industrial robots.'
The team proposes that a systems engineering framework and dedicated engineering tools could be a better way to analyze the risk of collaborative robots for specific applications.
For example, the maximum force a cobot can apply is defined from the 'onset of pain' rather than the 'onset of injury' which Esben thinks would be more reasonable.
Some performance factors which are hindered by the robot's safety limits are: All three of these restrictions can be removed or reduced by varying the safety limits of the robot.
However, as the European researchers explored, we will be able to improve cobot performance once we have a better way to set these safety limits for the needs of specific tasks.
If we were to remove the safety limits completely, this would make them exactly the same as traditional industrial robots… and that implies using cages, advanced sensors, or other safety measures.
Over time, our industry will improve the way we define safety levels, perhaps incorporating similar risk analysis methods as those that were outlined by the European researchers.
