Fraunhofer Tackles Robots' Dirty Secret: Poor Accuracy

Industrial robots have a precision problem. They're repeatable — put them on the same path and they'll nail it every time. But absolute accuracy? That's a different story. Ask a robot to hit an exact point in space without prior calibration, and things get ugly fast.

Germany's Fraunhofer Institute for Manufacturing Engineering and Automation (IPA) is stepping in to fix this. The research org is developing methods to improve absolute positional accuracy for robotic systems, a critical gap for industries demanding tight tolerances.

The distinction matters. Repeatability means a robot returns to the same spot consistently. Absolute accuracy means it actually reaches the correct coordinates. For applications like aerospace manufacturing or precision machining, the latter is non-negotiable.

Fraunhofer IPA's work could unlock new use cases where robots currently fall short of required precision standards.
