The idea that a robotic arm, even with a sophisticated design like Festo's Bionic Handling Assistant, can alone reduce fragmentation in vision systems is an illusion of PnL.
Mechanical flexibility doesn't fix issues of non-homogeneous data or algorithm errors which are the real causes of fragmentation.
A client pays for the overall performance of a system, not for an arm that looks good.
If the machine can't reliably identify a part because of a software limitation, no matter how flexible its movement, it's a loss.
In our factory, if the line stops because robotic vision can't distinguish two shades of blue, the fault is software, not mechanical.
