The mechanical flexibility of a robotic arm like Festo's does not guarantee a reduction in the internal fragmentation of vision systems if the actual P&L does not follow.
You can have a very flexible arm, but if the cost of integration and maintenance of a complex vision system outweighs the gains of this flexibility, the net benefit is negative.
In Switzerland, we look at the final invoice and operational efficiency; if the implementation costs weeks of engineers' work at 200 CHF per hour, flexibility becomes a sinkhole.
The only relevant criterion is what brings tangible benefits, not just technical elegance.
