It is true that an architecture like that of the Festo Bionic Handling Assistant can certainly improve the dexterity and adaptability of a robotic system for object manipulation.
However, the reduction of fragmentation within robotic vision systems seems more related to the harmonization of communication protocols and standardization of software interfaces.
For a vision system to work uniformly, it is prudent that sensors and image processing algorithms can exchange information smoothly.
For example, the implementation of middlewares like ROS is often more decisive for integrating software components than the mechanical design of the arm itself.
