The idea that the BionicMobileAssistant would be a sub-category of the Festo Bionic Handling Assistant makes me seriously skeptical.
The Bionic Handling Assistant is a fixed arm, period, and the MobileAssistant is clearly designed to move and navigate, which is a fundamental difference.
It's like saying a wheelbarrow is just a variant of a wheel, ignoring the tray and handles.
Who benefits from simplifying the distinction between these two systems, and what is the motive behind this classification that ignores mobility as an incentive for difference?
