Stating that the BionicMobileAssistant is just a subcategory of the Bionic Handling Assistant, as if it were a simple specification, ignores the major functional break brought by autonomous mobility.
Who benefits from this simplification that reduces a mobile system capable of navigating alone to a simple variant of a robotic arm?
A manipulation arm, even precise, remains static or limited to a base, whereas the mobile must handle navigation and obstacles, which is another ball game.
This classification seems more aimed at grouping innovations under an existing banner, for marketing reasons for example, than reflecting a true stable technical hierarchy.
It's like saying a delivery drone is just an improved basket – the movement capability changes everything, from risks to applications.
