You suggest that gripping a ball could be more specialized than gripping an apple depending on the factory context, but manipulating an apple requires more finesse and adaptation. Think of it like managing a simple form versus a complex file where each piece is unique; the apple demands pressure detection to avoid crushing it. A robot that can pick an apple without damaging it, as in fruit harvesting, has a more sophisticated capability because it must handle irregular shapes and fragility. Gripping a ball is often more standardized.
