This hand has no skin on it - lacks ability to fixate target while slightly touching it and in some moments it’s frustrating to see how it tries to roll that dice a bit but it just slips left and right.
Robots deserve skin. And might be something fleshy under it. Metal and plastic is too slippery even for a human to operate with.
That would help increas dexterity in that kind of operation. But engineers won’t be able to do anything with a hand without removing that cover first, that’s why they might not make it.
Same problem with cheep artificial limbs, especially hands, every model I saw had not got any rubberized cover on it, except really few and expensive ones. While most of them have a really good motion detection system and can be operated (after certain training) easily, has relally smooth limb movements and allow all movements a real limb capable of.
