I was just wondering if any Mechanical Engineers could answer me this. You know how cranes and prototype robotic limbs move but at a really slow pace? And when a crane closes its arm, it doesn't do it quickly but really slowly. In the future, will we be able to overcome that limitation and allow contraptions to move at a high speed? Think of you clenching your first or swinging your arm really rapidly, will we be able to build cranes or artificial limbs to do the same thing? Will hydraulics ever become powerful enough to withstand the heaviness of an object? Or is this just something that can't be advanced? Like a physical limitation problem? Will Mobile Suit Gundam robots be possible someday or not?
