I urge you, and everyone, especially the students I coach in robotics to watch, really watch, how ants move and manipulate their environment. Watch them and consider how many servos and stepper motors you'd need to do anything close.
Watch how the mandibles carry a larvae without harming its soft skin. Watch how she tears a cricket limb for limb with the same jaws.
Watch the way the two tarsal claws adjust allowing her to walk on glass upside down.
