Robots have bearings and simple, efficient rotary electric motors. A machinists lathe is a fantastic piece of technology. We're really good at building things that rotate.
Nature uses cellular-scale nanotechnology to build millions of microscopic linear motors. We can build linear electric motors by essentially unrolling the stator, but they're on a much larger scale.
We get better results with servomotors, either installed with some gear reduction at a pivot joint, or hooked to a ballscrew linear actuator.
