Such actuator design specifics aren’t relevant to my point. If you want to move a large distance, powered by energy from a chemical reaction, you have to diffuse to the target point, then use the chemical energy to ratchet the position. That’s how kinesin works. A chemical reaction doesn’t smoothly provide force along a range of movement. Thus, larger movements per reaction take longer.
