i have had an idea about the wheels.
in the manga there seems to be mechanisms inside the wheels and i have had a little idea.
By using a "Two Pole DC Electric Motor" inside the wheel, you are able to generate rotation.
A "Two Pole DC Electric Motor" is meant to rotate anyway but by putting it inside the wheel i thought it could increase the speed of the ATs
by using an electromagnet as the Field Magnet it increases the speed but the set back there is electromagnets drain the power out of the power supply very quickly.
my reference for the motion:
