This question already has an answer here:
I've been thinking about making a species that uses wheels for locomotion. However, instead of using muscle tissue to spin them (as that would cause damage to said tissue), they would use electricity to produce kinetic energy to spin them.
This would work via the use of two protrusions at the end of the legs and would have two points made of conductive materials pointing inwards from the sides of the protrusions. These points will be connected/hold in place the wheels, which will either have a ball-like shape or a standard wheel-like shape made of a spongy rubber-like biological material that acts as a "tire." The two-points would then emit electricity into the wheel to produce kinetic energy/spin, resulting in movement with these wheels.
However, I'm not certain what problems would arise from a species that uses this method, leading me to ask. What problems would arise if a species that uses wheels via electricity/conductivity instead of muscle tissue too move?
EDIT 9/30/19: It's clear to me now that my idea/concept has some glaring problems with it, and I haven't thought as well about it as I thought, and that it needs some serious reworking or needs to be scrapped. Therefore, I will mark this post as answered and/or delete it (whichever the viewers of this post thinks is best). Sorry for any issues or problems I might've caused with this post.
