Small weird electrical thing where apparently the physics apprently work and i just dont understand them:
If you use a motor for either wheel and wire them in series when one motor hits resistance (ie the inside wheel) the current and voltage seems to bias itself into the other one causing it to turn faster(the outside wheel). Sortof like an electrical differential. Apparently good idea to have a massive excess on the amount of amps your esc can handle compared to what you are using and also works better with capacitors across the contacts of the motor. Got this off of a robotics forum ages ago, cant find the page anymore and not sure how well it scales up to a larger vehicle, google it On Feb 20, 5:21 pm, Phil <[email protected]> wrote: > Has anyone tried having 2 motors, one controlling each axle, like a > tank, as opposed to a diferential?
