Hi David
I think that's when its time to splash the cash-regarding drive train/motors and
speed controllers, I cant see me picking up sprockets and chains at a car boot
sale or speed controllers and motors in a skip.
At some point Adam and myself were going to put a call out for a complete
set up,we are still at quite early stages but if anyone has a full system-ie
speed controller/motor/drive system WHY at a second hand price,get in touch.
Because the wheels are large on our robot I'm probably looking at a drive ratio
5 to 1 minimum.
May even consider buying complete robot-not to dismantle but to share a similar
drive system.
