Three-wheeled electric mountainboard *in progress*
My electrical engineer neighbor gave me six 12v led acid batteris- YAY! These will most likely end up in a sumo robot for next years National Robotics Challenge, but I was hasty to find something to do with these using the materials I have now. I had scavenged a broken electric dirtbike months before, and decided to build an electic mountainboard using that rear drive wheel and the six batteries. I made a front truck using a block of aluminum, steel rod, and wood. The rest is extremely simple, my curent control mechanism is simply a button you push to go- its either off or full speed. This makes getting started difficult without being thrown to the concrete.
Anyway- soon I will put a video, a better explination, and some pictures up. In the meantime, how could I make a control mechanism that allowed for variable speed? any ideas? Right now I rapidly press and release the go button to get started smoothly, but I imagine this rapid on-off-on-off puts extra stress on my motor.
