It turns out that the treads I was using are way to heavy/bulky so I decided to just scrap the tankbot idea for now and go with a simpler bot  I am using two GM9 (143:1 90 Degree Shaft) and wheels,  a Pololu micro dual serial motor controller, a Hs-311 standard servo, and a parallax ping))) ultrasonic sensor.

  Ive got almost everything done, but I am going to need some help with the motor controller .

Here is my attempt at an arduino tankbot  this is going to take me a while to complete because I am a little tight on money for now but I am slowly savin up, first for the motors/gearboxes, then for some sensors.

I also have to get better at codeing too :P
