This is my second rover, complete from scratch... tho its not entirely working smoothly.
Its made of paddle pop sticks, water bottle caps for the back wheels, and the chassis of a $5 barbie toy car... along with servos, arduino, sensors and a camera mount.
I replaced barbies car motor with a hacked 3003 servo, but its acting a little weird... hence the running issues. Will up date with a video soon. Just pics for now
