I have just purchased sames off Alibaba so the price per piece is pretty high. I would like to get the battery, controller and motor down to 100$ so then it would be $400 or $600 for the powertrain costs of the four and six wheeled versions. There is not reason to have a expensive arm board in the initial version so something like a beaglebone black could control the motors. Plus the frame costs. Thanks for the question.
