Well with the tools it was really $150, I also didn't skimp on anything and bought the best of the options provided for all the stuff. This will be my first attempt at building a robot, I've worked on programmer bots before when I was doing my Masters in IT at RPI. This however will be my first home grown attempt.
Question though, is there another material that is recommended to be used for beginner wheels besides cardboard? I want something a bit stronger in case my dog takes a swipe at it (and cardboard just doesn't look cool)...
