"DESCRIPTION: The QuadCrawler robot is built on a high-quality aluminum chassis that provides a sleek platform for the 8 servo motors and BS2/BOE based control system. The kit allows you to get started with this list of materials, including the BASIC Stamp® 2 microcontroller, Board of Education® carrier board, 8 Hitec servos, and 1 Parallax Servo Controller. Mounting holes and slots may be used to add custom robotics equipment. The QuadCrawler circuits are built on the Board of Education carrier board. With additional accessories in our Robot Component Shop and Accessories pages, the QuadCrawler robot may be programmed to perform all sorts of neat movements. The detailed manual gets you started with a number of complete programs. Once you have mastered the supplied code, you can easily customize it using your own programming creativity. Please note: The kit is not complete, since you are required to supply hand tools, a 6 cell battery pack, and a 9V battery (not included).
