Boe-Bot Robot : Great Basic stamp programming flexibility

What makes the Boe-Bot great is the BASIC Stamp microcontroller’s flexibility of programming when coupled with breadboard circuit construction. Following along in Robotics with the Boe-Bot, users quickly learn about embedded projects, from wiring and components to programming and mechanical dependencies. The kit includes a set of passive components (wires, resistors, capacitors), sensors (photoresistors, bumpers, infrared sensors) and hardware (whisker touch-sensor kit) to complete the different projects.

The Boe-Bot robot takes about 1-2 hours to put together, though each project in the Robotics text provides a unique new experience of wiring and source code tuning. Completing the entire set of projects takes 50 hours and is suitable for anybody over 12 years of age. The Board of Education (and BS2-IC) may also be removed to be used as your platform for the other kits in the Stamps in Class series
