The Robot Duo offers a great price for purchasing Bee-Bot and Pro-Bot together. This fun robot combination offers a learning continuum across the age spectrum from kindergarten on up. Easy-to-use Bee-Bot, targeted at children from 5 to 8 years old, provides a fun experience in basic control and programming with immediate feedback. Pro-Bot builds on this experience for children from 8 years old and up, by expanding the experience to include setting angles and distance, creating longer and more complex programs, and creating and incorporating sub-procedures into the commands. Pro-Bot can draw as it moves and touch, sound, and light sensors encourage experimentation and keep students of any age engaged. The Robot Duo is perfect for a multi-child household or any environment with students of different ages, experience, and abilities.
