User Inventor's Guide gives step-by-step instructions
The Vex Robotics Design System (Starter Kit) contains everything you need to design a robot. The creative possibilities are endless. The Starter Kit was inspired by the FIRST (For Inspiration & Recognition of Science & Technology) Robotics Competition--the world's leading high school robotics program. This not-for-profit org. was founded to inspire young people's interest and participation in science and technology.
Note: You will not receive programming documentation with the Starter Kit. The programming documentation section for Inventors Guide comes with the easyC® Programming Kit that is sold separately.
