Send your robots right over!
Are you a Science, Technology, Engineering, Art, or Math teacher? Or teacher of another discipline that is looking for a way to incorporate STEM / STEAM into your curriculum?
You don’t have to be a teacher… hacker, hobbyist, professional, casual learner, etc. will do just fine.
Meet “Red Rover“, an inexpensive autonomous rover that anyone, age 8 and up, can build! It’s comprised of a few 3D printed parts, easily-sourced hardware, and a tiny Atmel microcontroller. When you’re ready, you can upgrade the microcontroller to an Arduino Mini or Arduino UNO. The design is expandable and highly configurable.
- * Servo Modification and Control
- * Electronics Engineering
- * Mechanical Engineering and Assembly
- * Arduino Programming (C)
- * Obstacle Avoidance / Navigation
- * Sensor Interaction
- * 3D Modeling
- * 3D Printing
Purchasing parts in quantities of five, ten, and twenty dramatically lower prices – cost per-student can be as low as $20. Parental supervision is always a good idea for young roboticists!
