So you want to get mobile with your Arduino or other micro controller, and you aren't sure where to start? This 4WD robotic platform is a great start! The kit includes four geared motors, four rims with tires, and a high-strength aluminum alloy body with mounting holes. It can traverse grass, gravel, sand, or sloped surface with ease. Just add an Arduino, or other microcontroller, motorshield, and power supply and you ready to get going! We recommend the Romeo microcontroller, for it has built in motor control and additional buttons.
