Solarbotics' SolarSpeeder v2 Kit is a very quick Solaroller that can cover 3 meters (10 feet) in under 40 seconds in direct sunlight. This is a fun beginner kit with easy to understand electronics and does not require programming or complicated microcontrollers.
The SolarSpeeder has a strong heritage in Solaroller racing. Solaroller racing has two solar-powered cars race side-by-side down a one meter (3.3 foot) track. Early in the history of Solaroller racing, the one-meter times were in the 10 and 20 minute range, but as electronics improved and mechanics got more efficient, the elapsed times dropped to 6 minutes, then 2 minutes, until now they complete the meter in less than 20 seconds!
Now updated with MillerEngine Technnology! So what does that mean? It means a big improvement in performance at not increase in complexity or cost! Simple to construct and a blast to watch in the sunlight!
