The SolarSpeeder 2 Kit is a very quick Solaroller that can cover 3 meters (10 feet) in under 40 seconds in direct sunlight.
This new version of the Photopopper is still a solar-powered, light-seeking, obstacle-avoiding robot, but now with update electronics & gold trim that make it twice as fast!
Our demobot shown built with GM3 motors (since replaced with GM2) on an Sintra base (extra).
These aren't kits, as much as they are an inexpensive bag of components so you can build yourself a Symet.
Herbie the Mousebot is a very quick, easy-to-build, light-chasing robot kit with functional whisker and tail sensors!
This epoxy-encapsulated monocrystalline solar cell generates a nominal 4.5V / 18mA (sunlight) from a 24x33mm package. And has an integrated solarengine circuit board!
This epoxy-encapsulated monocrystalline solar cell offers 6.7V and 20mA in a 37x33mm package. Now updated with the Miller Engine circuit!
This big brother of the SCC3733 is also an epoxy-encapsulated monocrystalline solar cell, but this one offers 8 volts and 44mA in a 37 x 66mm package!
This is the printed circuit board (PCB) for the main project in the book 'Robot Building for Beginners', by David Cook.
