 Build your own robot with this basic do-it-yourself       Tornado Bot package. It's easy and fun, do it with your friends!  

The Tornado Bot is a solar powered spinning top mounted on a plexiglass disk (neon colour choices available). It comes with a magnetic vertical mount that lets you hang it from any metal surface close to a light source. The capacitors allow the Tornado Bot to charge quickly and discharge with a buzzing sound (buzzer included). 

The Tornado Bot can be mounted almost anywhere, outside, on the dashboard of the car, in an office by the window. It is easy to build and fun to watch it work. Get several so you can upgrade them all to combat bots! 

The basic Tornado Bot can be upgraded to 3 other Combat robots, the Side Winder, Transform 360 and Hammer Throw using the Combat Up-Grade Packages available on the website.

Build them all and watch them fight, compete with your friends!!!


How it works

The Tornado Bot series of robots work by generating electrical power through a solar engine circuit that you built on the back of the Brainchild Solar Panel. By converting light energy (from any available light source) into electrical energy and storing it in a capacitor until it reaches and threshold voltage. The electrical energy is converted to mechanical energy as it is released to the motor to spin the Tornado Bot . (See technical Data in the download section.) In direct sunlight the Tornado Bot runs continuously. 

Complete instructions are included.
