About this model

Demo Video can be found here. Build video link. Here is a link to pictures and text on how to build the Light tracker on the Alphadrome web site. Using two low-cost light sensors and a dual H bridge motor driver you can make robot that will follow a bright LED flashlight position. The front motor driven wheel will rotate to aim towards the source of the light. Two TT gearmotors 1:48 are used. Four AA battery's supply the 6-volt power. I used 6-32 screws of various Lenths, they will self-thread into the 3d printed parts and the TT gearmotor.
