Light tracker tank with 3d printed roller chain tracks.

Link too Demo of light tracking tracked tank. https://youtu.be/loR59x6anaU Link to STL files for roller chain tracks and base. https://www.thingiverse.com/thing:7413811 Here is a link to the video on the Roller chain tracks and base frame that has links to the STL files and other videos on the build. https://youtu.be/38dQspfeEqo This build contains the 2 mount base parts and the light sensor hood cover. All other files can be found in the link above for the roller chain tracks / base. The demo video has links for the electronic parts, but links for things do not last forever so I have also provided images of the light sensors and dual H bridge driver units. I used 4 aa BATTERY HOLDER and a slide switch with 19mm mounting holes.
