Tube Runner

Tube runner is an attempt to create universal extensible remotely controlled vehicles. It's designed to be very symmetric and easily printable.
Simple tube plate - it's a default dummy plate for robot, but feel free to replace it with extension, like: camera, proximity sensor or additional battery pack.
This project doesn’t explicitly specify electronics requirements, but if you want to use arduino - feel free to use RC Controller https://zzbot.org/projects/remote-controller/
