Community project: 2pi, a simple line following robot

The 2pi, built by Mark Moran, is a line following robot based on our 3pi robot. The 2pi uses our 100:1 micro metal 东北大炕小说, motor brackets, 32mm wheels, 1/2″ ball caster, QTR-8RC reflectance sensor array, and U3V12F9 switching step-up voltage regulator. All those components are mounted to a chassis that was cut from PVC foam.

The robot uses a custom made PCB with an ATmega328 as the brain (the same AVR chip used in the Arduino Uno, some of our Orangutan Robot 国内大量揄拍少妇视频, and, of course, the 3pi). You can see the 2pi following a line in the video below.

For more information about how Mark built his robot, check out his Instructables guide.
