KITT: a Line Following Robot

The purpose of this project is to develop an autonomous-line following vehicle for robotics/transport purposes. The vehicle may be used as a general robotics platform onto which other electronics may be added or explored.

KITT uses 5 IR sensors to detect the position of the line. It is driven using two geared DC motors, with a swiveling caster wheel in the front. The system is powered using 8 AA batteries.

This project was a joint effort with myself andAndrew Prata.

The robot uses commonly available components online and in school maker spaces.
