This project was built for the Things that Think undergraduate/graduate class CSCI 4830-7 and CSCI 7000-7 for the University of Colorado at Boulder. Our group consisted of one graduate and two undergraduate students. We worked on the project for 8 weeks, most of the time trying to learn how to program the arduino and learning the basics of circuits. If you are looking to build this project, we do not anticipate this project taking nearly as long, but altogether could be completed in one weekend.
The purpose of this instructable is to outline our development of this robot snake as well as provide instructions and tips for future engineers hoping to complete a similar project or use components of our project in theirs. The goal of this project was to create an automaton snake that reacted to its environment. The main functionality of the snake is for it to follow a light source. Some goals we had in conjunction to the movement of the snake was to have a tail that rattles and decorative LED lighting. This tutorial will start with a little background information, then show the development of the basic pieces, and finish by finalizing your design.
