Here is the final code that we used to run our robot.

There was more to the robot than the cardboard and motors mentioned before in the blog. The wheels attached to the motors are from a lego kit, they are attached with hot glue. The cardboard body of the robot is held together with zip ties (we would have used nuts and bolts to hold it but we were attempting to keep the robot as light weight as possible) and everything else comes straight out of the arduino kit we we purchased at the begining of the semester.

Here are the final images of our project all put together. The wires are all "hidden" between the two cardboard bases along with the arduino, breadboard, and the sensor is hiding at the bottom just above the ground. And, of course, why have a girl on the team if she isn't going to put a cute image on the robot? Meow!

This video shows that despite the motors not being strong enough to push the whole robot, the project does what we wanted it to. The sensor properly works and the wheels move depending on what the sensor is reading. If the motors had enough torque, the robot would follow a drawn line without going off track.

This video shows that our motors properly work. However, it is only barely moving because we do not have enough torque on the wheels in order to move the robot.

There are the parts done using Solidworks to be laser-cut. We will be cutting it out on 1/8" cardboard. These are much improved from our self'cutouts of the bases of the project. 

In theory, changing which motor spins based on what color is underneath the sensor, the robot should be able to move itself along a drawn path.
