 ### Setup & Approach
 
-In the first experiment with the color sensor we continue to use the robot we built for the first experiments, but exchanging the sensor. For further experiments, we will try to change the physical properties of the robot, by replicating the lower part of the robot, shown in the video above. I.e., we will follow the [building instructions](http://www.nxtprograms.com/NXT2/segway/steps.html) up to and including step 7 [7]. Below we see three images of Philippe Hubrain's robot with the Color Sensor, and three images of our NXT Segway.

However, we will not be interlocking the wheels, since our PID applies different levels of power to each engine. Conclusively, they have to be able to run independantly. In addition, we added some minor pieces to the sensor mount, to increase stability and even out the weight distribution slightly.
