 ## Self-balancing robots with color sensor
+
+In this section we will try to use a color sensor instead of the light sensor, as proposed by the NXT Segway with Rider design [6]. We hope to achieve similar results as show in this video: [NXT Segway with Leaning Pilot](https://www.youtube.com/watch?v=q9ZONn3p1LI). 
+
 ### 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].
