### Self balancing robot with light sensor ### Self balancing robot with light sensor
We start by running the initial program provided by [2]. This didn't give a good result. Frej just rushes in either direction and never stands still. The only reason that Frej is able to keep upright and move about is that he has tilted to the side that his light sensor is one, causing him to rest on the sensor.

The light was on. The light was on.
The light sensor returns very different measurements of different colors, and the bathroom floor has lots of colors (see picture). Therefore we tried the big black thing which gives a completely different setting. Both the color of the surface (which is now black instead of blue-ish) and the consistency in the color (completely black instead of different blue-ish colors) and how even the surface is, as the black thing is very uneven.
