### Self balancing robot with light sensor
---
We started out by rebuilding the robot with respect to the building instructions in [2].
We started by running Bagnall's program [2] without modifications, in the large working space in the Zuse building. This didn't give a good result: The robot just rushed ahead, either upright or sliding around on its "back", never holding its balance and standing still. The only reason that the robot was sometimes able to keep upright was that when tilting forwards, it landed on its light sensor which then held up the robot like a crutch (as seen in Video 1).
