How to find enemies

After we built the rotating base we moved on to the mechanism that will support the RGB sensor to search for the enemies. We chose the RGB sensor because, as we were told, it is the most reliable sensor. Therefore our first attempt to find the enemies will be with it. We could use the touch sensor, but there are three different types enemies and it would make it hard to know which one it would be touching. We decided to do a stretchable structure so it does not occupy too much space and makes it easier to handle.

This is our first try and it looks like it can handle the job! We will do further tests so we are able to figure out whether the RGB sensor is the most suited.
