We finished our mission/course!
In our first run we had some difficulties with the hardware, our rover was not able to drive backwards. After we repaired the mechanical part we gave it another shot.
It turned out that we did not receive any coordinates, so even not 0,0. Thus there was no communication from the earth computer to our rover. This resulted in the zigzag mode, the mode which is performed when there is no communication.
For people who are interested, our code is posted here and the description is in our previous posts. Now we just have to wait for our final mark.
