I'm Marge from Haanja. We started this task by drawing the labyrinth and using black tape to make the lines visible. We also decorated the obstacles by drawing different pictures into them. The drawings are mostly related to Haanja.

After that we started making the projects for the robots. It took a really long time because sometimes everything just went wrong. Eventually I managed to make the robot drive through the labyrinth. 

The hardest part was getting it to turn just enough. It kept turning too much or too little. Even now it still turns a bit too much but I used the wall to get it to drive straight. The robot reverses a little and continues driving, now going straight. At least it works :)

Here is the program I made:
