Task 3: Fresh Air to the Classrooms
Embedded Files
This was a more scientific task. You have to think before the coding and especially the ultrasonic sensor with the 3m limit was a complicated obstacle for many teams. Also the height measurement created a nightmare for others. This time we received overall 16 smart solutions and welcomed one new team! Below you can find the winners solutions and also the complete team results after the two rounds of the competition.
GbeProBot
GbeProBot
Team GbeProBot wins the third time in a row! They brigns again very detailed documentation. This time they surprise us with the creative use of the second ultrasonic sensor. Check their solution, both for documentation and video too.

The team of 3 boys from Deutsche Schule in Bratislava (DSB) - German international private school - show us the well documented solution and clever algorithm for measuring the distances. Congratulation!

Here we have some notes for all teams:
Very few teams thought to measure the room dimensions manually to have reference values (or at least one reference dimension, like 1 meter).
Regarding the equipment: although the ultrasonic sensor has a range of only 3 meters, if you had turned the robot around and added two readings together, you could have reached a range of 6 meters. This would have been enough for most rooms without the robot having to travel across the entire class.
And we have to repeat again: Sometimes it can be necessary to bring someone onto the team who will be solely responsible for documentation — taking photos, filming, and taking notes. Creating documentation is a very important part of engineering and design work.
