My group and I were having a lot trouble at the start with this challenge, our code was not behaving at all. Then Will came over and helped us with the code and it finally started working. The the aim of this technic is when the sensor picks up colour it stops. I really enjoyed this challenge and I had a lot of fun. Here is a video of our robot working.
This challenge was impossible because we had to trim the paper so there was enough room and it did not touch the paper. It also had to got round in a square shape which really hard to get the angles right. But once we were finished we were so relived. I can’t wait to see what other challenges are install for us throughout the year!
