Mini Culmination Prep- Day 5

On Tuesday, Gillian and I played around with our rover the whole time. It would not go and comeback to the same place. We changed the battery, the motors, everything and we played with our program, but the rover was still being inconsistent. On tuesday in homework center, though, Bert and I problem solved. He suggested a tunnel and I decided it would be more logical to make a track/road thing. I used 5 rulers on each side and I taped them to the floor. this way, the rover can't go side to side, and it must come straight back to where it was before. It made me very happy!!
