Challenge Rules
The Closed Loop challenge rules are exactly the same as the Open Loop challenge except for one import change to Rule #4:
The robot must start touching the West wall.
The robot that gets closest to the East wall - without touching - is the winner. A robot that stops while touching the East wall will be penalized 5".
Each team will get three runs. The team with the smallest sum distance, after the worst score is discarded, will be declared the winner.
You can use any robot design and ANY external sensors (e.g. ultrasonic or light).
