To test if the water was polluted or not polluted, we intended to use a paper towel and a color sensor. We would be able to detect whether there was pollution or not based on whether the color sensor detected that the paper towel was green or white. To collect water, we intended to use a sponge and a pully system that would deploy once the OTV got close enough to the water. The paper towel would get wet being able to collect the water. For traversing the course, we obtained big wheels intended to deal with the set of rumbles as well as the log to limit the amount of code needed to avoid obstacles as well as so that we would not have to go under the limbo and worry about a height limit.
