Building Progress 4

     This week we thought about the ways to make our seaperch more fishlike which help the control of the seaperch. However, it was difficult to find a place where we can make tests. Thus, we are going to have a negoation with managers in the swimming pool of Drexel. If it doesn't work, we are going to buy a big litter bin, since we want to focus on the balance of our seaperch. When we did the first test in a bathtub, we found a problem that the front of the seaperch was to light that it would float on the water. So we want to bind something heavy to the front of the seaperch. However, the bathtub was not deep enough. We could not do a lot tests on it. It was the task on this weeks lab. We want our seaperch can balance in the middle of the water, so we can make the seaperch up down easily which is important to be a good sensor to test the height.
