Week 6: Overview

The group tested the SeaPerch at the pool in the Drexel Athletic Center. It was found that on average the original SeaPerch moves at ...... This was determined by measuring the length of the pool (in meters) and dividing it by the average time it took the SeaPerch to cross the pool. The group plans to use this information to test the final design of the Perch to confirm whether or not the new design is more hydrodynamic. While testing the original design, it was found that the right motor was weaker than the left motor, causing the SeaPerch to turn slightly while moving. This slowed the SeaPerch down while testing since both motors were not running at the same time. Also, the cord connected to the battery was not long enough to cross the entire pool, so the person controlling the SeaPerch had to pick up the battery and walk the side of the pool. The tugging of the cord also contributed in slowing down the SeaPerch. The group then started to plan and design the new construction of the SeaPerch, and chose what modifications were to be made. These changes are displayed and described in the New Design post on the blog. The construction of the new design will begin in class this week, and will be finished by class in week eight. That will allow time for testing and alterations in week nine to finalize the final design and determine if the SeaPerch, is in fact more hydrodynamic.
