sea perch testing

Working with Charles County Parks and Recreation, we were able to schedule testing time at Lackey High School pool.  First objective:  establish proper buoyancy for the Sea Perch vehicles.  Some teams added weight.  Some cut off foam.  Next objective: get the Sea Perches to steer in a straight line and up and down.  Motors were repositioned.  Some teams discovered wiring problems.  Third objective: travel through a simple obstacle course made from hula hoops fastened to the lane lines.  Abby's team was the first (and only?) to successfully make it through the course.  A subsequent "Sea Perch Tweaking Day" is planned for Nov 8.  Next pool testing day is Nov 22.
