Academic Magnet High School’s (AMHS) Robotics Team won first place in the Open Class Engineering Process and Design category in the 2019 SeaPerch Challenge held at the University of Maryland on June 1-2.
Team members included Gage Gailbreath, Stephen Hilton, Daniel Killough, Angela Li, John Paradise and Bohan Wang.
"As teachers, we have standards, curricula and proven programs that we follow, but it is these kinds of real-world projects that evolve students into scholars,” said physics teacher and AMHS robotics team sponsor/coach, Maria Desbrow. “My kids are seriously smart.” Organized by RoboNation, the international SeaPerch competition presents an opportunity for high school students to learn about STEM-related fields by creating an underwater remotely operated vehicle (ROV).
The competition challenged students to have an ROV that executes rescue operations. Using SeaPerch kits, a Nanoline controller, Arduino boards and sensors, AMHS Robotics Team members created an autonomous system of underwater rovers complete with infrared sensors and GPS technology. The system allows the small vehicles to detect and avoid debris, while simultaneously identifying and pinpointing possible rescue persons and locations within bodies of water.
The team built two rovers: a smaller scouting bot, which was half the size of a normal SeaPerch kit that was outfitted with sensors to record information; and a Search and Rescue bot, the normal size for a SeaPerch kit, that has a malleable hook to pick up and move objects within the rescue and recovery course.
Over 2,000 middle and high school teams competed over the past year throughout the United States. Two hundred of these groups advanced to face international teams from four countries to compete in three categories of speed and agility, rescue and recovery, and engineering process and design. AMHS competed in the regional competition held in Charleston against 30 teams in March of this year, then advanced to the international challenge.
Although the AMHS robot performed respectably in the obstacle and mission courses, the judges were most impressed with the engineering process and design the students created. While the team’s automation system appears to be very sophisticated technologically, the rover itself was physically built using recycled pool noodles, a coat hanger, and a pencil on top of the basic SeaPerch kit. The rover looked so simple that, during the question and answer portion of the presentation, judges remarked, "On one side, we have NASA, and on the other is what you can find on the floor."
As the typical SeaPerch robot is made using no more than $25 beyond the original SeaPerch kit, the team decided to follow that general low-budget model, with added technology.
“We found that the more complex we made the rover from stock in terms of our design, the more problems we had with it. We decided to devote more time to making the automation run more efficiently than making the rovers look nice," Killough commented.
“Simpler is better and that was proven through this competition,” added Stephen Hilton.
The students not only learned about the process and challenges of creating an ROV but how their work can go in solving real-world issues.
“The 2019 SeaPerch Challenge mission was inspired by the real-life events of the 2018 cave rescues in Thailand,” said AMHS principal Catherine Spencer. “AMHS students know firsthand the threats and dangers of rising waters and worked together to create a rover capable of navigating not just a cave, but possibly a Lowcountry waterway or flooded street to assist with search and rescue efforts. We are proud of their achievement as well as their desire to create a device to improve their community and world.”
