South El Monte SeaPerch Underwater Robotics Team Makes it to Nationals

SEMHS SeaPerch

After completing a series of challenges to win first place in the high school division of the 2019 Los Angeles Regional SeaPerch competition in March, the South El Monte High School Scuba Squad will showcase its underwater robotics skills at a national competition June 1-2 at the University of Maryland.

This is South El Monte High School’s second appearance at the nationals since 2015. This year’s aquatic engineering team, advised by science teacher Michael LeGaspe, is made up of seniors Josselyn Melendez, Jose Robles and Erik Zepeda.SeaPerch

“We will have to work extremely hard to win in the nationals,” Zepeda said. “We meet every Friday afternoon to test our craft. There is a lot of trial and error in the process, but we are up to the challenge.” 

The SeaPerch Challenge is an underwater robotics competition designed by the U.S. Navy to inspire students to learn science, engineering, technology and math (STEM) subjects. Schools from 31 states, as well as Puerto Rico and New Zealand, will be competing in the nationals.

For the regional competition, the team applied ideas from Project Lead The Way (PLTW) curriculum to navigate a Remote Operated Vehicle (ROV) through a rescue and recovery mission and obstacle courses, taking first and second place, respectively, and being awarded first place for its engineering notebook.

“The competition was very challenging, because it was pouring rain throughout the day and we had trouble seeing our ROV in the water,” Melendez said. “I discovered that some of the target beacons we were tasked with lighting were an inch taller than we had expected, so we had to make adjustments. Our PLTW training helped us out immensely.”

Scuba Squad members are working to improve the ROV ahead of the nationals, trying to balance buoyancy, control and speed, as well as adjusting the ROV’s capability to retrieve objects as they emulate a search mission modeled on the rescue of Thai students from in a cave in 2018.
