Team member Jake Van Buren said he enjoyed the entire experience, but he had an especially fun time at the party at the end of the trip.
It featured a D.J., magician and face painter, Escobar said.
Each student took something different from the experience.
Edmund Doyle said he had fun watching the judging session and looking at, and learning about, other models.
"I really learned that engineers can help the world," added Zubin Mukerjee, who also represented the school in Washington.
It wasn't all fun and games, though, the team said.
"The project in general was really frustrating and fun at the same time," David Lasselle said. He said making sure everything is working properly and looks good can be stressful, but it is worth it in the end.
"There never seems to be enough time," Escobar added.
