SPOKANE, Wash. – Three Shadle Park High School sophomores have refined their design of a prosthetic arm, earning them a return trip to the Washington State Math Engineering Science Achievement (MESA) competition in Seattle on Saturday.
Last year, the students admitted their prosthetic arm was heavy and a bit clunky and challenging to control. This year, Kleopatra Deltchev, Jessica Lim and Hailey Guyette started from scratch. They interviewed local professionals and changed their design completely. The end result: a lighter, more efficient model.
The students said their experience at the national MESA competition helped motivate them to do better.
“We got there and we’re like, ‘Oh wow, look at these arms,’” Deltchev said. “So we wanted to have an arm that’s more durable and also that would be more efficient for the tasks that we’re doing.”
The three students put in dozens of hours of time outside of school perfecting their prosthetic arm. They will compete against other regional winners at the state competition Saturday in Seattle. They hope to advance to the national competition in Portland, June 19-22.
