Built With Heart: Mustang Engineers Serve the Texas Special Olympics

Lutheran High School's engineering students are transforming the way athletes with special needs experience sport — one circuit board at a time.

There is a certain kind of work that changes you — not because it is difficult, but because of who it is for. For the engineering students in Mr. Schuetze's class at Lutheran High School San Antonio, that work comes every year in the form of a humble but extraordinary mission: building and improving machines that help athletes with special needs participate in sports they love.

This year, as the Texas Special Olympics Summer Games prepare to take place in Melissa, Texas, the Mustang engineering team is loading their creations for transport — devices that have been designed, assembled, tested, and refined right here in our own school's classrooms.

"This, along with FIRST Access, is some of the most rewarding experiences in my robotics career. I've had many, but these nearly every time bring a tear to my eye and love fills my heart to see our students want to do and make these things in service to others." — Mr. Schuetze, Engineering and Robotics Instructor.

The original "Mustang Free Throw Machine" is still at the center of this year's effort, and is in it's third iteration.  It is an Arduino-powered device that enables athletes to experience the joy of shooting a basketball, regardless of physical limitations. What began as a prototype held together with a breadboard and a tangle of colorful jumper wires has been completely rearchitected by students this year into a far more robust and reliable system. All five motor controller wires now mount cleanly in channels 0–4 on a custom Arduino shield, while user buttons and limit switches are soldered directly to the board — dramatically reducing the chance of a loose connection during an event. Students also disassembled, inspected, and reassembled the gearboxes on the upper motors, and are now dialing in motor speeds in the updated code to optimize performance.

The engineering logic is simple and purposeful: every loose wire is a potential failure point in the field. When an athlete is waiting, hopeful, and ready to play, reliability is everything.
But the Free Throw Machine is only part of the story. The class is also converting a Homerun / Tennis machine from its original VEX system to an Arduino and non-VEX motor — a meaningful rework requiring new hardware and entirely new code. A fishing carnival game is also in development, built from the ground up as a new addition to the lineup. And students have designed a stomp rocket device — a direct request from SOTX volunteers at last year's event — which required real investment in pneumatic components and represents exactly the kind of student-led, needs-driven engineering this program is known for in our pursuit of excellence.

What makes this program genuinely remarkable is not just the technical skill on display — it is the orientation of that skill toward others. These are not passion projects built for a grade or a trophy. They are tools built for specific human beings: athletes who deserve to experience sport in all its joy, and who will be waiting at the Summer Games in Melissa this week.

The Texas Special Olympics organization has taken note, and conversations are underway about how best to formally recognize Lutheran High School's service to the program.
In the meantime, the machines are loaded and ready. The code is being dialed in. And a group of Mustang students will soon stand at the edge of a gymnasium in Melissa, Texas, watching an athlete sink a free throw — made possible by work that started right here in San Antonio.

Go Mustangs. In service to others, to the glory of God.
