Animatronics
Through the Butler Tech program in Butler County, Ohio, my team and I were given the remarkable opportunity to attend the Technology Student Association’s National Competition in 2023 for Animatronics. As one of Ohio’s teams among hundreds of high schools from all over the country, we proudly showcased our hard work and dedication on a national platform, gaining invaluable experience.
My Role
My role in this project was the team leader, overseeing the placement of all the intricate electrical components and pneumatics. Additionally, I undertook the challenging task of programming the PLC and Arduinos, while also leading the construction of the classic roller coaster. Furthermore, I contributed by modeling parts with CAD and executing the 3D printing of these precise and essential parts.
What did it do?
The Technology Student Association's Animatronics prompt tasked us with creating an enclosed exhibit that would operate fully autonomously and be showcased at a state welcome center. Our exhibit showcased the state of Ohio and comprised a functioning roller coaster, a realistic rocket ship, a football stadium, and an illuminated Rock & Roll Hall of Fame, with a dazzling light-up guitar.
PLC and Electronics
The project's controllers included an automation direct PLC, electronic valves, and sensors (pictured), along with an Adafruit music maker Arduino shield, and an additional Arduino responsible for powering the roller coaster’s lights and motors (not pictured). Using a comprehensive array of components such as fuses, power supplies, relays, terminal blocks, LED buttons, an LED light strip, spotlights, and other electronic elements, the entire system operated seamlessly and autonomously. The pneumatic cylinders were managed by electronic valves, while the air compressor automatically refilled, allowing the football field and rocket to move independently each time the button was pressed.
Lighting
The fully automatic lighting system used four dynamic spotlights, a vibrant multi-colored LED strip, and illuminated buttons. The synchronized operation meant that specific buttons triggered the activation and deactivation of corresponding spotlights, while the LED strip cycled through a spectrum of colors, based on each action. Powered by an Arduino, the chasing lights of the roller coaster provided a timeless aesthetic, reminiscent of classic amusement park attractions.
Awards
In 2023, our team entered the Technology Student Association National Conference and won the 2nd place award out of all the other projects and groups nationwide.
