T-Shirt Cannon


During the 2020/2021 school year both FTC and FRC were forced to go remote due to COVID. Our FRC team did not compete in the at home challenges for the season but instead a small group of students decided to build a t-shirt cannon that we can use at football games, basketball games and any other events where we can launch t-shirts and promote our robotics program. as well as our sponsors. 

The robot made its first debut at the Van Wert High School 2021 Good Will Games in front of the entire High School. It then made its first public appearance at one of the 2021 home football games. 

Detailed information about the robot can be found below as well as the cannon's technical specifications.
