Toss Boss

Human-Powered Frisbee Launcher

Northeastern Senior Capstone Project

Toss Boss Presentation Photo.jpg
For my Senior Capstone, my buddies and I designed a human-powered frisbee launcher to help players safely practice catching and timing drills -- with an emphasis on cost-effective design, mechanical reliability, and user-controlled operation for consistent flight patterns.

Toss Boss in action: propels frisbees at controlled speeds and angles to simulate real flight conditions for training purposes. 

Key Successes

To confirm the launcher met the 35 rad/s threshold for stable flight, we tested it against hand throws and measured throw distance based on spring extension

We tested frisbee launches at varying spring displacements, averaging results from three trials per setting. The launcher reached a max distance of 70 ft. Data showed a linear relationship between spring extension and distance, consistent with Hooke’s Law. Accelerometer data was also recorded during tests
