Mechanical Hopper

Fall 2024, First Year Engineering Project

Rapid Prototyping Mechanical Design Spring Systems

In the first year "hopper project" at Olin College of Engineering, students build a jumping contraption inspired by nature and refined it through rapid prototyping. I took inspiration from the Springtrail hopper by creating a tail that is tensioned with an elastic rubber and released with a balloon-timed trigger.

The final prototype met many of my design goals. I enjoy the balloon trigger.

To achieve my final prototype, I went through multiple designs and iterations. Starting with simple concept sketches for various hopper designs, I moved on to building simple 3D sketch models to validate design choices (such as the trigger mechanism concept). While my first full prototype was already capable of a self-triggered jump, additional iterations targeted improved airtime.
