Adjustable Head Tube Angle Headset

The purpose of this project was to design, build and test a headset capable of changing the effective headtube angle of a mountain bike by +/- 2 degrees from the original headtube angle of the bike. The design had to be alterable on a ride with no tools needed.

Activities for Mech E’s

New lab activities for ME 329 – Mechanical Systems Design designed to embody Cal – Poly’s Learn by Doing motto.

Composite LiftWalker for Shurouq

          The picture above shows our final prototype, successfully lifting our team member Daniel Martinez.

The goal of this senior project was to design and build a new version of our project sponsor Charlie Gutierrez’s LiftWalker for Shurouq, our client.

Shurouq is a young woman who lives with her family in Egypt. She was born with multiple health conditions which resulted in leg contractures that have since left her unable to walk.

Charlie’s device, the New LiftWalker, has helped dozens of people with disabilities similar to Shurouq’s. However, Charlie’s standard design is made of stainless steel weighing up to 80 lb, which is both difficult and expensive to send to Egypt. For this reason, Charlie turned to the Mechanical Engineering Department at Cal Poly, challenging us to redesign his LiftWalker out of lightweight composite materials.

Doggone It

Peter is a retired military veteran who had his right leg amputated above the knee. He uses a wheelchair to get around and needs a way to get his service dog in and out of his truck safely and easily. Our product will assist with prolonging the dog’s life and mobility.

Electromagnetic Actuator for Camless Engines

The purpose of this project was to design, build, program, and test an electromagnetic actuator that could be implemented on modern-day automobile engines. This project acts as a year-long senior project for four Mechanical Engineering majors at California Polytechnic State University, San Luis Obispo (Cal Poly SLO)
