Cal Poly Fluid Power Vehicle Challenge 2024, J. Mason Gray, Ryan D'Amour, Alberto Acho Lopez, Christian Ferrandino, Johnathan Dietz
Mechanical Engineering
In this Final Design Review, the Cal Poly Fluid Power Vehicle Team competed in Norgren’s 2024 Fluid Power Vehicle Challenge. The design need of the competition was for college teams to compete with human-powered, hydraulic-driven vehicles in an endurance race, a sprint race, an efficiency race, and a regenerative power race. The competition need was to design a vehicle to win in as many races as possible, achieving the highest overall score and winning the competition. With a design emphasis on the endurance and sprint race, the Cal Poly team designed a fluid power system that fastened to a purchased …

This document presents the engineering design process used to develop, manufacture, and test a new and improved iteration of a hitch cart prototype. This process was performed by a team of four mechanical engineering seniors as part of California Polytechnic State University, San Luis Obispo’s senior design pathway. The goal of this project was to develop a sturdy and reliable iteration of our sponsor’s hitch cart prototype, that integrated the functionality of a vehicle hitch cargo platform and that of a height adjustable cargo cart into a single streamlined and easy to use product. This design could be used by …

Mechanical Engineering
The goal of our project is to convert an electric go cart into an autonomous testing platform. We must enable autonomous braking, steering, and acceleration with electro-mechanical systems. We began the project with ideation to create our initial design and have since received ample feedback from faculty, students, and our sponsor. With this feedback we were able to refine our preliminary ideas and produce a detailed design supported with ample analysis, research, and external advice. We have developed our project in four main subsystems: Steering, braking, acceleration, and emergency braking. Following, we procured, manufactured, and assembled all of our designed …

In this report, the Featherweight Cycles design team puts forth the scope and overview of their design project, discusses background research and competitor analysis, and presents the project’s final design and manufacturing plans. The overall goal of this project is to fabricate and compete in the Fluid Power Vehicle Challenge, hosted by the National Fluid Power Association. To better define the design process, the team researched previous year’s designs from Cal Poly, as well as winning designs from the last two years to form a baseline of knowledge about competing schools’ designs. After researching multiple design paths, Featherweight Cycles chose …

The goal of this document is to clearly define the problem parameters and project objectives and to clearly describe the design process, planned final design, and manufacturing and testing procedures for the senior design project of Team 26: SAVER -- the Surface Autonomous Vehicle for Emergency Rescue. This is both for the purpose of project planning and for clear communication between all parties involved in the project.
The objective of the SAVER project is to develop a proof of concept for an autonomous maritime search and rescue vehicle for aiding in man-overboard missions. To accomplish this goal, a list of …
Final Design Report For Human Powered Vehicle Drivetrain Project, Derek Fromm, Luke Opitz, Michael Juri, Olivier Côté
Final Design Report For Human Powered Vehicle Drivetrain Project, Derek Fromm, Luke Opitz, Michael Juri, Olivier Côté
Mechanical Engineering
The Cal Poly Human Powered Vehicle Club is building a bike to surpass 61.3 mph in 2019. The club and their mentor, George Leone, have proposed a senior project to design, build, and test the drivetrain for this year’s human powered vehicle. Research into human powered vehicles and their drivetrains has shown that the power that a rider can output and the efficiency at which the rider can pedal depend extensively on the design of the drivetrain. Despite the existence of standard bicycle drivetrain designs, the senior project team has found that the best design to meet the club’s requirements …

The Cal Poly Mechanical Control Systems Laboratory currently employs an outdated device, known as the Motomatic, to teach students about various motor characteristics and control methods. These include open-loop vs. closed-loop control, speed vs. position control, and DC motor response curves. The current device does not function properly and produces unreliable data due to overwhelming non-linear effects such as stiction and shaft misalignment. Our team was tasked with designing a replacement device that retains many of the same educational goals as the original lab procedure, while also adding new educational goals pertaining to the device system dynamics. The new apparatus, …

Autonomous Collision Avoidance, Thomas Stevens, Elliot Carlson, Ian Painter
Mechanical Engineering
A steering controlled, autonomous collision avoidance system has been developed by California Polytechnic State University. This system represents a step in the direction of fully autonomous driving, while allowing the driver to maintain control of the vehicle during normal driving conditions. In the case of an imminent collision, the system removes control of the vehicle from the user and autonomously steers around the obstacles. The final system is able to avoid two static obstacles with a 95% pass rate and one moving obstacle with a 50% pass rate. With full scale, fleet wide, implementation of this system it is expected …
