Cal Poly Battle Bot (F41), Jyotaaver S. Nirula, Andrew D. Peterson, Johnathan W. Waldmire, Nathaniel Ab Davis

Mechanical Engineering

This senior project endeavored to design, construct, and optimize a 120lb robot combatant tailored for the competitive arena of combat robotics. The project is a collaborative effort between mechanical, computer, and electrical engineering students at Cal Poly, combining diverse expertise to achieve a unified goal. Our competition, RoboGames, was in April of this year in Northern California.

The mechanical engineering team assumed primary responsibility for the physical components of the battle bot, focusing on three pivotal components: a robust drivetrain, armor, and a highperformance vertical spinner. These elements constitute the foundation of the battle bot's offensive and defensive capabilities, crucial …

Garbage Float, Gabor Papp, Max Woolverton, Scott Ulatowski, Daniel Ross, Nicholas Gayle, Bryan Merchan-Aragon, Noah Yco, Nicholas Fawcett, Jared Wright, Abdulaziz Salman G Alshahrani, Andrew Mcquire

Mechanical and Civil Engineering Student Publications

Trash pileup in our waters is an increasing problem. Removing floating plastics and debris from our ecosystem would reduce mortality rate of marine animals. Solutions for this already exist but most of them are proprietary and expensive. Therefore, an autonomous, publicly available and cheap alternative was developed to skim and clean the water surface from garbage.

8 Dof Quadrupedal Hopping Robot, Clayton T. Elwell, John Bennett, Tyler Mccue, Daniel Munic

Mechanical Engineering

The goal of our senior project was to fabricate an eight degree of freedom (DOF) prototypical quadrupedal robot, develop a controller than commands the quadruped to repeatedly jump 10 cm in the air, and fabricate a modular test stand to safely deploy our controller on the quadruped. The creation of a functional quadruped will bring attention to Dr. Siyuan Xing and Charlie Refvem’s research group, Cal Poly Legged Robots, and will give future Cal Poly undergraduate and graduate students a learning tool to explore dynamic control of biomimetic robotic systems.

Over the course of our senior project, we successfully manufactured …

Autonomous Navigator Mobile Robot Upgrade, David Sansoucy

Thinking Matters Symposium

The mobile robot platform has been developed over the course of 10 years at USM. In Spring 2020, Belle-Isle and Werner updated the previous framework by rewriting the software to use the ROS framework running on an on-board Raspberry Pi 3. They also implemented navigation using an A* motion planning algorithm and image processing. In Summer 2021, Ames incorporated Lidar and Kinect sensors onto the robot to improve its real-time navigation capabilities. He also made improvements to the power distribution systems. This project aimed to build on the ROS frameworks developed by the previous 2 teams with the main goal …

Chemical Clean Automated Loader, Jordyn Bryner

Williams Honors College, Honors Research Projects

TTM Technologies (TTM) is a global printed circuit board (PCB) manufacturer. The work described in this report was completed in the TTM North Jackson, Ohio location. This plant focuses primarily on the manufacturing of rigid and rigid-flex PCBs for the aerospace and defense industry. TTM North Jackson has an ongoing labor dependency issue due to the shortage of workers the nation is facing. To solve this problem, TTM has focused the efforts of their new engineers and interns on automating processes that are labor dependent. The goal is to provide design guidance to be used later by TTM to automate …

Implementation Of An Autonomous Guided Vehicle (Agv), Allen St. Myers, Alan Miller

Williams Honors College, Honors Research Projects

This report thoroughly represents a proposal to AAM Metal Forming Minerva for the implementation of an AGV (Autonomous Guided Vehicle) Unit. Our recommendations are made with consideration to existing manufacturing processes and demonstrate how using an AGV would be a net positive investment for the company. By first examining the current operating costs, a three-tiered proposal is tailored based on increasing investment cost. Each tier increase encompasses the previous tiers’ proposed improvements while also growing in complexity and investment cost. The results of our research indicate that our Tier 2 proposal will provide the most benefit to our facility now …

Surface Autonomous Vehicle For Emergency Rescue, Max Emerick, Ryan Shields, Christopher Feickert, Raymond Impara

Mechanical Engineering

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 …

Answering Food Insecurity: Serving The Community With Food And Knowledge Using Technology, Courtney Simpson

Purdue Journal of Service-Learning and International Engagement

The courses of Tech120, CGT110, and ENGT 180/181 and Red Gold at Purdue collaborated to design a robot that would plant and water a garden for a local community charter school. The students centered the project on the users’ needs for fresh food, nutrition education, and early exposure to STEM for children. The school, Anderson Preparatory Academy (APA), is comprised of many children who come from low-income families and are in the free or reduced lunch program. Inspired from “Farm Bot,” a similar system that allows for almost hands-free gardening, the “Boiler Bot” is designed to be scalable so children …

Design, Testing And Evaluation Of Robotic Mechanisms And Systems For Environmental Monitoring And Interaction, James K. Higgins

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Unmanned Aerial Vehicles (UAVs) have significantly lowered the cost of remote aerial data collection. The next generation of UAVs, however, will transform the way that scientists and practitioners interact with the environment. In this thesis, we address the challenges of flying low over water to collect water samples and temperature data. We also develop a system that allows UAVs to ignite prescribed fires. Specifically, this thesis contributes a new peristaltic pump designed for use on a UAV for collecting water samples from up to 3m depth and capable of pumping over 6m above the water. Next, temperature sensors and their …

Design And Testing Of A Novel Adhesion And Locomotion Method For Wall Climbing Vehicles, Jim R. Stefani

Master's Theses

The objective of this project was to design, construct and test a wall climbing vehicle which uses a novel vacuum tread system for both adhesion and locomotion. The design and manufacturing of this proof of concept vehicle is detailed with particular emphasis on the design decisions that proved most impactful to the performance of both the vehicle and the tread system. Adhesion performance was characterized by a series of tests that validate the concept, but also identify improvements and design recommendations for future embodiments of the adhesion/locomotion system.

Artificial Skin Tactile Sensor For Prosthetic And Robotic Applications, Ross James Miller

Master's Theses

To solve the problem of limited tactile sensing in humanoid robotics as well as provide for future planned mechanical prostheses, an innovative tactile sensor system was created and embedded into two realistic-looking artificial skin gloves. These artificial skin tactile sensors used small piezoelectric ceramic disks to measure applied force at multiple points on each glove. The gloves were created using silicone rubber to simulate both the texture and look of human skin, while maintaining both flexibility and durability. The sensor outputs were buffered by high-impedance voltage-following operational amplifiers, and then read sequentially using a multiplexing scheme by a microcontroller. Sensor …
