The goal of this project is to test the compressor of a ventilator, that is used in the medical field, and to experimentally gather data and determine the best possible design by comparing different criteria. There are two design iterations that will be finalized for 3D printed and experimental testing. Once completed students will begin to build a test bench for running tests to find the compressor maps for the compressors which will show the projected map contours. Compressor maps will show RPM-Pressure-flow rate, Efficiency-Pressure-flow rate, Power-Pressure-flow rate, and Noise-Pressure-flow rate. Interfacing with sensored brushless DC motor, flow sensor, and pressure sensors will be done on Labview. Different compressors will be compared and the most efficient design configuration will be selected.

In this project, we are working for Laguna Tools to redesign the upper and lower bandsaw blade guides on the 14-Twelve bandsaw. Bandsaw's blades are supported by the guides in three directions: the two sides and the back side. The current design features a rail system where the guides are able to slide and be locked in place with a screw. Currently the lower guide's adjustment knobs are obstructed by the bandsaw table and other components making it difficult to properly adjust the guide. The objective of this project is to design the guides such that they are user friendly, have precise and accurate adjustments, and be easy to manufacture.

UCI Bike Frame is a senior engineering project devoted to the design and manufacturing of bicycle frames. In the past, the project has functioned as a UROP grant-funded club and later a mechanical engineering senior project "UCI Bike Builders" (MAE 189).  The senior project is focused on developing an additively manufactured weldless bike that will utilize multiple materials. This bike is experimental in nature and allows for greater customization while also reducing assembly time. The bike will utilize off-the-shelf carbon tubes which will be connected using custom additively manufactured titanium lugs. The carbon tubes will be fixed to the lugs using a two-part epoxy and fishing wire will be wrapped around the ends of each tube to ensure concentricity at the mating surface. Tolerancing will be extremely important in determining the strength of the joint. The 3D-printed lugs will have to be post-processed in the machine shop to ensure accurate tolerancing.

Background:

The UAV Forge team has a competition and requires a means of measuring drone thrust in relation to battery drain under various load conditions and varying configurations, such as quad-, hexa-, and octocopers. Previous attempts by the Forge team to measure drone thrust had been proven inefficient and unreliable. The Forge team requested a dedicated team to design and manufacture a safe and reliable means of measuring and recording drone thrust. This stand is unique as it measures the thrust of the drone as a whole assembly whereas other methods measure the thrust using only a single propeller and motor.

Background:

UAV forge needs a new tailsitter drone design that is capable of completing a range of tasks required in Association for the Unmanned Vehicle Systems International Student Unmanned Aerial Systems Competition. The drone will need to take-off and land vertically (VTOL) and transition between hover and horizontal flight like a traditional fixed wing aircraft.

With wifi being so prevelent it is easy to forget that it is not as commonplace as we think. In search and rescue scenarios many first responders often get trapped or injured while on duty with virtually no way to locate them. There are countless factors to take into account that make it impossible to prepare for with traditional tracking software. However, by using a passive RFID tag we can circumvent all the hassles and worries of a lost signal or power source to focus on retrieving lost or injured personnel. 

UAV Forge is a multidisciplinary engineering design team that focuses on the design, manufacturing, programming and testing of autonomous aerial vehicles. The design aims to fulfill the constraints that allows the team to participate in the AUVSI SUAS 2021-2022 competition season. The AUVSI competition requires that the system’s UAV have autonomous flight capabilities, ability to perform object avoidance of stationary and dynamic objects, the ability to do object detection, localization, and classification. The system must also perform an airdrop task wherein UAV Forge will be manufacturing an assembly that will interface the UAV with a descent and autonomous ground vehicle. The ground vehicle,once landed, will autonomously drive to its’ set destination to complete payload delivery. Though the emphasis for this year’s team is to perform well in the competition setting, the primary objective is to ensure the undergraduate students participating in the project apply their engineering skills to a compelling real-world problem.

We are UC Irvine’s Electric Racing Team, a senior design project in the Henry Samueli School of Engineering. Founded in 2011, our mission is to help students grow as engineering professionals by creating a space where they can apply their engineering knowledge to a hands-on project. In addition to strengthening the students’ skills, this venture helps foster team-building, communication, and leadership expertise. The final goal for this project, along with allowing the students to build an electric race car from scratch, is to compete in the student FSAE competition.

Background

Client-focused project to develop prosthetic opposable thumb that allows for grasping objects with that hand. Work with an individual who retains portions of fingers on right hand, and has left arm and both feet amputated.

Project Team will interview client to assess and analyze needs, and obtain a 3D scan of residual hand. Team will then brainstorm design concepts before creating a CAD model of the prosthetic thumb prototype. Team members will perform calculations to determine degrees of freedom and force requirements. Appropriate adjustments will be made to the CAD design before first prosthetic thumb prototype is 3D printed. After testing the prototype with client to perfect the prototype, over several iterations, the design will be finalized and fabricated.

Our project was focused on exploring the resources available in the public knowledge space for creating advanced robotics. We specifically focused on the open source technology and guidance that would allow a small team or individual to create a versatile, efficient, and low cost robot that could be customized to act intelligently and effectively in as many different situations and environments as possible.

The result of the past 9 months of work is a robot dog in the sub $250 range that is both cute, powerful, and intelligent in how it receives and carries out commands. Given more time, we know our robot could acheive even more and we are excited to see how far it goes in the future.

This project was to make a robotic quadruped in the form of a dog.  It should be able to be voice-controlled using recognized commands to move via servo-controlled leg joints as well as perform speech output.  To achieve this, we utilized 3-D printed material for the chassis and legs as well as bearings for structural support.  These parts hold a “Raspberry Pi 4” connected to a servo hat that leads to 12 different servos, three for each leg.  As far as software, we imported a voice recognition library, taking advantage of Google’s voice recognition taking input from a USB microphone and outputting from a speaker.

Background:

Drones (often referred to as unmanned aerial vehicle (UAV)) are unpiloted aircraft or spacecraft that can be autonomously or remotely controlled. They are used for a wide variety of applications such as the military, space exploration, and for commercial use, which allow ordinary people and companies to fly these vehicles for all sorts of purposes. Drones usually run on lithium polymer batteries (lipo Batteries) but hydrogen fuel cells can also be incorporated.

Ford Automotive Company partnered up with UCI students to redesign the current HVAC duct in a Lincoln Navigator. As of today, the manufacturing process of the duct utilizes injection molding where a large initial investment is needed. To make up for the high initial cost, large volume production is required in order to lower the unit cost. However, to lower costs for low volume production (<20,000 units), UCI students will redesign the duct for Additive Manufacturing. The engineering design process will be implemented to create at least 3 designs that maximize nesting efficiency of a Multi-Jet Fusion 3D printer, with the overall goal of lowering the unit cost and minimizing performance loss compared to the current injection molded design. Students will present these proposed designs with an associated business case benchmarking against conventional manufacturing and identifying production volume opportunities.

Whoopy Wipes is a sanitization device capable of dispensing warm, moist towelettes at the touch of a button.

Background:

Due to the recent COVID-19 pandemic, a higher standard of sanitation is required to safely navigate the world. This problem is particularly concerning because it affects almost every aspect of our lives. As indicated by the CDC, COVID can last on surfaces from hours to days. In order to satisfy the increased demand for a sanitary environment, we aim to design an autonomous sanitation device capable of sanitizing an entire surface to limit the risk of transmission.

Goal:

Thermal management systems, involving the use of technology to control and maintain temperature within a certain range, have applications across many industries. With the continuing advancements in electronics and other high power density producing systems such as spacecraft, the power they generate is expected to increase. These systems are projected to exceed a power generation of 1400 W/cm2. The absence of efficient cooling systems and power dissipation, however, will lead to the degradation of the system and short term use of components.
