Design and integrate a modular telescope subsystem combining COTS optics with custom fabricated subsystems for automated tracking, imaging, power management, data processing, and wireless telemetry to enable fully autonomous celestial observation and analysis. The student team will be responsible to develop as much of the needed capability organically and only rely on COTS to a minimal extent.

ASTRA (Autonomous Sky Tracking & Reconnaissance Apparatus) is intended to be a fully integrated optical telescope designed for precise, hands-free observation of celestial targets. The design centers on a COTS telescope as the primary optical element. All other subsystems, including pan-tilt actuation, power delivery, imaging integration, and wireless telemetry, are expected to be developed from individual components or custom, student fabricated modules. At its core, ASTRA is focused on high quality astrophotography and the ability to identify celestial objects, capture clear images of space, and utilize on board algorithms to analyze and post process images. The system shall include automated tracking, motorized optical zoom, dynamic focusing, active light filtering, and self-calibration using celestial reference points. Additionally, the ASTRA system shall support simultaneous viewing with naked-eye and camera-based viewing, allowing both direct visual observation and real time digital imaging. The system shall utilize a GUI in conjunction with visual data, collected from the on-board camera system, to enable seamless remote operation

Carnival games require incredible skills and precision. Most of the time they are scams, tricks, or money sinks. We are looking to have a system created to help us win every target-based carnival game we come across. This system needs to be able to be fully autonomous, we will be focused on distracting the attendant while the system operates. Low profile, I cannot pull up a car sized system to a carnival booth, it will need to be low profile enough to carry on my back before deployment. Highly efficient, I only want the best prizes, so the system should be able to target, recognize, and only shoot at the highest priority targets. Accurate, the system will need to be able to hit targets of varying sizes/colors and moving at varying speeds.

Project Description: The recent COVID pandemic revealed the importance of sterile, enclosed, and properly fitting face coverings for minimizing the spread of the pathogens and for protecting one’s health, particularly for health care workers routinely exposed to infectious pathogens. Furthermore, recent measles, mpox, and bird flu outbreaks have infectious disease experts concerned about our preparedness for the next pandemic. Frontline healthcare workers often use multiple face masks and shields every day to minimize potential exposure to pathogens. Frequent mask or shield changing risks pathogen exposure from contaminated external surfaces, while insufficient masks and shields also risks contamination, and overall, heavy consumption of this PPE (personal protective equipment) generates significant and potentially hazardous biomedical waste. Facemasks such as the N95 type don’t seal well and they cover most of the wearer’s face making it impossible to read lips or emotions. A reusable, well-fitting, self-sterilizing, enclosed face shield could protect the wearer, allow for mor effective communication, and would generate much less biomedical waste. Ultraviolet (UV)light has proven to be an effective disinfectant for decades and the UVC band (100 - 280nm) particularly has demonstrated the most effective antimicrobial properties. However, UVC light can damage the eyes and skin and even cause skin cancer. Surprisingly, a recently discovered narrow band within the UVC band (200 – 230nm), often referred to as far UVC (fUVC), does not harm skin or eyes yet still retains excellent disinfecting properties. The project goal is to create a process for making custom form-fitted face shields that can be used by itself or with a modular ventilation system and/or a modular UV disinfecting light source.
Scope:
(1) Identify a 3D facial scanning tool to produce accurate models of a person’s face.
(2) Identify and develop a method to shape the plastic shield material to conform precisely to the person’s face.
(3) Identify optimal light weight materials, shape, and volume of air to be enclosed by face shield for comfort, respiratory mechanics and ease of use
(4) Identify optimal HEPA filtration method to achieve disinfection while maintaining respiratory mechanics
(5) Integrate raw HEPA filter material to enable adequate passive ventilation without blocking the face.
(6) Integrate a commercial off-the-shelf COTS active (air pump-based) ventilation system incorporating HEPA air filtration.
(7) Stretch Goal: Integrate commercial fUVC light source to face shield to uniformly disinfect surfaces when activated. This can utilize the previous work completed on a capstone project last year that included: fUVC light source, drive electronics and exposure control.
(8) Build a prototype system and manufacturing method, complete with system diagrams, mechanical drawings, electrical diagrams, and manufacturing work instructions.
(9) Assess and incorporate appropriate bio-medical design elements to maintain optimal respiratory mechanics for the face shield user.
(10) Present results in a PowerPoint presentation.

Design, build, and bench test an optical metrology module that measures the size, velocity, and particle trajectory of microspheres between the size of 100-500 um.

Problem and Capstone Statement (using microspheres):

The detection and qualification of Sn debris after the creation of plasma is critical for informing the extent of contamination in the scanner. This information can be used to tune system design to minimize debris creation and ensure a high yield of wafers. It is desirable to produce a metrology system that measures the size, velocity, and trajectory of moving targets - microspheres - for quantifying the extent of Sn debris within the EUV system to inform Sn management strategies.

The project task is to design and build a prototype system using commercial off-the-shelf parts, supplemented by 3D-printed or locally-machined parts, to deliver a unit that will be tested on a UA test bench. The approximate size of the system (metrology unit) consisting of the microsphere launch system, light source, and detector should fit inside a cube of no more than 2ft on each side – additional circuitry for collecting and displaying outputs need not be included in the contained metrology unit. Further details will be explored by the team during conversations with ASML leads.

Project will conduct the system architecture, design and prototyping of a demonstration airframe and propulsion system for a small multi-role solid-fueled ramjet. Students will use engineering design principles coupled with analysis and supporting wind tunnel testing (as applicable). Trade studies around materials selection, manufacturing techniques, and system performance will be performed. Prototyping of key components will be performed using additive an conventional manufacturing techniques.

Project Goal/Summary: The purpose of the present project is to build a quantitative urinary flow and function system for both home and hospital use. UroSMART will offer two new and novel features compared to existing technologies: 1. A Urodynamics capability - measuring urinary flow, urinary volume and total output for a given time with a simple system paired with a cell phone app for patient readout as well as transmission to care workers; 2. Neo Cath - an improved design urinary catheter, utilized when drainage is internal, with features of reduced pain and anti-infective properties for enhanced biocompatibility, patient comfort and experience. A quantitative urinary flow system amenable to home and hospital use will offer diagnostic and therapeutic benefit to the millions of patients suffering from a wide range of urologic and nephrologic disorders. This system will both help patients understand and improve the management of their disease, while providing enhanced information for rapid decision making by health care providers.

Project Background: Millions of patients in the United States and worldwide suffer from both upper and lower urinary tract diseases altering urinary output. To manage these patients, both acutely and chronically, understanding the dynamics of urinary output in terms of the flow rate of urine generation, and the total volume of urine produced over time is critical. For patients with chronic diseases in particular, quantitative measurement of urine output versus time by a simple means would go far to improve both patient understanding and self-management, as well as provide enhanced data for health providers to rapidly make decisions improving therapy. Presently no simple system exists to do this. Additionally, when internal catheterization for urinary drainage is needed current catheters are uncomfortable and have a notorious level of infection, with catheter associated urinary tract infection (CAUTI) occurring in up to 20 to 25% of patients! - being the most common cause of healthcare associated infection (HAI). The uroSMART system will address these two unmet needs improving care, reducing morbidity and mortality.

Requirements: Step1: Get up to speed - Team will research current urodynamic methods (largely hospital based); and catheter systems (internal and external) to outline gaps and limitations. Team will have the benefit of work done by a prior senior design team on the catheter aspect of the project. Step 2: Design and build urinary flow module - A small flow sensor that may be sterilized or disposable with digital capability to communicate to an app for phone or computer-based use. Step 3 - Design and build a digital urinary volume system - to measure urine volume collected directly (direct urination) or via catheter bag (catheter drainage external or internal), with a timing system measuring urine accumulation rate (for either external or internal drainage); and total urine output. Step 4 Residual urine determination system - simple sensor to be placed externally above the bladder to provide semi-quantitative information as to residual urine retained post voiding (applicable only for non-internally catheterized patients). Step 5 Neocath – improved internal drainage catheter with features of: matched tissue compliance for reduced abrasion and pain, reduced infection potential utilizing anti-infective polyurethanes - to be provided to the team. Step 6 – System integration - Data collection, Phone app, Heads-up display and Report generation – Integration system/app for use on smartphone or computer/heads up display integrating all sensor elements displaying: voiding volume (external), residual retained bladder volume (external), urinary output vs time, flow rate (internal use), output or flow rate graph vs time and total urinary output per 8 or 24 hours. Module will log data, generate useful report, communicate to providers/EHR.

This project aims to design and develop a cost-effective, configurable, and vacuum-compatible illumination and imaging system tailored for precision metrology in semiconductor environments. The system should support diffraction limited imaging, and variable working distances. The full list of specifications are in the attached PowerPoint file and includes a wavelength from 800 to 875 nm, an NA of 0.032 and a full field of view of 0.85 mm.

Steer by Wire is a form of steering that eliminates the mechanical linkages of a traditionally steered vehicle, replacing them with an electronically actuated steering rack driven by a set of motors. This system has been in use on aircraft and utility vehicles like forklifts for years but is just now starting to enter the market of production cars. It is currently available on a few commercially available automobiles, such as some sports cars from Lexus and BMW models and larger trucks like the Tesla Cybertruck. Automotive manufactures are increasingly interested in its use in autonomous and self driving systems; largely due to the precise control and because the steering ratio can be actively changed based on driving factors, such as speed or terrain. Please note this is not SAE-exclusive nor do you need SAE experience to be prepared/eligible and background on technical elements, objectives and goals.

This project will follow the industry design process to design, build and test an automotive steer-by-wire system comparable to ones used currently in industry, elegantly combining electronic, mechanical, software and control systems. This system will be put on a former year's Baja SAE club car to test and gather data comparing ergonomics, driver control and capability and vehicle maneuverability. Emphasis on overall system safety and a clear understanding of potential failure modes should be present throughout all stages of design.

Project Objectives
- Design, build and test a working steer-by-wire system
- System should show the test car has increased maneuverability and turn radius.
- Decreased steering effort and better general ergonomics for the driver.
- System should prioritize safety and have failure modes in the event of an issue.
- System should be well documented enough to have future potential for integration into a University of Arizona SAE competition Baja or Formula car.
- Steer-by-wire system should show good understanding of current automotive technologies and have applications, where possible, to current industry cars that utilize this system. Trade studies should be done of current applications of this technology.
- Project will culminate in a research paper to be published and presented at ITC in 2026 by the team.

Stretch Goals
- Variable steering ratio based on different speeds.
- Advanced sensor/telemetry equipment integrated into data collection.
- System will entirely eliminate the need for any hand-over-hand steering.
- Team should conduct interviews of past competition drivers to determine what an ideal steering system would look like for an endurance race, and highlight any issues had in the past that this could potentially solve.
- System should be useable for either front, rear, or all wheels.

Project Goal/Summary: The goal of this project is to develop an improved Cardiopulmonary resuscitation (CPR) training system that will enhance and optimize trainee learning as to the key components of CPR compression needed for CPR success and the saving of lives. The envisioned system will improve training as to correct hand position, depth, force and timing of chest compression, while simultaneously providing digital feedback of all parameters as well as visual evidence of resultant blood flow. The system will log trainee performance, changes/improvements between training sessions, generate a report, allow for inter-trainee assessment and comparison – all means of providing feedback for reinforcement and improved learning. Providing individuals with an enhanced CPR training system, affording instant feedback of the essential elements of CPR maneuvers, movements and procedural elements will ultimately improve resuscitative efforts and go a long way to save lives. Hence, doing CPR right is Life.

Project Background: Cardio-pulmonary arrest (CPA) is a life threatening, not uncommon event which is associated with significant morbidity and mortality. Cardiopulmonary resuscitation has been shown to be lifesaving for CPA. In the U.S. more than 400,000 out-of-hospital CPA events occur annually, with only 40% of victims receiving CPR, often times poorly performed. While initially advanced as a combination of compression and breathing, current CPR has been streamlined to be one of “compression only,” notably through seminal work performed at the University of Arizona. Current American Red Cross and AHA guidelines outline how to perform CPR and provide training courses for certification. Despite this, CPR training is often limited and with inadequate feedback to the trainee. The most common tool utilized to train individuals is that of a CPR mannequin or dummy. These devices while attempting to appear lifelike do not provide the feedback, in a quantitative fashion, as to the appropriate location of hands/position; the frequency, force and depth of compression, all necessary for effective blood circulation in the compromised arrested patient. Further, visual means of instantly evidencing performance and accuracy thresholds, as well as visually recognizable blood (fluid) flow are lacking. The current project aims to overcome these limitations and advance a new system to enhance overall training.

Requirements: Step1: Get up to speed - Team will research current CPR methods, training requirements, mannequins/dummies and other facsimile tools currently used and outline gaps/limitations. Team will have the benefit of work done this past summer by a range of medical students under ACABI on this project. Step 2: Design and build chest force displacement unit w contained sensors – a modular pusher plate/spring system with appropriate/tunable resistance (to mimic a range of chest stiffness) will be fashioned with equipped force sensors (strain gauge, load cell, piezoelectric or equivalent) capable of instant digital readout. System will be designed to function as standalone or placed in the chest cavity of a rubberized mannequin. Step 3 – Design and build a hand/finger placement touchpad system – designed with sensors indicating correct finger placement and contact for a range of chest configurations – male and female. Step 4 – Design and build blood (fluid) flow system – a visual transparent tubular facsimile of the carotids, incorporable into a mannequin, will be fabricated with contained mock blood to visually depict blood flow coordinate with correct compression. System may be electrically pumped synched as to flow rate with force/depth of compression to avoid need for direct mechanical coupling to force/compression unit. Step 5 - Data collection, Heads-up display and Report generation – A readout display means with actual vs optimal performance threshold indicators will be fashioned (consider LabView), system will allow serial as well as inter-trainee comparison and report generation.
