Project:
Caterpillar manufactures the worlds largest and most powerful hydraulic mining shovels (HMS). Manufacturing these massive machines comes with challenges. Large components need to be moved around the shop for various operations to be performed (ie. machining, welding). The current process to move components around a shop is to use large oversized cranes to lift them from one location to another. This process poses safety concerns due to the size of the suspended loads.

Your challenge will be to design concept an Automated Guided Vehicle to move large components around that would improve shop safety and efficiency.

Requirements:
Must have safety elements incorporated in design (kill switch, safety lights and horn)
Must have carrying capacity of X tons
Must have multidirectional steering capabilities
Must have 150mm of travel in the up/down direction
Must be able to self-navigate around shop

Organization
RBC Sargent Aerospace & Defense
Offering
ENGR498-F2025-S2026

The objective of this senior design project is to develop a fully functional prototype of an industrial-grade coolant management system. The system will autonomously monitor and control coolant level, concentration, and temperature using PLC-driven components. Integration with Kahr’s SCADA platform (Ignition) will enable real-time visualization via an HMI dashboard, alarm notifications for out-of-range conditions, and comprehensive data logging to support predictive maintenance and operational insights.

Key features will include a leak detection mechanism that compares coolant consumption with machine runtime, as well as advanced fault detection through sensor redundancy and plausibility checks. Upon detecting a fault, the system will automatically transition to manual mode, trigger alarms, log the event, and display detailed diagnostic messages.

As a secondary deliverable focused on long-term reliability, the system will also include bacterial culture monitoring and a self-cleaning mechanism for critical sensors. These features aim to minimize maintenance requirements and ensure sustained performance over time.

Overall, final deliverables will include a fully functional prototype, comprehensive system documentation, validation and testing results, and user-oriented materials such as operation manuals and HMI interface guides.

LYCO: TOMI (Lightweight Yield and Crop Optimizer: Tomato Interface)

Project number
26008
Organization
UA Department of Biosystems Engineering
Offering
ENGR498-F2025-S2026
A mobile robot that can navigate crop rows in a greenhouse by pre-programmed path, remote control, or both. The robot will agitate the plants as it rolls by and facilitate pollination. While it rolls and agitate, smart cameras mounted around the robot will scan pest survey stickers (i.e. orange fly paper) and identify with high confidence the species of pest (flies, etc.) and send some sort of red flag to a UI or database if a predefined pest species is detected. The pathing or remote control of the robot should be app-based and compatible on a mobile device like a smart phone. If possible, smart cameras that can do the same pest inspection but in realtime on the plants would be desirable.

Cartilage Growth System Module in Sterile Environment

Project number

Organization
Don and Sherry McDonald Biomedical Projects
Offering
ENGR498-F2025-S2026
Introduction:

Cartilage within the knee joint that is damaged in younger patients due to sports injuries and other traumatic events does not heal spontaneously. Cartilage damage leads to pain, decrease mobility and can eventually progress to diffuse cartilage degeneration and osteoarthritis of a joint. There are no current medical or surgical treatments that restore osteoarthritic joints to their native condition and patients will commonly require joint replacement. Due to the limited longevity of arthroplasty and problems inherent in revision procedures this option is not generally offered to younger patients, who often need to limit their activities and live with pain as a result of a cartilage injury. In order to develop new treatments to regenerate damaged cartilage, stem cells have been used to produce cartilage like tissues. To date these engineered tissues have not had the same histological or mechanical properties as native tissues. One approach to improving the quality of tissue engineered cartilage is to apply a load to the engineered tissues while they are developing. The goal of this project is to design and develop a dynamic bioreactor that can be used to produce tissue engineered cartilage exposed to multiple type of controlled mechanical forces. This will allow further testing of methods to improve the quality of engineered tissues via the application of mechanical loading. A previous team has designed a way to apply an axial and shear load to cultures, however, the design did not allow for application of long-term loading in a sterile environment. The system requirements of the current project will include a method to keep tissue cultures sterile, control the environment that tissue are exposed to during loading (i.e. atmospheric gas composition, temperature and humidity), and control loads applied to tissues.

This project includes the following requirements:
1. Understand Current Assessment Methods: Work with medical educators and surgical faculty to understand the structure and grading criteria of current oral board exams. Gather insights into how these exams are conducted, what types of questions are asked, and how performance is evaluated.
2. Evaluate Existing AI Tools: Research and evaluate existing large language models (LLMs) and AI tools that can simulate conversational or examination-style interactions. Assess their ability to handle complex surgical case scenarios, provide meaningful feedback, and adapt to different levels of expertise.
3. Design the AI System: Develop a system architecture for an AI tool capable of:
o Presenting realistic, accurate surgical cases (e.g., patient histories, physical exams, imaging, lab results).
o Engaging in dynamic, conversational interactions with users, posing follow-up questions based on their responses.
o Avoiding hallucinations that would train the learner with incorrect information.
o Providing constructive feedback on clinical reasoning and communication skills.
o Update based on user feedback.
o Tracking user progress over time.
