Developing an Autonomous Industrial Vehicle: A team of mechanical engineering students developed an autonomous industrial vehicle that could navigate a warehouse environment without a human operator. The vehicle used sonar, lidar, cameras and gyroscopes for navigation and object detection. It was programmed to follow waypoints, avoid obstacles and operate safely around humans. This type of autonomous vehicle has applications in automating material handling in warehouses and distribution centers.
Augmented Reality Applications for Maintenance and Repair: An interdisciplinary team with members from mechanical, electrical and software engineering developed augmented reality applications to assist with equipment maintenance and repair tasks. Using a tablet or wearable display, the applications would overlay holograms displaying part diagrams, instructions and other information to guide users through complex procedures hands-free. They focused on developing for maintenance of industrial machines, vehicles and infrastructure. The goal was to improve worker efficiency, reduce errors and provide remote assistance capabilities.
Additive Manufacturing of Custom Prosthetics: A group of biomedical engineering students worked with clinicians to design and 3D print custom lower limb prosthetics for specific patients. They leveraged computer modeling, scans of patients’ residual limbs and additive manufacturing techniques to create lightweight prosthetics tailored for optimal fit and function. Designs incorporated features like flexure joints and pressure sensors to mimic natural biomechanics. The projects aimed to prove the feasibility of personalized prosthetics produced via additive manufacturing.
Smart Home Automation and Control System: An interdisciplinary team with computer, electrical and software engineering expertise developed a smart home automation and control system prototype. The open-source system integrated devices for functions like lighting, HVAC, appliance control, security and home automation. It used a central hub and app along with wired and wireless sensors/actuators. Advanced features included remote access/control, integrated voice assistants, energy monitoring and automation rules/profiles. The goal was to demonstrate a robust and customizable smart home platform.
Robot Path Planning and Obstacle Avoidance Algorithms: A computer engineering capstone focused on algorithms for robot path planning and navigation in unknown environments. They developed probabilistic and optimization-based approaches for obstacle detection/avoidance, shortest path calculation and resolution of dynamic or uncertain situations. Techniques included rapidly exploring random trees, A* search, neural networks and genetic algorithms. Results were tested in simulation and on a miniature ground robot navigating mock environments. The work contributed novel approaches applicable to areas like robotics, automation, logistics and autonomous vehicles.
Structural Health Monitoring System for Bridges: A civil engineering team designed and prototyped a low-cost structural health monitoring system for bridges. Sensors were embedded in a small bridge structure to continuously monitor and transmit data on factors like strain, stress, temperature, vibration and crack propagation. Data was analyzed using algorithms to detect anomalies or changes indicative of damage accumulation. Notifications were triggered to alert authorities if thresholds were exceeded. The goal was to demonstrate an affordable solution for remote ongoing assessment of critical infrastructure like bridges to predict maintenance needs and spot issues early.
As these examples show, Carleton engineering capstone projects regularly tackle real-world problems through innovative application of technical knowledge. They aim to prototype new systems, validate design concepts and engineering approaches, and push the boundaries of what’s possible through interdisciplinary collaboration and hands-on project work. The open-ended nature of capstone design challenges students to think creatively and develop comprehensive solutions that consider technical, practical and user-centered factors. This provides extremely valuable industry-aligned experience for students as they transition into engineering careers upon graduation.
