5 Case Studies Of Senior Design Project Ideas Mechanical Engineering

1. Case Study 1 Automated Prosthetic Hand Control System

Students at Virginia Tech built a prosthetic hand that works with muscle signals from the user’s arm. The team used sensors, small computers, and servo motors to control finger moves and grip styles. Their design lowered the cost of making the hand by 40 percent compared to current options while also making it faster to respond. The project showed the chance for low-cost, high-quality prosthetic hands that could help people who lost a limb around the world.

2. Case Study 2 Solar Powered Water Purification Device

A team from MIT made a small water cleaning system for villages without clean water. The device uses solar power and strong filters to clear bacteria, viruses, and chemicals from dirty water. Their test model cleaned 50 liters of water each day with only solar power, so it worked on its own without fuel or power lines. The project solved an important health problem and showed how clean energy can work in real life.

3. Case Study 3 Autonomous Drone for Agricultural Monitoring

Students at Stanford University built a flying robot system to watch crop health and guide farm watering. The drone used cameras, GPS, and heat sensors to spot weak plants and check soil water across big farm areas. Their system covered 100 acres in one trip and gave farmers easy reports on a mobile app. The project showed how new tools can change farming and help raise food growth.
