Mems 411: Safely Capturing Giant African Pouch Rats, Anthony Brown, John Christensen, Jared Harrison
Mechanical Engineering Design Project Class
We were tasked with designing a trap to safely capture Giant African Pouch Rats. The traps are used in both urban and rural environments that include city streets, basements, farms, river beds, and bushes among other locations. Pouch rats are much larger than most rats and are a very ferocious species; they will harm themselves if there are any non-smooth surfaces when captured. It is very important that we designed a trap with this safety top of mind.

Mechanical Engineering Design Project Class
Our goal is to design a giant pouched rat trap that meets the customer needs from professor Stan Braude. The giant pouched rats are to be breed and trained to find land mines. Therefore, the rats must be captured in good condition. However, giant pouched rats are not passive once caught and tries to escape every way possible. In the past, with traditional trap wires, they tend to get caught in the wire and hurt themselves. Our solution offers a completely smooth inner wall of the trap to prevent damage to the rats, while improving on the functionality of the …

Mems 411: Rowing Force Plate, Mae Hubel, Taylor Southwick, Miles Petersen
Mechanical Engineering Design Project Class
The Rowing Force Plate is a device that is designed to measure a rower’s force
over time so that they can understand how hard they are rowing. Most rowing
aids communicate the speed at which someone is rowing, which is variant on water
speed, wind speed, and other inconsistent environmental and situational factors.
Force, however, can be consistently measured and is a better indicator of effort a
rower is exerting. Other products that measure force do exist, but use complex and
expensive technology, unlike our design.

Mechanical Engineering Design Project Class
The volleyball setter has certain patents that utilize some sort of rotational component or is a stationary platform that the ball rests on before the player hits it. Our design is different because it utilizes the mechanical properties of springs to propel the ball forwards. We had certain specifications to meet to allow the volleyball to be natural in its trajectory and able to be shot efficiently and effectively. Some specifications required positioning adjustments and some defined how the ball should be propelled through the air. We also had parameters involving cost, weight, and the repeatability of the mechanism to …

What is often thought of as a rat trap is often in reality a mouse trap, or a trap designed to catch small rodents. Rats can be quite large and catching them without harming them can be quite difficult. Current market solutions generally either kill or harm the rodent which is not acceptable for our client's needs. While there are some solutions on the market, they fall short of the needs of our client which is more specialized due to the size of rodent they will be capturing, the circumstances surrounding the capture, the number of rodents our client needs …
