Future Improvement

For future versions of the project I would like to model the interface between the main plastic body and the remotes metal faceplate. I couldn’t do this in this first version because my remote that I was modeling couldn’t be dissassembled without permanetly breaking it. I would also consider trying to shink the wall plate to more closely fit the remote. Another future goal would be to design the key for locking the back onto the remote to be able to be injectio molded instead of its current state of being metal and screw based.

Transfer Mechanism

Thu, 12 Feb 2026 00:00:00 +0000

Project Goal

Create a mechanism that is able to move a ball through 3 randomly given precision points that can be mounted onto a pegboard. The mechansim must recieve a ball from the previous group and transfer it to the next group.

Hardware Skills Used

3D Printing
Lasercutting
Analytical and Graphical Mechansim Synthesis

Software Skills Used

SOLIDWORKS
MATLAB
Lincages
C++ (Arduino)

Technical Information

The mechanism is a motion generator because it not only moves through 3 specific points, but the dyad at the tip of the mechanism has to only rotate a certain amount before the golfball falls out.

Project Goal

The goal of this project was to create a cart that could be used to test an electric heat pump on a water heater.

Research Goals

The research being conducted is to improve the cold weather efficiency of heat pumps, in particular those in water heaters. As temperatures near the evaporator side of a heat exchanger get below 0 the water that condenses on them can freeze. This freezing can cause frost build up and greatly decrease the performance of a heat pump. Here a coating is in developmenet to greatly delay the time until frost growth and spreading
