Introduction
My senior project was sponsored by Northeastern University and NASA Jet Propulsion labs. It sought to address the problem of rovers and lander being unable to access areas beyond treacherous terrain for data collection. Our solution was to build a two-part system: one is the launcher and the other is the "payload" that houses the sensors. The payload is deployed out over difficult terrain with the launcher. An electro-mechanical tether connects the payload to the rover to transfer data and power. Once the information is received, the payload can be detached and disposed of.
Personal achievement
Besides the contribution to the overall project, I worked on a side project to address the problem of winding up very long lengths of tether in a consistent manner. With every launch, the spool of tether unravels. I modified a fishing reel with custom 3D-printed attachments I modeled in Solid-works to achieve this. Our sponsor really liked my final product and requested to keep it to show to his colleagues. Since he worked with tethered robotics, he found it useful.

Adapted Ride-On Car
Introduction
As part of the Enabling Engineering club, I worked as the project leader for "Go Baby Go", which sought to design a custom ride on car for a child with disabilities. Our target user was a young boy with motor difficulties. His legs tend to flail so this car had to be completely operational by hands with improved security restraints. Our team thought about the best way to re-incorportate the brakes into the car to be used with hands, leg restraints that kept him safe as well as a body seatbelt harness.

Verbal vest
Introduction
Within another project of the Enabling Engineering club, I worked a contributing member of "Verbal Vest". This was a wearable communication device for a our client, Hector, who was a 4 year old boy who lived in an orphanage in Ecuador and had physical limitations, non-communicative autism and partial blindness.
Design
We took many design considerations into account after observing our client and discussing their needs. The communication device would feature pressure sensitive buttons, and would project sounds to express his needs (ie "I need the bathroom", "I am hungry"). Due to his autism and hyper-active tendencies, we decided to adapt a weighted compression vest used to calm children down. He tends to pull things so all the wires had to be tucked away inside the vest. Since his caretakers needed to track the number of times he pressed something, there was a UI. The device needed to be waterproof for when it would get washed.
