We are building silicone cover solutions to prevent water from damaging electronics in power wheelchairs. We are a team of 4, comprised of 2 technical business students, a computer science major and a very talented industrial designer.

Step 1: Finding an Opportunity
Our journey began when we were introduced to Ryan, a recent UIUC graduate and power wheelchair user himself. We heard unbelievable stories of his multi-thousand-dollar machine simply powering off in the rain because of circuit leakage - and we could not believe it. Ryan resorted to literally using a ziploc bag to protect the electronics and avoid being stuck helplessly in the rain, banking on kind pedestrians to assist him in getting under a roof. It didn’t take us long to commit to embarking on this semester long design challenge, and trying to help Ryan find a sustainable way to stay dry in the rain.
Step 2: Scan Area Needed for Protection
You will first need access to an iPad and a Structure Sensor. Download a 3D scanning app for Structure Sensor from the iPad app store. Finally start capturing precise 3D models instantly. Check out Structure Sensor Tutorial App linked below for some great scanning tips.
A few tips being:
-Scan things at a comfortable height
-Give yourself 360 degrees of access to the object you are trying to capture
-Scan 1 meter from subject
Step 3: Print 3D Scan of Arm and Joystick
Thanks to the accuracy of the 3D scanned replica of the powerwheel chair arm and joystick a form fitted skin could be made by using the information from the Structure Sensor. Most applicaitons you will use to capture the 3D information will output a file that is compatable with Fusion 360. Import the file to Fusion and create a two part mold with holes where youll want the silicone injected.
