This is is a CAD model of a phone holder. I modelled this one because we got new phones, which were larger, and we needed an entirely new phone case. In the past, we have had problems with the phone cord being broken or disconnected from the phone, so I put a plug protector at the bottom so that the microUSB did not get broken in the process of competition.

This is a close up image of the beacon presser that I designed. I noticed that with our old design, as we pressed the beacons, the walls would bend so that we were not pressing directly on the button, rather on the outer shell. To combat this, I thought that if we had a presser on an axis that could stay flush with the surface, it would give us a better chance at pressing them. And it worked.

This is a rendering of the CAD model of our first shooting mechanism. It was a fairly complicated design that consisted of two pairs of spinning wheels run by a series of gears. The wheels spun very fast, but the design just didn't work well enough to keep.
The CAD model played a huge part in building this shooter. As the ball needed to fit almost perfectly for it to shoot right, I used specific dimensioning in Autodesk Inventor to tell the builders where to place the wheels. |
This is the mast that I was co-building for a duration of a few weeks. It was a very complicated mechanism, and was very difficult to make. There was a single chain wrapped around a series of moving and non-moving sprockets. Sadly, it was never actually used, but all that hard work just went into gaining experience. :)
