Prototype Testing and Evaluation

Our prototype gave us a good idea of where we stood in relationship to how close we were to having a working solution. At this stage the majority of the electronics were working individually, they just needed to be combined. As for the mechanical side of things we saw that this was our weak point. We had an exterior housing that worked nicely to house the OLED screen and keypad so we knew the outside was all set. The interior components were where we fell short. The adjustable lock clasp's original design did not work as we intended it to.

The original design was to grab the lock along the longer side as we would have more room between the two walls to mount the springs and nuts. However this design did not work. When we tried this design on the lock by rotating it by hand, it would just slip off of the lock and not turn it. This was a serious problem since we were not actually able to lock or unlock the door so we knew that we were going to need a design modification for this. Then we also realized that we needed a mount to attach the servo to the door and we also realized that we should have a case for the buttons to make the design look cleaner.
