Final Update: Week 10

We had our presentation today! After a long night of working out the kinks and practicing we presented our PowerPoint about the Smart Suit at 8 a.m. today. It was quite early but the presentation went smoothly. Since Air Products sponsored us (thanks!) we left our project so it could be handed off to them. After ten weeks we are very proud of the progress we were able to make. We came in knowing nothing but we learned a lot about electronics, mechanics, and programming. We also learned how crucial the design process is. Engineering isn't just about solving problems, it about solving problems with limited resources.

Quick Update: Week 9/10

This is a quick update right before we have our presentation on Thursday. We did some tests in water over the weekend. Unfortunately we could not use the Drexel high dive, so we had to resort to visiting a friend's house to conduct the tests. The other bad news is that we did not test the entire system when jumping in the pool. Since the waterproof box is not covered under the outside fund, we felt as if it was unnecessary to drill a whole in a box which we would only be using as a proof of concept, only to end up paying for it out of our pockets. But there is good news of course!

The good news is that everything is working pretty well together. As you saw in the previous posts and videos the Smart Suit was functioning well even with the addition of the new bladder and SD card shield. The good news that I want to add for this weekend is that we were able to successfully get data from Artemis jumping in the pool. The following video shows a short jump into a pool, yet when we looked at the data the point of impact stuck out.

Weekly Update: Week 9

With the deadline quickly approaching we have reached our goals that we set in the beginning of the term. As you saw in the Memorial Day update, we had a working SD card shield. We were also able to make the valve on the new bladder connect to the tube from the CO2 canister. As you can see in the following video, that the whole system is integrated and working!



Since we have a SD card we started doing some tests with the device on our bodies. We conducted several tests including walking, jogging, sprinting, and then walking and sprinting on stairs. The following video captures one of the test. Along with the video is a line graph of the acceleration data recorded.




If you compare this data to the data from the graph on the last post (Memorial Day), you can see that there is only one line instead of three. The previous graph had three lines because it was recording the x-, y-, and z-axises. The new graph only has one line because the data from the accelerometer is going through a low-pass filter first.
