Last day of the hotel breakfast; it hurts to leave it so soon. We started off the day heading to the labs of the Bilbao School of Engineering. We saw their equivalent of Pitt’s makerspace, which was a lot more equipped with huge industrial machines for PhD students to use on their research projects. We learned about parallel mechanisms and their use in both the Balance project and other research with flexible appendages. The flexible appendage parallel mechanisms were delta machines, which are simple designs used to normally pick up and move objects from one place to another. We learned more about the balance project as a whole and got to see it move in person! It is essentially a direct upgrade from the Oreka balance project. It consists of two plates instead of one, which allows for more complex motions like walking. This will further help to be able to rehabilitate patients. The design is still in its early stages, however, and needs to be revised with more up-to-date safety features to ensure both mental and physical safety. We then took a short lunch break at the cafeteria and headed to the hanging bridge. I was absolutely blown away when I saw it. It was bigger than I expected, and the fact it was made so long ago is incredible. It was made with only rivets and no welding, and many changes occurred to the bridge over time. One of the scarier facts is that it is known the cables have to be replaced soon; however, no one knows how much tension is on the cables and therefore cannot find new ones to replace them.
