As a result of the sheer amount of time all of us were putting into the project itself, as well as making sure that all of us were simultaneously staying on track to graduate, updating the blog has become a back-burner priority. And instead of acting like these updates have been coming all the time, from here on out the posts will simply be back-logged a little and a condesnsed discussion of the different challenges and solutions we generated.
So without further ado, this is the progress we made at the end of the winter quarter:
Following up another week of little physical manifestation of progress, we decided to start cracking on a physical prototype. After analyzing some models we found in our readings and discussing the advantages and short-comings of each design we moved forward and quickly built a prototype. THe material used was quarter inch foam-core from which we fashioned 2 rings and a hand pad.
By running a thin wire from the Distal Phalanx (tip of the finger) down through the Proximal Phalanx (the bone that connects the finger to the palm), then through a pad that covered the palm, we were able to test the reaction on a relaxed finger that existed, when tugged on in this configuration. We found that this design was extremely successful as seen in the video:
Having moved into the new lab, we spent the remainder of the week setting up our work stations and filling out paper work to make sure everyone had access to the tools and equipment we needed.Following another short conversation with our mentors and advisors we began to do an analysis of finger models and diffrent existing methods of actuating finger motion. We drew some inspiration from the Open Hand Project as prosthetic limb movement tackles a similar subspace of mechanical actuation problems as we do.
We also came up with and framed our new logo! Introducing "MAGgy"!
This week was our first back on campus. We met with our adivsors and spoke briefly on the direction that we want to see the project progress in. We acknowledge that we still have an extensive amount of research to accomplish before we really begin to grasp the problem at hand.
We spent most of the week look for documentation and academic research papers on topics pertaining to this project. It we agreed that this was to become an affordable everyday use system, not a reabilitative exercise machine, we also overviewed the demands this put on our system requirements.
