Another goal was to complete block diagrams to layout the hardware, software, and theoretical implementations of future design work. Additionally, we needed to deliver our first oral report and begin procuring hardware through confirming the shipping of the prosthetic hand and acquiring purchasing forms. <\/span><\/p>\n<p>&nbsp;<\/p>\n<p><b>Work Accomplished<\/b><\/p>\n<p><span style=\"font-weight: 400\">The past week has been very productive for our team. We performed and generated our first oral report and outlined where we currently are in the design process. We identified how we can purchase hardware by discussing this aspect with Dr. Walker and are hoping to move forward with initial hardware needs soon. With this in mind, we researched possible hardware for our base-case design. This began with the creation of a block diagram for the hardware and circuitry pathway we hope to implement within our system. By visually studying this pathway, we were able to identify two major hardware needs, an independent EMG sensing microcontroller and an integration platform. Within those two schemes we researched possible solutions mostly within the arduino spectrum for ease of use. A patent search was completed with only one other force-based prosthesis controller identified, but the space that was discussed within this patent should not be infringed upon by our work. The literature review was continued with several resources identified regarding the major components of the project. This also allowed for the creation of a possible algorithm block diagram and identification of possible intent interpretation pathways. We also had a successful meeting with our advisor and discussed other possible action steps over the coming weeks.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><b>Work Backlog\/What Went Wrong<\/b><\/p>\n<p><span style=\"font-weight: 400\">Prosthetic arm has not arrived yet<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Prosthesis is still on its way, should now arrive by the end of the week<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Is coming with a charger that should work but is borrowed &#8211; we will have to be very careful with it<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">EMG experimentation and data collection have been postponed<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Team decided to delay lab work until we receive the arm and see what we\u2019re working with physically<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">This step will now hopefully begin after we get back from Thanksgiving break and have the prosthesis<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">Still trying to get in touch with someone to submit request for expenses\/ordering of materials<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Visited the office last Thursday and the appropriate contact was out for jury duty &#8211; we now have our parts list ready and will check back after break<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><b>Plans for Next Week\/How to Accomplish<\/b><\/p>\n<p><span style=\"font-weight: 400\">Through the rest of the semester, we plan to:<\/span><\/p>\n<p><span style=\"font-weight: 400\">Update Hardware Block Diagram to better represent process<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Change colors to differentiate between different components<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">Reach out to professors in similar fields<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Email Dr. Goldfarb<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Email Dr. Withrow<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">Create Feedback loops for velocity vs force based prosthesis<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Create new block diagram including feedback loops similar to those seen in system physiology<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">Look into possibilities for phantom muscle signals<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Perform literature review of topic<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Reach out to experts in the field<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Brainstorm possible solutions<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">Investigate sampling frequency of arduino <\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Determine frequency of EMG<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Insure that the sampling frequency of the arduino can be double that of the EMG frequency<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">EMG hand-posture investigation<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Submit purchase request for materials<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Obtain required materials including ECG pads<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Coordinate time to use BME 4900W lab<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Develop methods to collect data<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Determine data needed to perform investigation<\/span><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Previous Goals \u00a0 This past week, one of our goals was to continue our literature review, which was extended to include a patent search, to continue to build a base of knowledge on the relevant subjects and begin brainstorming possible design routes.
