Overview of Status of Analysis, Design, Fabrication, Tests, etc.
This week team 6 continued work towards implementing final design decisions. A third revision of the enclosure and all ancillary parts needed to assemble the final design were created in CAD and given to Tom to start fabrication of aluminum enclosure. Raw material was salvaged from scrap material supplied by Tom and machined into the required dimensions by the team and will be used on the CNC by Tom.
Further cleanup and tying up of loose ends continued on the software side. The team worked closely with ARMOR Lab this past week, comparing device performance to their benchtop setup and ensuring data formatting was cohesive. The most exciting development was a test of the EIT device using ARMOR Lab’s post-processing algorithm. Data collected using the device was used to create a conductivity map of one of their sensing skins with great results.
Accomplishments from Previous Week
Full 32 nodal resistor network ready for testing (A/B/A comparison to Ken’s setup)
Finalized enclosure for machining and prepped materials (6061 Al)
Verified functionality of device on actual film and captured conductivity map
Collaborated with ARMOR Lab to ensure proper data formatting for post-processing
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Finish up report and poster (All)
Assemble final device (all, Aaron)
Clean up and comment code (Max, Jacob, Matthew)
Integrate all UI components (Jacob)
Functionalize code (Max)
Optimize data storage speed
Add streaming functionality
Continue performance characterization (All)
Compare data to ARMOR Lab setup using control resistor network
Gather data and video in action on Kevlar dummy
Characterize and document functional range, error, and non-linearity of device
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
(5/25/18) - Ken was satisfied with the prototype’s performance in demonstration to Navy.
Ken expressed interest in easy access to SD card if it is easy enough to do (i.e. don’t kill ourselves over it); the team has taken it into consideration.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
(5/23/18) - No significant comments/concerns.
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
“Is it drop proof?” - Mike. Not a major concern of Ken’s, and he is happy with its current ruggedness. We do not have the resources, nor time to extensively quantify robustness.
Risks and Areas of Concern
Data retrieval (not really a risk or concern, just last thing needed to implement)
Resources or Information Required but not Available
ADC driver autoscan functionality, still waiting on new information. Planning on delivering device as is, without autoscan.
Schedule
