Begin ordering sensors and parts for testing
Design and build a Proof-of-Concept prototype
Determine sensors to proceed with
Review and update Risk Management chart
Consult Subject Matter Experts
Create a BOM
What we accomplished:
Ordered material for glove portion of prototype
Ordered strain gauges
Identified and ordered another feasible sensor
Integrated functionality for 9 axis accelerometer
Made Electrical system diagrams and schematics
Updated the Risk Management chart
Consulted a Subject Matter Expert regarding sensor feasibility
Drafted a BOM
Designed and built a Proof-of Concept prototype

21. Plans for Next Phase Test switch/relay replacements
Review Test Plan results
Determine final design based on test results
Decide which sensor, MCU, bluetooth to use
Design mechanical implementation of sensor
Research alternate materials for silicone to use for glove
Research manufacturing processes needed for “glove”
Design PCB to reduce size
Adrita: For the next three weeks, the main focus is on carrying out the test plans, so that we can obtain the proper details for the detailed review.
