Preliminary Detailed Design Review: P18001 11-14-17

Agenda Team Vision Feasibility Risk assessment Drawings Concept with pressure sensor Concept with relays Budgeting Prototyping Tre’s prototype Detailed electrical drawings Design flowchart Testing Feasibility Sensor testing plans (relate to risk management) Any sensor test results Simulation for strain gauges BOM Plans for next phase

Team vision What we intended to do: What we accomplished: Investigate concepts from Pugh Diagram 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 Natasha

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.
