Current StateCurrently on track to meet our mission objectives and cover all customer needs

Unpredictable to know whether or not sensors will “walk the walk”

All major subsystems good to goDr. Phillips gave approval to EE componentsMet with Sara one week before DDRTest Fixtures: Mostly done- exploring additional options

Shock and Impact- biggest concern at this point


Current State.. contDesign Activities still open:

Test Fixtures: Will meet with Lamkin-Kennard on Week 1 of Spring quarterNeed to generate ideas for shock/impact testing

Order Components: (Discuss purchase requisition form?) Drawings and Schematics for Sensors/MCUs

Build-Test Activities Needs EE Lab Permission?Acquisition of all items?

Project Plan ComparisonCompare planDifferences and causes?

Main differences: due to our project’s deviation from typical MSD projects (research vs final production)

What would we do differently next time?Try to find a comparable project for benchmarking during week 1


MSDII Project PlanStart up on risk assessment as soon as possibleStart software development and testing soon, so as to enable system level testingTest fixtures earlyAllow for time to re-test in case of erroneous resultsTest overall system power consumption


Risk Assessment Comparison

Differences & Causes H-M-L vs. 1-2-3 Ranking MethodAddition of Total Risk column More detailed technical risks

Sample: Sensor Risks from Concept Design Presentation vs Detailed Design Presentation:



Concept Design Presentation



Detailed Design Presentation



Have we executed any contingency plans?Not yet

Have we added any new risks since DDR review?

Shock/Vibrations- Still unsure P10011 Spine replaces Dr. Brown’s Arm as gold standard- with accompanying risksEffective use of Arduino IDE (MCU/Data/Comm)

Will customer needs be met?If our components perform as advertised!


Individual Team Members Status

What were your personal responsibilities and where are you against your plan (compare to your original plan)? Have you utilized your plan effectively in MSD I and is your current assessment of status realistic? Have you prepared your schedule for MSD II – is it meaningful and realistic? What would you have done differently during the quarter (as an individual) knowing what you know now?


James Stern, ME Responsibilities

Sensor Interface Lead: Limb Kinematics, Sensor Placement, Sensor Configuration.Liaison with Human Interface Team. Sensor Technology Assistant. Enclosure Assistant.


James Stern, MEMSD1 Plan

Research of current sensor tech. to help Cory and JahanaviTest Method Research and RisksCommunication with p10011Test FixturesTest Method BOM

StatusResearch has been completed, and sensors to be tested have been picked for MSD2Test method Risks have been kept up to dateMain Test Method Plans have been discussed and pickedNew test method will have to be implemented for impact testing for sensor durability (Will work hand and hand with p10011)Constant communication has been kept with the Human Interface Team.Test Fixture has been Designed and ready to be builtBOM for Test methods has been completed, and parts are ready to be ordered.


James Stern, MEMSD2 Plan

Order parts for Test methodsStart Building Test FixturesMeet with Dr. Lamkin-Kennard to see her articulated arm for another possible test methodVerify Accuracy of test fixtures with multiple testsStart tests with sensorsIntegrate sensors and microcontroller and repeat tests.Include Human Interfaces enclosures with sensors testing


James Stern, MEA Look Back

Would have tried harder in Circuits 1 so can get more involved with Sensors and Microcontrollers.Would have Started notebook in beginning of MSD1 instead of catching up with notes halfway through the quarterGroup has been amazing and things get done without saying them, could not have picked a better team.


David Monahan, ME Responsibilities

Project ManagerAssemble & execute weekly meeting agendasKeep track of what team needs to do on a week-to-week basisEnsure major deliverable compliance- all bases covered?

Enclosure Lead**Liaison with NazarethSensor Interface Assistant.


David Monahan, MEMSD1 Plan

Research & Benchmark EnclosuresOrganize meeting with Nazareth & expedite communication throughout quarterBe a effective team leader

Ensure team understands what needs to be done and is on task.Ensure communication is facilitated within all aspects of project- members, EDGE

StatusAborted most Enclosure work after week 6 due to P10011 overlap

Refocused research/work efforts on test methodsSpontaneous meeting with Nazareth during Week 2; organized follow-up week 9Authored Test Plan with feedback from more electrically talented teammates Prepared Agenda in advance of each team meeting; Kept track of needed deliverables

Team compiled all deliverables & executed 2 successful presentations


David Monahan, MEMSD2 Plan

Start Building Test FixturesVerify Accuracy of test fixtures with multiple testsFacilitate merging of P10010/P10011 testing efforts Concept Generation: Shock and Impact testingContinue management of teamContinue liaison position with Nazareth


David Monahan, MEA Look Back

Clarify stance with enclosures with P10011 on day 1- rather than allowing for confusion during week 4

Modify Enclosure/Sensor interface positionsDiscuss collaborative testing w/P10011 earlier

Shock & Impact included in MSD1 concept generation Found benchmark or full understanding of “research project” during week 1Used projector starting week 1 during large group meetingsBe more of a “bad cop” when needed

Brian Glod, CEMSD1 Plan

Research and select adequate microcontroller for this projectResearch data storage and PC/MCU communication options and requirementsAssist EE’s (Cory and Janvi) with sensor/MCU interface circuitryManage risks and keep Risk Assessment document up-to-date

StatusUltimately selected Arduino Mega MCU

Dr. Phillips (EE) thought this was an excellent choiceSensor data to be stored on microSD card through Arduino add-onPC/MCU communication through standard USB 2.0 cableMCU has sufficient analog and digital communication buses, protocols, and ports for successful interfacing with all sensors selected by EE’sRisk Assessment document kept up-to-date


Brian Glod, CEMSD2 Plan

Order MCU components (before break)MCU, cables, power supplies, etc (see Electrical BOM)

Become familiar with the Arduino IDEWrite small programs for testing interrupts, ADC and DIO operations, microSD card read/write operations

Work closely with Assis in designing the MCU softwareBreak down the programming into small blocks / modules

Assign programming tasks to Assis and myselfFinalize software system design flowchart

Weekly (?) deliverablesMaintain communication with EE’s for sensor integrationContinue to keep the Risk Assessment document up-to-date


Brian Glod, CEA Look Back

Realize this is a research project from day 1 as opposed to weeks later:

Which sensors are good for what part of the body?What microcontrollers are small and portable, yet powerful enough to perform the necessary calculations and data storage?This project is not meant to design an entire motion tracking system!!

Increased communication with AssisMore microcontroller software design and programming flowcharts may have optimized the MSD I planning stage

I am very impressed with how well this team works together

Cory Laudenslager, EEA Look Back

Would have spent more time on how the sensor technology actually works and how to find position ; Would have saved time in sensor selection.Would have updated notebook continuously in real time instead of in scratch notebook and copying over.
