1.3. Test Equipment
Focus on any equipment that the team requires to measure specifications but is not available to measure specifications. Discuss this with your Guide. Some examples of specifications that teams could not measure were: measurement of forces, vibration, rf frequency spectrum, field strength, serial communication data accuracy, static and dynamic force measurements, very accurate velocity measurements, rf noise (S/N), complex data acquisition. Contact your Department Guide for any further equipment that may be necessary.

2. msd ii WKS 2-3 test plan – “HOW, WHO, WHEN”
Now that you documented “what” you are going to verify or test in MSD I, you need to document how, who and when. Be critical of your test equipment requirements, any special conditions and so on. Be critical of your testing sequence. That is, test in subsystems before fully integrating?

2.1. Data Collection
2.1.1. Data Collection Structure
Update list of tests to be performed (indicate test # and name, test description and so on).
S1: Size Requirement
Measure wheelbase of the completed chair
S2: Stabilization Bar
Tilt completed chair with team member to required levels
S3: User able to reach multiple directions
Have team member constrained in chair and measure range of motion
S4: User able to reach a 36” table
Constrain team member in chair to drive up to and use a table set to 36” height
S5: Horizontal trunk support
Press on supports and use force gauge to measure applied load
S6: Attach to van with 4 S clips
Securely fasten the chair from four different locations
S7: Support User’s Weight
Test chair functions under load of team member
S8: Battery Life
Completely charge the chair and measure the amount of time it can operate, possibly over several days
S9: Incline Safety
See S2. Also perform full function test on incline according to 7176-14
S10: Full Standing and full seated position
Perform standing and sitting cycle with team member on chair
S11: Controller location from body
Measure distance from seated team member to controller
S12: Neutral mode
Move chair in neutral mode. Already completed as neutral mode is a base function of the provided chair.
S13: Adjustable armrest/footrest
Adjust through full range available
S14: Second controller
Perform all functions available on second controller
S15: Build quality
Ask groups of students and faculty their opinions on the chair aesthetics
S16: Speed range
Measure time to travel set distance at full throttle input
S17: Foldable
Fold all available components
S18: Feet isolated from wheels
Have team member constrained in chair and attempt to have feet contact wheels
S19: Meet budget
Track spending versus remaining funds
S20: Reliability
Perform repeated loaded cycles on all functions
S21: Max chair weight (minus user)
Weigh completed chair
S22: Constraints easily removed or swivel
Have students and faculty attempt to remove constraints and gather feedback
S23: Support user laterally
Have team member constrained in chair and feel if lateral support is holding them in
S24: Removable table
Attach and remove table
2.1.2. Sampling Techniques
“How” to measure and any setup needed?
Many of the Units of Measure are pass/fail on scenarios with no definitive measurements. I those cases the task assigned to the test must simply be completed. A number of the tests also require a user to be constrained in the chair to complete a task. The majority of the setup is for the incline testing and that can be done by going to a ramp with the desired incline or stacking blocks under the wheels of the chair. In those cases a tape measure will be required to gather the required data.
2.1.3. Sample Size
Do you have tolerances on your specifications?
Tolerances have been given using the ideal and acceptable values for each requirement. The number of trials required has not been determined yet.
2.1.4. Reporting Problems; Corrective Action
Any problems encountered will be recorded and detailed by team members present at the time the issue occurs. The team member responsible for the system or requirement that encountered the issue will then lead the rest of the team in an analysis of the failure and possible methods of correcting it.
2.2. Test Procedure, timeline
Who is testing what and when? Are there interdependencies between subsystems (Block Diagram)? Can test equipment enable preliminary simulation of needed signals prior to integrating into the next level of completion?
3. MSD II – WKS 3-10 design VERIFICATION
For and example of completed test results, see https://edge.rit.edu/content/P10232/public/Project%20Test%20Reports
3.1. Logistics
Where are the test results being performed, logged (i.e. project notebook) and documented (i.e. excel spreadsheet)? EDGE team website structure (i.e. document names, file types, and header location).
3.2. Analysis of Data – Design Summary
3.3. Conclusion or Design Summary
Can you explain why a particular function doesn’t work? Conclusions are reported or summarized (i.e. significance with confidence, pass/fail, etc.) as applicable.
3.3.1. Lab Demo with your Guide and Faculty Consultants
Perform each of the specifications and features.
3.3.2. Meeting with Sponsor
See Customer Acceptance above. Field Demonstration. Deliver the project. Demonstrate to the Sponsor. Customer needs met / not met.
