What did we accomplish?

  1. design of prototype attachment (frame to wheelchair) solidified
  2. design of prototype attachment (device to frame) solidified
  3. almost all 3D printed parts requests sent out
  4. some purchasable parts on order
  5. complete project plan to outline MSD II
  6. risk management document updated
  7. problem matrix created and tracked
  8. EDGE documentation updated
  9. system architectures updated
  10. all CAD models updated to represent systems accurately
  11. CAD drawings completed for machined parts (except for attachment frame)
  12. initial assembly instructions written for each subsystem
  13. finalized bill of material for entire system
  14. testing plan complete
  15. documentation of design changes since MSD I
  16. update budget sheet
  17. Imagine RIT exhibit description written

What's the Gap?

  1. feasibility analysis: stress on attachment
  2. feasibility analysis: stress on components
  3. CAD model for attachment frame complete
  4. CAD drawings for attachment frame complete
  5. model of full assembly
  6. intended use documents written
  7. begin assembly of subsystems
  8. machined parts machined
  9. fabrication procedure/tooling and jigs developed
  10. Mary Cariola facility tour
  11. Imagine RIT exhibit proposal written

How do We Fill the Gap?

  1. CAD model simulation for stress; benchmarked clamps' load capacity; testing
  2. failure testing on components we've marked as high risk (i.e. ring gear on lever)
  3. finalize structure of attachment frame based on stress analysis;
  4. complete drawing based on CAD model; machine frame at Harabec
  5. combine all CAD subsystems into full system for presentation purposes
  6. create detailed intended use instructions involving which games to play, how to attach devices, number of people participating, etc.
  7. as soon as all parts are in begin assembly for testing immediately
  8. Friday, February 10 machine lever Aluminum housing
  9. research methods of fabrication and begin documentation
  10. Tuesday, February 14 tour is planned for team
  11. proposal written by team by end of February
