Team Vision for Detailed Design PhaseDuring this phase, our team planned to accomplish the following:
- Finalize mechanical drawings
- Finalize electrical schematics and flowcharts
- Finalize systems architecture and component/subsystem flowcharts
- Create full drawing packages
- Update BOM and budget worksheet
- Prove validity of the design through component and subsystem testing
- Consider lessons learned from MSD1
Drawings, Schematics, Flow Charts, Simulations
Mechanical DrawingsMechanical Drawings of the full assembly were created and drawing packages were assembled for each subassembly - camera mount, frame, and touch apparatus.
The full Mechanical Drawing package of the Assembly frame can be found here.
The full Mechanical Drawing package of the camera mount can be found here.
The full Mechanical Drawing package of the touch apparatus can be found here.
We spoke to DR.Marca Lam as a subject matter expert about the feasability of our current design. The SME feedback form can be found here.
The full Electrical Drawing Package can be found here.
Carbon FiberCarbon Fiber is utilized in this ATLAS design for the camera mount. The Carbon Fiber Work Instruction document, also known as Instruction ARM-01 documents the process to safely work with carbon fiber.
Bill of Material (BOM)The BOM was updated to reflect recent purchases.
The full Phase IV BOM can be found here.
The Budget was also updated to reflect recent purchases.
The full Phase IV budget can be found here.
Test PlansAn example test plan is shown below. The plan can be found here.
Risk AssessmentThe team continued to track the project's risks, and a summation of the major concerns are shown below. here.
Lessons LearnedLessons Learned
- Mechanical and Software/Electrical teams need to be in constant communication
- Giving progress updates at the beginning of meetings will help team members know what everyone else is working on
- Thursday to Tuesday is typically too long to go between meetings even when in communication
- Make sure someone has ownership of every task
- Significant delay caused by no one taking ownership of talking to anyone from Imaging Science
Applications to MSD II
- Meet more frequently, even if it's for less amount of time. Set scheduled meetings times since the class time won't work for everyone.
- Try to predict how the different systems will
integrate together and plan so that they're on a similar
- Mechanical systems shouldn't hold up progress on the Software side and vice versa
- Assume everything will take longer than we originally think
- Check in with SME's frequently and send any artifacts to Gary as soon as they're done
MSD Class Suggestions
- 2018: Nobody uses notebooks/Log books. Google Drive is a legitimate form of documentation and should be viewed as such
- Find a way to let us buy from Amazon
Peer Review FeedbackAfter the Preliminary Detailed Design phase, the team participated in a peer review so that each member could learn how they can improve to best help the team. The main point that each member learned from that review and what they did to address it is summarized in the table below. An additional peer review will be done following the Detailed Design phase.
Plans for next phase
