Managing priority list, big picture, deadlines

Phase 1: Prototyping

  • Try Spectrum’s PVC prototype kit
  • Start CAD while prototyping - just to map things out and get a better vision
    • Blocky
    • Expected to change
  • Design Reviews
    • Structured reviews
    • Internal
      • Generally every couple of days
      • Go through checklists and make sure everything has been reviewed before moving onto the next stage
    • External
      • Have at each stage of the process - like 3 times or something?

Phase 2: Design Concept

  • Simplicity (num of motors, combining parts, degrees of freedom, foolproofing the assembly, etc.)
  • Manufacturing feasibility/process (designing within our manufacturing means)
  • Geometry (pathing, dead spots)
  • Packaging
    • Max extension
    • Maximum height
    • Frame perimeter
  • Layout of mechanisms
  • Checking calculations
    • Motor math
    • C-C distances, pathing and accessible tensioning
  • Power budget (num of motors running at once, num of slots being used)
  • Electrical integration
    • Sensors
    • Wire routing
    • Space for electrical components
  • COG/tippiness
  • General maintenance (eg. avoid needing to take a lot of the robot apart to do a replacement)

Phase 3: Design Details

  • Fasteners
  • Hole sizes
  • Clearances
  • Maintenance (hand access, tool access, modularity, etc.)
    • Longevity?
    • Supports/cross members and weak spots (thickness/snapping, orientation of cheese holes, etc.)
  • Mechanical
  • Look at switching to REV MAXplanetary
  • Give swerve motors back to Leia for defense in drive practice
  • Manufacturing and Assembly
    • Part drawings for parts that are manually machined
    • Assembly drawings, yay!
    • Map out or cad spacers
      • Maybe print custom length spacers? Would reduce modularity but would make assembly more foolproof
    • Spreadsheet tracking for parts needing to be manufacturing
    • Have a BOM as we go
    • New tools (allen keys, ratcheting wrenches)
      • Organized!!!!!!!!! Placed strategically
    • Make full spare systems (e.g. intake)
    • Teach more students how to CNC
    • Do CAM online and remotely
  • Manufacture in assembly order
  • Design leads determine assembly order in a master spreadsheet
  • Purchasing
    • Have more people involved
    • Subteam leads responsible for their own tabs in spreadsheet
    • Have list of people who are willing to put things on credit cards
    • Diligent about part numbers and quantities
    • Order before the season starts
      • Metal, lexan
      • Rivets
      • Washers
      • Bolts (look at grades, can ask Andy)
      • REV MAXplanetary
      • More yellow organizers
      • 3D printer?
  • Electrical
    • Label everything
    • Have a student who knows electrical systems be involved in design
  • Categorize
    • Must never fail (chassis, superstructure)
    • Shouldn’t fail, but can be replaced easily if it does

Random other notes

  • Have clearance charts up on the walls (CAD and manufacturing)
  • Do test holes in aluminum and lexan to find the right size for us
    • Bearings (press fit)
    • 3/16 rivets
    • 10/32 clearance
    • 8/32 clearance
    • ÂĽ-20 clearance
  • Offseason Projects
  • High priority (Next Monthish):
    • Integrate new CTRE system in 2023 robot before STEMley
    • Tool chest reorganization (Color coding, tool container change - Eden led)
    • Order tools in the week of Sep 24-30 (Brandon)
    • Drawer separation
    • Filtering through useful tools (Quinton)
    • 8-32 & 10-32 reorganization
  • Mid priority(Definitely do before build season):
    • Design lead elevator project
    • Experienced student projects (Kenneth)
    • New student swerve project (Daniel led)
    • Modular weights, used for future prototyping
    • Practice improved design process
    • Regular design reviews
    • Drawings
    • Robot cart upgrades (hold tools, batteries, driver station, etc)
    • Better autonomous reliability
    • Logging variables for the robot
  • Low priority (Expect to do before build season):
    • New 3DP tube insert (New student, Brandon led)
    • General workspace organization
    • Reference sheet with color codes, allen key sizes, wrench sizes, tap sizes, clearance hole sizes (Eden)
    • Testing/maintenance autos
    • Update reference documents

Team Suggestions Consensus

Good

  • Robot cart tools
  • Off limits when building robot, use when maintaining
  • Mark differently to pit tools
  • Clecos
    • Open to using them, could be useful
  • Swapping Andersons for WAGOs
    • Worth a try
    • Could be useful for quick fixes
  • Tube plugs
    • Order as needed
  • Bonded wire
    • Buy whatever is cheaper
  • Buy new brushless motors that come out (Probably WCP)
    • Not too concerned about motor issues as we can revert to old motors
    • Will need to budget out a good amount for
  • Use CacheCAD
    • Interfaces with gdrive
    • Looks good!

Maybe

  • Mini lathe
    • Useful if there are leftover funds

Not right now

  • Ferrules for small wires
    • Not necessary as per expressed by Electrical team
  • Chop saw
    • Not necessary
  • Colson drive wheels
    • Stick with tread
    • More regular maintenance, hole punch screw holes, get jig
  • Mini mill
    • Not worth the money currently
  • Tooling in organizers
    • Not necessary
    • Workflow: take out organizer, see red, get red wrench and red allen key
