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
