Meeting 2/15/24

Team Meeting 2/15/2024

Begin: 6:00pm
Place: Pomerene 260
Planned End: 9:00pm
End: 7:50pm

Agenda

• Talk about reworking bot to use 4-bar
• Discuss APP R05-1: Initial Project Schedule
• Discuss APP R05-3: Agendas and Notes

In Attendance
Brian, Griffin, Drew

Sam is sick

Notes

• Formulated a plan for completed upcoming APPs.
• created a plan for completing the project schedule over the weekend on GitHub
• created a time sheet format and testing log
• submitted the first parts order
• discussed 4-bar for kiosk high and low buttons, and the fuel levers. Luggage will be handled by a little holder on top of the 4-bar mechanism that acts like a dumptruck. We will be able to raise the 4-bar and the luggage will just slide out.
• Brian will draw up a CAD model to better visualize functionality. The team will go ahead with the rack-and-pinion design for now

To-Do

Project Schedule

• Griffin: half of APP assignments
• Sam: team meetings
• Brian: all project milestones
• Drew: APP R05-2, documentation
• Everyone: add time from this week into the appropriate time sheet

APP R09-1: Final Report Outline

Team Meeting 3

Mockup & Solid Model

• Base is laser cut out of plywood
• Laser cut materials:

• Acrylic can crack easily and it is difficult to modify once it has been laser cut, so we plan to use plywood.

• Laser cut pieces should be put together with fasteners. Avoid glue when possible.

• Tolerances are not absolutely critical for the chassis so the 0.004" kerf shouldn't be a huge issue

• Proteus weighs 432g

• Robot has good ground clearance on the steepest ramp even with 2.5in drive wheels (see prototype Onshape version Ground Clearance Test 2.5in wheels)
