Team Meeting
- Summary for Lunabotics Website will be written by Shannon
- Everyone needs slides / parts of deliverables submitted to group on or before the group due date
- If prior commitments need to be done, tell group but plan accordingly
- Dr. Clark would be good to use to check over presentations before we present next time
- We need to have discussions on presentations leading up to presentation date to cover bases on questions we could be asked.
- Ask for help if you do not know something
- Presentation specifics:
- No hands in pockets
- Make sure that you are paying attention when not presenting
- Ordering:
- decoder chips and clocks have come in
- encoders and mounting pieces have not come in
- Next deliverable:
- Things that are already complete will be in the background and intro section
- Why doing project, last year apparatus
- Frame, legs, etc.
- We will be doing sections on things that are still in design and testing phases
- Detailed description of parts
- Prototyping:
- How it works and why it’s a good fit
- What we chose and why
- Part numbers and specs
- Pictures, Flow charts, etc.
- Conclusions: challenges and their resolve. Expected results
- Materials being purchased and already purchased
- Decision Matrix?
- For next presentation:
- More pix, simulations and diagrams
- Individual parts in on time
- More practice and discussion to field question
- More extra slides with more substance to field questions
- Next meeting is Sunday at 12:00 PM
- Rob and Devin work on Simulink Simulation for Power
- Seth and Fadool: Motor spin at variable speeds with Buehler ring
- Shannon and McKenzie: Four Bar physical model of excavation
- What everyone is doing for Deliverable / Presentation:
- Seth and Fadool: Building Controls
- Shannon and McKenzie: ProE analysis and Excavation
- Devin: WiFly
- Rob: Power Systems
- Over Thanksgiving break everyone needs to have their parts done to be able to edit
- Meeting Sunday after Thanksgiving, all parts done, editing process begins
- 8:00 PM
Team Meeting
- Staff meeting Tuesday at 2:40 PM.
