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
