Notes

Scrumming today: Wells, Roche, Battis, Eacho, Baum

• Lathe (Wells)
  • Have milling attachment on and working!

• Practice Arena (Donald, Battis)
  • Low goal and one vision target are set up in the new bookstore, and the truss and zone boundaries are measured and marked with electrical tape.
  • The high elements are in the atrium, waiting on a shopping run by Mrs. Brown to get the last few pieces to finish the high goal.
  • Mr. Battis has been chatting with the athletics department and custodial services about getting us some time in the gyms to practice with high elements, driving, etc. Stay tuned.

• CAD (Niles, Joey)
  • KOP committed to the GitHub repo (beware of your next sync!)
  • Robot is being modeled, with an eye to space allocation

• Drive Station (Battis)
  • Second laptop has arrived and needs to be configured
  • We need to start work on a (solid) drive station that includes the laptop and joysticks.

• Drive Strategy (Eacho)
  • Had some conversation with Coach Young
  • Have to be able to catch to stand out (possibly better to catch every time and only be able to shoot 1-point than to catch every other time and 1-point it)
  • Weighing the pros and cons of 1 vs. 10-point goals
  • Need to do some timing for various operations (catch, throw, shoot)

• Bumpers (Baum)
  • Cutting the lexan spacers for the bumpers (almost all done — will be done by the end of the day)
  • Next step is to drill and then fold

• El Toro (Eacho)
  • “Horn guards” (a.k.a. arm supports) are cut, drilled, etc… next step is assembly
    • need to work out connection on motor end — should use the motor mount screws NOT shaft!
  • Working on the axel/pivot, have roughed out the pivot design — looking good (ETA by Friday)
    • need a bracket for the CIM mounts so that they can swivel
  • Thought process right now: let’s get El Toro mounted and toro’ing, so that we can think about how to pivot it up and down
  • Working on making key ways (have to make the tool we need to do it… Wells is on it)
  • Need to commit on a toro length
  • Have 2 batches of PVC with different inner diameters — keep yellow and white separate (and paired)
  • Window motor disc with a pitman arm (pusher) to push the El Toro pivot

• Punch list for Thursday
  • Arm supports (Horn Guards) for the rollers – Eacho/Wu
  • Passive CIM mounts – Roche
  • Pitman Arm – Alipour
  • Keyshaft adapter – Wells
  • CAD for space claims – Battis, Lyons, Stanton
  • Detailed breakdown for catapult
  • Practice Arena – Donald
  • Toss the robot on the package scale to get a sense of weight
  • Set up new driver station

• Shopping List
  • 12x 8-32 x 1.25″ for “horn guards”
  • Current awaiting the arrival of…
    • Gearmotor and mounting brackets
    • Hubs, window motor mounts and hex shafts
    • Absolute shaft encoder

Priorities

Housekeeping

• Clean up after yourself
• Help teammates clean up after themselves
• We don’t leave until we scrum… we don’t scrum until the shop is clear
• Half-finished projects go on shelves, not the floor
• Scrap is only useful if it’s stock, stock is only useful if it’s organized
