Wednesday 1/21Scrum Notes

  1. What did I do today?
  2. What will I do tomorrow?
  3. What’s standing in my way?

Driving Practice (Wu)

  • Today
    • Practiced on last year’s competition bot
    • Showed David Baek how to write code, use RobotBuilder
  • Planning
    • Maybe try some driving practice with a shelving unit on top of the bot to get height and weight approximation?

Elevator (Helynna, Niles)

  • Today
    • Working on bottom axle roller — essentially complete, just need to bolted on
    • Top axle
    • Getting ready to VHB bottom assembly to frame (part of the tensioner)
    • Wired a motor, but we need to figure out where it goes
    • CADded up the side pieces of the elevator and laser cut them
    • We _think_ everything will fit inside the height limit (given our present CAD sketch)
  • Planning
    • 4 1/2″ shaft collars — check drawers before purchasing
    • Need to finish the motor connections

Sensors (Wu/Roche)

  • Planning
    • Do we need a photo gate?
    • We just got about 20 limit switches through FIRST Choice
    • Probably want to build cases with roller
    • We can probably figure out what floor the tote is on with only one or two switches — talk quadratures with Wells

2-belt Dimensions (Battis)

  • Today
    • Drew out a 2-belt system, seems like there’s lots of space
    • Tried “dunking” the can with a hammer hook, and there is _a lot_ of force behind it, need to slow it down or make sure we’re just “kissing” the top tote
    • Seemed pretty stable as it hit the top tote (not as much worry about antlers or fenders to keep it from rolling off)
  • Planning
    • Software: need to factor in a counter to bring up a short stack of totes if we have to drop a short stack with a barrel
    • Experiment with larger rollers to reduce angular velocity of the base of the barrel going “over the top”

Chassis (Jane & Thayer)

  • Today
    • Dismantled the new chassis
    • Removed the hangy-downy-gets-stuck-on-things tab — no more getting high centered
    • New Mecanum gearboxes are back-ordered until the 26th today (was the 23rd yesterday)
    • Mr. B has notifications set for when the new Mecanum parts come in stock
  • Planning
    • Jane’s going to hang around and re-assemble the chassis
    • Let’s drill holes (real careful like) to attach old gearboxes
    • Check to see if we can adjust the gearbox/chassis interference with a spacer on the axle
    • Maybe widen the pontoons to put the gearbox on the outer wall of the inner wall?

Hammer Stick (Niles)

  • Today
    • New design ready for 3D printing
  • Planning
    • 3D printing

Sekret Art Project (Eun Soh, Sarah)

  • Today
    • Final design finished by tomorrow

Writing (Jane & Cynthia)

  • Today
    • Spent some time working on essays today, but frustration is running high
    • 2/3 of the way through the first Deans’ List and Woodie Flowers nominations
  • Planning
    • Need some more active help from others to get these DONE
    • If anyone is free or wants to work on this on their own time, talk to Cynthia or Jane

Happy Birthday, Sarah!
