Scrum Notes > Wednesday, January 15


  • CAD (Niles, Joey, Ryan L.)
    • Have collected all of the parts for the design on on leftmost computer
    • Committing to GitHub
    • Ready to build stuff in CAD


  • Software (Kevin, David B.)
    • Working on sensors (know what we need to do… don’t have time today)
    • Working on sonar range-finder first — seems to be hooked up and working and reading a distance in inches in the software. Whee!
    • Need to find a way to get encoders hooked up to Mecanum — we have bought the parts


  • Wiring (Roche, Ryan A.)
    • New and improved, compact wiring board (with vertical orientation!)
    • Possible lexan housing?
    • Want to know how much headroom the board will really have (need to complete the catapult)


  • Practice Arena (Liu, Brown)
    • Have two horizontal vision targets
    • Can hang the top rail from the bridge in the Atrium


  • Mule Chassis (Cynthia, Jane, Will)
    • Ready to mount gearboxes, but need bolts
    • Wheels are ready to go


  • Kicker (Eacho, Wells)
    • Finished prototype kicker last night
    • Successfully airborne
    • For a kicker, you need to get way under the ball (which means the ball has to be lifted high before being kicked)
    • Argues against using the kicker (underhand vs. overhand when compared to catapult)


  • Catapult (Eacho, Wells)
    • Fiddling with lengths of conduit for the catapult (fitting it within the frame of the robot)
    • Advanced Topics in Physics has run calculations on all of the physics/dimensions for a catapult (shooting distance, tension, etc.)


  • Bumpers (Wells & Wells)
    • Frames are constructed
    • Need to modify the chassis so that bolt heads are flush (to provide full contact with bumper)
    • Suggestion: a sheet of lexan with countersunk panhead bolts instead of hexheads on outside of chassis


  • El Toro (Eacho, Wells)
    • Started ballparking space claims for El Toro, Catapult, electronics
    • Mystery about where the winch straps will go


  • Drive Team (Battis, Eacho, Wells)
    • Chris Young, Channing Weymouth, Neil Cifuentes (and probably Brian Geraghty) all excited about talking strategy
    • Should start coalescing a core drive team to meet with the athletic department and talk strategy (and start practicing driving)


  • Shopping List
    • 24 * 10-32 x 1/2″ bolts
    • Adhesive velcro strips for D-Link
    • More burly helping hand for soldering
    • Need more reflective tape
    • Parts for low goal
    • Bolts for mule gearboxes
    • Conduit for catapult
    • Springs



These will happen no matter what

  1. Drive
  2. Herd
  3. Score >= 6 pts
  4. Bumpers
  • Do this first week, while prototypers prototype
  • Documentation


Prioritize, try to get to as many as possible

  1. Maneuverable (drive train and practice)
  • Mecanum wheels
  • Hold (hardware) a. with potential to shoot if that system comes online b. Loading (hardware) — might not even need this
  • Shoot 8’ (hardware)
  • Some aiming (software)
  • Second robot for driving practice/thinkin’

If Time Permits

Reach goals

  1. Catch
  2. Differential power settings
  3. Vision system
  4. Modular goalie arm (sub 30 lb, replace shooter at competition)


  • 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
