Mechanical Fabrication

  • Pivots
    • Tap 8-32 holes (sensor mounting) in pivot module bottom plate and 4-40 holes in the pivot module top plate
    • Start cutting down miter gears (that we have, including gears mined from old (pre-2013) pivots)
    • Weld pivot tubes to pivot tops
    • Complete wheel-sprocket assembly (bolts should be in)
    • Complete steering motor assembly and mounting (bolts should be in)
    • Cut & machine 7075 Al transfer axles
    • Cut and key 4140 steel co-axial drive shafts
    • Fabricate angle sensor mounts
    • Broach 12T sprockets (3/32" keyway)
  • Chassis
    • Cut (2) additional 25-3/4" 1x2" U-channel
    • Rough-cut gussets
    • Start milling 1x2" channels

Design

  • Layout basic state logic with programmers (Siri, Julie - draft done)
  • System-level ball routing, ball auto-ejection, manipulator tensioning

Programming / Control

  • All programming team members need to install LabVIEW and FRC software on a personal computer (see DEWBOT_X_Programming for details) -- Make sure FRC 2014 appears when starting LabVIEW
  • All programming team members need to complete the certification test
  • Preliminary list of programming products needs to be created
  • The programming team needs to organize into product sub-teams
  • Position and angular error spread for autonomous movement (by revolution counts) via testing procedure (Pat, Julie, Siri - procedure documented)
    • 3 trials baseline completed
    • Tweaks to try for additional baseline trials:
      • Wheel initialization -- rotate 360 degrees (no shortest distance), then back 180 degrees? (Need to confirm numbers)
      • Ramp up drive power based on revolutions reported by encoders
    • Gather tach-based autonomous driving trial data
  • Demonstrate move to/wait for Hot Goal
  • Demonstrate dashboard-to-robot-code communication
  • Prototype shooter code
  • Prototype ball collection code

Scouting

  • Layout preliminary match and pit UI sheets and Excel/Tableau files
  • Lock down prioritize (first generation) metrics

PR

  • Paint more hats
  • Plan/start videos (at least release video)
  • Vests and sweatshirts

Welding

  • Build a shelf storage unit for the welding area giving welding team much needed practice.
  • We've been using alloy 4043 for all our robot welding. However, alloy 5356 may be a better choice. It is more ductile and stronger especially in

shear, which it what many of our chassis joints are subject to. We need to devise a simple test to evaluate.

  • Weld pivot tubes to pivot tops
