Mechanical Prototyping

• Prototype slingshot to determine accuracy of shot positions, including by pipe (pullback) adjustment
• Prototype roller frame for required rise (without or with forks)
• Prototype JVN catapult to determine accuracy of shot positions and how to load

Mechanical Fabrication

• Pivots
• Field pieces
• Shop organization tools

Design

• Stack-style chassis CAD for early plywood cut (Molly)
• Stack-style chassis tradeoffs (Ben, Gary, Siri, Clem, Molly, Kira)
• 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

• Complete machinist's shelf unit.
• 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.
• Prepare the welding table for use, including grinding off lumps and bumps, and checking for flatness.
• Make some specialty clamps suitable for chassis clamping and holding. Drill holes in table top to accept those clamps.
