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
