Work Completed

  • Created commands to quickly toggle the gear claws and the gear pegs independently of each other
    • This was used for testing of gear feeding
  • Looked at code we had not seen for a week
  • Helped with testing of gear feeding/shooting out

Challenges

  • Robot smelled like it was burning at one point
  • Gear feeder has a couple of issues you can find in the mechanical notes
    • JK mechanical doesnt do notes
    • The gear gets caught too far forward or too far back
      • It is either not perfectly in the mold
      • Or it is stuck on the push pegs

Work for Next Meeting

  • Make (more) sure the code works
    • In simulator, everything works except for the gear pneumatics which I could not test
      • The simulator cannot handle 2 Pneumatic Control Modules.  Code is fixed but no pyfrc release for it yet.
    • Make sure all pneumatic constants are correct
  • Continue work on moving to the peg
    • See how well it works if we have to drive then turn 30 degrees in the case that we do not get the middle starting position.
  • Work on auto mode that follows path, similar to one we'd need to get to a peg, test and see how consistently it can be navigated
  • Auto strafing based on position values from camera and network tables
  • Get streaming working well on raspi
    • Probably use custom python http server in vision_helper script
    • example http://answers.opencv.org/question/61070/streaming-http-server-from-inside-opencv2-python-script/
  • Get exposure control on driverstations (Needs Work)
    • works on linux, not windows
  • Try and connect to the frisbee bot

List from Mike (preventative measures):

  • Batteries
    • Battery Beak, logging and tracking internal resistance
      • Make a google spreadsheet to track battery data
      • Use computer to collect data/make a graph about voltage over time
    • Put meaningful labels on the batteries
    • Build load testing board
      • Resistors!
  • Power Distribution Panel
    • ​Can read voltage/current on every port
      • Could be used for diagnostics
  • Make a checklist
    • Learn how to read LED indicators on all components
    • Guidlines for checking wire integrity
    • Unit tests in robot code
      • Check to see if sensors are working?
      • Motors running correctly
      • Battery has enough voltage
      • Check the pneumatic pressure as well as solenoids
    • Useful for prematch/prebagging​
    • Voltimeter between the various locations
  • Sensors
    • Range finders - analog IO -> RIO (code)
    • Touch sensor - digital IO -> RIO (code)
  • Checkout Code // Comptetion Code
