Work Completed

  • Adapted the code for drive correction to use encoders as opposed to the gyro
  • Tested the limit switch code and attempted to put a delay on the closing of the claws

Challenges

  • The limit switch is somehow both too sensitive and not sensitive enough
    • the closing of the lexan paddles sometimes triggers the switch
    • when the lexan switch plate is pressed on the outside, it doesnt trigger the switch
  • Driving straight is still not perfect, but it is better.

Work for Next Meeting

  • Create an auto that rotates towards the target multiple times
  • Add a small timer to the limit switch that will make it so that it is only considered triggered if it is pressed for at least a tenth of a second.
  • Continue testing/iteration on gear mechanism
  • pi
    • get the grip pipeline to run alongside the new python mpjg stream without incident
    • get networktables controlled exposure toggle
    • put new streams on smartdashboard
    • add support for 2 cameras
  • start auto behavior
    • 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 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
    • ​
