Work Completed

  • Earlier in the day, Adam updated the Limelights, fancy new update that will determine distance (both x & y & angle) from target, super useful to align autonomously
  • Set up basic Hatch code commands
  • Billy explained PIDs and calc
  • Tested new ultrasonic sensor on Atla-Z, it works :)
    • Need to figure out best way to wire them bc the soldering looked sketch
  • Light sensors
    • Sam & Bryn soldered them all
    • Tested long strip on arduino with Billy, wiring every other sensor... it worked well

Challenges

Shaky hands

Code is hard

Light Sensors need to be calibrated every time the robot is turned on...

Cad (or Chris) need to figure out mounting for ultrasonics and more importantly light sesnors

 

Work for Next Meeting

  1. Wire DT1 & DT2 as the rest of the robot gets assembled

    • We still need to add the radio, ethernet switch, solenoid block, arduino, limelight, ultrasonic sensors, talon SRXs, victor SPXs, encoders, potentiometers, light sensors, and some more that I'm probably forgetting

  2. ROBOT CODE!!!!!
    • Get drive correction working
    • Hatch PID controller --> Vasista suggests no PID, just check where encoder is and stop accordingly
    • 1 step process for climber
    • Cargo set points
    • Vision
    • etc. etc.
  3. Install More Boards on comp & practice bot RoboRIOs. Manual for More Board:
    http://www.revrobotics.com/content/docs/REV-11-1100-UM.pdf
  4. Make list of all the general & subteam specific electrical components on the robot (FRC4096 --> 2018 - 2019 --> Build Season --> Electrical folder --> Electrical components)
  5. Continue the schematic for the electrical system using the schematic software stuff --> talk to Malia & Caden about this if you are interested (or maybe eddy)
  6. Get drivetrain code to work on the debugger (may just need to add the physics and sim files to the code???)
  7. Vision
    • Now that the gyro is working again, this should be worked on some more...
    • Drive robot towards vision target so the target is in view of limelight; then have robot drive to a specified distance and turn to a specified angle from the vision target (using a calibrated position and the tx & ty from the limelight)
    • Get Rotate_To_Angle_Limelight command working on Poly again.  PID will need tuning.
    • Continue learning how to use limelight
      • Specifically learn what all of the different values on the network table are and how they can be used
      • Continue to look into the Limelight documentations
    • Go to specified range from target (check case studies on limelight website & documentation)
    • Go to specified range and aim at target (again check case studies)

On Schedule?
