Work Completed

  • We ordered new parts for pneumatics on the BOM (pneumatics has its own section)
  • Set up solenoids for both practice and competition bot this year
    • Found and then stripped and crimped wires for the solenoids (also had to solder/heat shrink)
    • Took a few from Poly which weren't being used for the drivetrain
  • Named batteries

 

Challenges

  • Nothing much, we lost track of one solenoid cable we unplugged but we still have enough. 

Work for Next Meeting

  1. Make list of all the general electrical components on the robot (FRC4096 --> 2018 - 2019 --> Build Season --> Electrical folder --> Electrical components)
  2. Build a set-up to run a motor when testing and making prototypes [ <-- hold off on this, we ordered a motor tester - Adam ]
    • Zach suggests using a three way switch (on forwards, off, on reverse)
    • One side, the motor is plugged in (two smaller anderson connectors)
    • A battery is plugged into the other side (large anderson connector on the battery)
  3. Drivetrain Code
    • Continue working on robot.py, const.py, and oi.py, commands/drivetrain.py & subsystems/drivetrain.py
    • Goal is to be done by early next week when the drivetrain is supposed to be done
  4. Vision
    • 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 Atlaz.  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)
  5. Line Following  (Ordered set of 3 line trackers from Vex, wait for those to arrive before resuming this work. -Adam)
    • Mount the color sensor to Atlaz. Needs to be only a few centimeters away from floor, pointed at the carpet.
    • Determine what sensor object to use in code to get values from it.  It's an I2C device.
    • Would be used to follow the white tape that is centered coming out from the spots where hatch panels are placed
    • Ultimate question is - Should line following be used instead of limelight vision in some places? Together with limelight vision? Or not at all this year?
  6. Talk to other subteams and drivers to determine what semi-autonomous controls are desired --> need list of everything we wish to accomplish and order of priorities --> this has been started, but more work is definitely needed
    • Will need to finalize these after designs are finalized but should start to get an idea now
    • Then figure out what the best ways are to implement them
    • Encoders? Gyros? Limit Switches? Vision? Line Following? etc. etc.
