Work Completed

  • Cut a 11.5in by 18in piece of perforated plastic board after looking at the CAD for the main electrical components of the robot to mount on
  • Mounted the Roborio, Power Distribution Panel, Voltage Regulator Module, Pneumatic Control Module, and the 6 Drivetrain Victor SPs to the the board using zipties
  • Labeled the motor controllers for the drivetrain on the control board that we have begun

Challenges

  • Figuring out the best layout

Work for Next Meeting

  1. Verify Roborio (gyro, actually) will be close to center of rotation on robot. Rearrange layout accordingly.
  2. Make list of all the general & subteam specific electrical components on the robot (FRC4096 --> 2018 - 2019 --> Build Season --> Electrical folder --> Electrical components)
  3. Continue wiring the DT1 once it is done being assembled by mechanical (should be sometime this coming week)
  4. Begin a schematic for the electrical system using the schematic software stuff
  5. Figure out the pneumatics situation
    • How many pistons?
    • Which pistons can be run together off of one solenoid?
    • How many double solenoids will we need then? ... if more than five, we will need another block ... if more than four we need another PCM on the robot
    • Will our compressor be strong enough to handle this all?
  6. Get drivetrain code to work on the debugger (may just need to add the physics and sim files to the code???)
  7. Poly Work...
    • Attach limelight #2 to poly again (on the front)
    • See 5. vision for details below
  8. Build a set-up to run a motor when testing and making prototypes
    • Adam bought a 4-AA battery holder with on/off switch. Hook this up and try using it to supply the +5v power to the new motor tester
  9. 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 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?

We were supposed to have the DT1 completely functional by tomorrow. Since it is not mechanically done, the entire team is behind schedule but not the electrical team in specific.
