Notes

• New relay ahead of power distribution block for ESCs.

• Need to diagram the E-stop circuit

  • Include Hall Effect E-stop board

• Concerns about Presto being chonky

  • But this is only needed for software E-stop

• Servo folded motor

• Camera under ROV? or camera pointed down?

  • Aaron would rather have DVL than camera
    • (underwater GPS)

• Detachable tether

  • CDR forthcoming

• Second tube

  • Jetson
  • Pico
  • Presto

• Nick’s idea

  • BlueROV tethered to boat
  • BlueROV has antenna
  • USV does the rest of the stuff

• Challenges

  • Detachable tether → ROV to boat makes life less good
  • Fully tethered can get caught

• GPS on BlueROV

• Takeaways

  • Shrink / modify Presto, E-stop boards
    • Add parts to bill
    • Design review PCBs
  • Add relay to bill
  • Add tube to bill
  • Figure out power distribution system for non-estopped hardware
  • Sketch out E-stop circuit
  • Non-thinking sub is priority for RobotX
    • Thinking sub maybe for Sub
  • Add GPS antenna, Heltec antenna connectors, R/C antenna

  • Waterproof servos
  • Light indicators (already in lab)
