Clarification on Task 1.4 (Piloting ROV into docking station)

Post by peyton_lee » Sun Jan 09, 2022 8:19 pm

Hello! I had a couple questions about Task 1.4, specifically for the additional challenge for the World Championship.

1. How long does the LED need to stay lit to be considered successfully docked (in the case where the switch comes loose or the button is disturbed)?
2. What waterproofing is recommended for the exposed terminals of the reed switch?
3. Will building instructions be provided for the surface station LED display?

Thank you!

Hi Peyton:

If the LED does not need to stay on for companies to get points. If your ROV pushes the button and the LED comes on for even a short time, you are good. At that point your product demonstration run is finished, and you have moved into your demobilization time period.

Yes, waterproofing of the magnetic reed switch is recommended. We used these same magnets / magnetic reed switches in the 2017 SCOUT class competition. The magnet is waterproof. In 2017, we just used hot glue over the wires going into the magnetic reed switch and they worked without issue.

The topside will consist of a 9-volt battery (with 9-volt battery cap) and 2 LEDs embedded in epoxy (from the 2021 Seabin task). I will work on building instructions for this and get them posted.

Good luck.
