[Explorer] Fuse in AC System

Hello, The competition manual specifies fuses that we must use in our 48v DC system, and we'll use one of those within 30cm of our DC power supply. In our control box, we want to essentially build our own power strip on a PCB to split the provided power input into 3 AC plugs, for the control box sys...

[Explorer] Cannon Bore minimum diameter?

The competition manual explains that the cannon bore can be a range of diameters, but we aren't given any constraints as to their possible size. We're exploring an idea where our ROV would insert an apparatus into the front of the bore, which would clamp outward and hold the cannon with friction. Wo...

Re: Is the bore of the cannon physically blocked?

I think they mean that, for the purpose of calculating the weight, you act as if the bore goes all the way through, but in reality, it's blocked.

[Explorer] International Competition Power Supply Specs

What power supply does MATE use at the international competitions? We are looking to buy a 48v 30a power supply to test with and we aren't having much luck. If possible, we'd like to replicate the setup at the competition as much as possible.

9V Battery in control station?

In our control station, we would like to use a relay to make our power switch more safe. Instead of having the power switch be part of a 48V circuit, we want to connect the switch to a separate circuit, powered by a 9V battery, which would be connected to the main 48V DC circuit by a relay. The powe...

Schrader Valve?

The competition manual states that "Battery containers utilize a pressure release valve AND a Schrader valve." for lift bag battery containers. Why is a schrader valve specified in addition to the actual pressure relief valve? What purpose is it supposed to serve?
