Re: Measuring voltage in water

A properly sealed motor should not do that. I talked with one of our lead safety inspectors and we concluded that this is likely a bad thruster - it did not get sealed properly. I would recommend talking to Rusti / Blue Robotics folks about this and getting a new thruster. Having a motor that is not...

Re: [RANGER] Changes to ROV after technical documentation submitted

You may continue to work and modify your ROV after submitting technical documentation. You should not add any major systems, or make major changes to a system on your vehicle after submitting technical documentation, but you may continue to make small improvements and additions. Note that anything y...

Re: Sponge in Cup for the grout task

That is not a sponge. It is Velcro stained with red food coloring that was in the agar (from 2017 missions ). The design of the task is very similar to the agar cup design of 2017. The Competition manual specifies how much grout you will need to insert into the cup. Good luck. Matthew Gardner MATE R...

Re: Micro-ROV

The Micro-ROV does not necessarily have to go through the hub of the main ROV. From the IMPORTANT FORUM RULINGS Companies may run their micro-ROV tether directly from the surface and through the ROV with no direct connection points. I.e. RANGER companies may use an extra set of conductors going down...

Re: Temperature Measurement

You may take a resistance reading. You should communicate with your station judge before taking this reading and let them know you are converting resistance to temperature, and how your are doing this (calculations / chart used ).

Good luck.

Re: [EXPLORER] Benthic Image Recognition

What MATE is trying to avoid is a team cheating by looking at the image (using eyes and brain to determine number of each species) and then hitting buttons that secretly have these numbers displayed on the screen. Before undertaking any hands on operations for the image recognition task, you should ...
