Hello everyone,
We operate a BlueRov2 in the heavy configuration and sometimes have to use it in water with strong currents. For this we would like to have more powerful motors like the T500 for the forward drive. What do we have to change to operate the motors on our ROV?
Our Idea:
What else are we missing? Do someone has done this rework?
Hi @reallabor -
Welcome to the forums!
TheT500 is larger than the T200, so would not fit on the BlueROV2 without modifying (replacing) the side frame panels. Additionally, at 4S the system would be significantly more efficient, but not actually draw any additional power / provide additional thrust. Running with 6S is possible, but as noted on the T500 product page full throttle usage must be limited to less than 60 seconds to avoid heat damage to the thruster.
For strong currents, adding a 9th T200 thruster pointed along the forward axis of the vehicle can help significantly! I’ve used such a thruster to aide propulsion, although its primary purpose was collection of objects into a container (and subsequent ejection.)
Just how strong are the currents you’re trying to overcome? If going deep in strong currents, a clump weight attached to the tether is likely a better solution to the challenge…
Hi,
Thanks for your reply.
Yeah, the reworking is something which we had to do. We have Currents around 2.5-3 m/s.
Is there any possibility to calculate how much Thrust is needed at which current?
A simple Bernoulli equation (and assuming the BlueRov2 is a flat plane for easy calculation) would lead to the conclusion, that with the addition of a Forward Thrusting T500 it would be possible to overcome such currents. Could you provide some Ideas how to tackle this Problem.
