We are a university team from China. We currently want to make a ROV using the same pixhawk2.4.8 + raspberry Pi 3 Model B solution as BlueROV and using the same firmware as BlueROV. Because currently affected by the new pneumonia epidemic in China, we cannot order some parts from the Internet for experiments, so we still have the following questions about this solution:
-
The ROV we make works under 50 cm (ie 1.64 feet) underwater. The working place is located in the open outdoors, and the GPS signal is very good. Can we install Pixhawk with the M8N GPS module of the type used on the drone, and then use a pole to stand the GPS module above the water surface so that the ROV can obtain accurate positioning?
-
If GPS is placed on the water surface so that we can obtain accurate positioning, does BlueROV’s existing firmware support this positioning information for navigation?
For example, to make BlueROV like a drone, first plan the route at the ground station, then upload it to pixhawk, throw the ROV into the water, then unlock the ROV, switch the flight mode to the AUTO position, and the ROV will automatically follow the planned route March. Is this idea feasible?

Can I use BlueROV as an AUV?
We will remake the structure of the robot that meets our actual use requirements, but the arrangement of the thrusters will not change, so theoretically we can transplant the BlueROV operation control system. We add a wireless data radio station (which is used on drones) to this system and place the GPS on the surface, so we want to know if the firmware currently used by BlueROV supports our editing tasks in the QGC software, and then pass the data Pass the radio to upload tasks to pixhawk, and throw the robot with no wire connection into the water to let him complete the work automatically. And return to the collection point. -
About we want to make a low cost AUV.
We want to make a cheap AUV based on the buoyancy adjustment system used on the T200 and submarine models, because the existing torpedo-like AUVs cannot be afforded by us. In China, such AUV products often cost as much as a few dollars. Million RMB.I have seen information about cheap AUVs on the website. Are there any related projects or case recommendations?
I came to the forum for the first time, and please include if there is something wrong, thank you all.
