I am looking to design and build a wire-controlled, ESP32-powered underwater camera drone. I’m not decided on the exact form of depth control (using ballast tanks or just using the motors) yet, but in any case I want it to be able to rotate 360° on every axis.
Since I don’t want to risk water influx, I thought using flywheels would be an elegant solution. This decision poses the first set of (side-)questions:
- Do you think that would even work considering the density of water?
- How much delta-W do you think would be necessary to guarantee maneuverability (it’s fine if I have to take left rather than right turns sometimes to decrease RPM, but not being able to complete a single rotation would not be that useful)
Now, the main point of this question:
Provided you think the concept could even work, do you know of a ‘gyro-module’ (so a - preferrably 3-axes - integrated flywheel-module that can just be plugged into either a uC or an external motorcontroller?
I am asking this since experience has proven that trying to do absolutely everything yourself will end in disaster, and I’d rather put the effort into optimizing the robot itself instead of bothering with designing flywheels.
Thanks in advance for your - surely numerous - answers!
