Should I change the PID parameters?

Hi, guys! I have a question now! I want to make a rov whose frame is the same as bluerov, but it is bigger and heavier. Can I use the stablize mode or depth hold mode directly? Should I change the pid parameters?
Thank you!

Hi,

If you want to have a better performance you need to tune the PID parameter. Any structural or actuation modification will need PID tuning to allow max performance.

That sounds cool!

Can I use the stablize mode or depth hold mode directly?

Yes, this should work the same as the bluerov 2 if your motors are in the same arrangement. A pressure sensor like the Bar30 will be required for depth hold.

Should I change the pid parameters?

Yes and no. Yes for max performance like @patrick mentioned, no, because performance will probably be pretty good in the first place with the same gains. Play with them until you are satisfied.

OK! Thank you, Jacob! I will have a try.
