i find the velocity will oscillate and the amplitude will get bigger and bigger. i think it should be the issue of the PD parameters.
adding a velocity boundary of [-10,10] can fix this. just for your reference.

The urdf file is missing, so we cannot reproduce it.

If my question is unclear let me explain this again:

The 2 wheeled bot gets unstable after some time and then it flies away. What does this mean, is my model stable or not? because it is working well in the starting but afterwards it flies off.

Is this problem faced by anyone else as well? or is it just happening in this case only?

Thanks in Advance

Hi everyone,
While I was trying simulating self balancing bot using PD control but it blows away after some time I spent a good amount of time figuring out what's the issue but I couldn't figure it out.
