RE: RRA crash or runtime error

Hi Ayman, I got a question. Is there any method which would not allow RRA step to adjust the COM? Because I am experimenting some of my ideas about the affection of different COP related to the residual value for the moment.

Thanks for any help.

RE: RRA failed - Search direction becomes too sma

Hi Ayman,

Thanks for you reply. I see and I am still working on improving the GRF accuracy to make RRA work, another side, trying to decrease RRA ControlConstraints value to make them more like Gait2354.

Thanks.
