CMC problems with rower and 2 arms.

Post by Sietse Achterop » Fri Nov 29, 2024 2:56 am

Hello again!

Still trying to get my rower working with CMC. The previous version had only one arm and worked fine.
But after adding the second arm and consequently another kinematic loop it now fails again.

Code: Select all

Ipopt: Infeasible problem detected (status 2)
This exactly after 0.922 seconds.

Here the rower at 0.922 seconds, the moment it fails.

Notice both elbows are at 90 degrees. Something with a kind of gimbal lock in combination
with the other arm?
Or what else could be the problem, I am bit at a loss here.
Please find all data in the zip-file. Just try the CMC-tool to see it fail.

Thanks again, Sietse
