So, what I found out until now, that for some reasons in
//pack spd, acc, jrk
no values are stored. However, pose works. So the error message is shown
because I want to access non existing data.
I can print all data in the for-loops and spd[i], acc[i[, and jrk[i]
contain values. I also can access them after storing it in Control2Arm.
They just don't survive serialization and parsing.
