Yes, may be. > Are we > misunderstanding eachother maybe?

I need to put somehow 3 short values (torques -- to tell 3 motors how much to spin around) into the kernel space via ff layer. I computed them using FP in US from forces (3d vector) and the problem is, that I don't know how to transform torques to plane(s) and dir and then back to torques -- this is what I can't figure out, since I have no longer vector -- 3 values for each axis, which says how big is the force in each axis -- but I have values (no axis) specific to each motor. thanks for notes, -- http://www.fi.muni.cz/~xslaby/ Jiri Slaby faculty of informatics, masaryk university, brno, cz e-mail: jirislaby gmail com, gpg pubkey fingerprint: B674 9967 0407 CE62 ACC8 22A0 32CC 55C3 39D4 7A7E
