May 4, 2016 at 6:41 comment added James potter the axis is pointing in the wrong direction..
May 3, 2016 at 22:19 comment added James potter So.. I think basically my issue has been that the distance i wanted to travel was too large, and singularities.. So i tried to fix them.. but things still doesn't seem right..
May 2, 2016 at 20:57 comment added James potter Moving it to a position with less singularity computes reasonable Q's.. but the trajectory isn't spheric as hoped. ... I think i might be because of the start configuration, and the large displacement it has to make to reach the goal.
May 2, 2016 at 17:47 comment added James potter hmm... It seems pretty hard to find a start configuration which jacobian doesn't entail in to a singularity...?
May 2, 2016 at 17:19 comment added James potter The determinant were computed to Determinant: 2.67004e-40... Probably a singularity...
May 2, 2016 at 16:52 comment added James potter I am not sure how I should compute the difference between rotation vector as a 3 numeric values?... Taking the difference between the two 3d vectors would result in one vector, and not a numeric number describing the rotation from the current state to the desired state.
May 2, 2016 at 16:52 comment added James potter Thanks for the feedback. I have been debugging it myself a bit, (After a bit of a break) and found the error with the transform you mention in 1) and dq in3). The library itself is pretty tricky to install, and might tends to be troublesome, I realize in retrospect that a install guide would be have been ideal here.. But yeah. I didn't think anyone would try to run it.. Thanks for trying :). I have been debugging the math (visulizing vectors and such stuff) for the sphere and transform function, and they seem to be correct. I think my error must be due to the way I compute du (...)
