Hi All,
I'm building a 5DOF manipulator and haven't had much luck building an IK solver. My urdf for just the manipulator and bash script (to convert to collada, trim to 5 decimals, etc) can be found here: https://github.com/babakc/moveo. The bash script is in the urdf folder. I've stripped out any links/joints that aren't part of the manipulator to simplify things.
I've tried setting a number of different orientations for the joints (so the arm isn't fully stretched out), but continue to get the same error when using the `--iktests` flag:
openravepy.databases.inversekinematics: testik, success rate: 0.000000, wrong solutions: 0.250000, no solutions: 0.750000, missing solution: 0.000000
Traceback (most recent call last):
File "/usr/local/bin/openrave.py", line 126, in
database.run(args=args)
File "/usr/local/lib/python2.7/dist-packages/openravepy/_openravepy_0_9/databases/inversekinematics.py", line 1128, in run

openravepy._openravepy_0_9.databases.inversekinematics.InverseKinematicsError: Inverse Kinematics Error
wrong rate 0.250000 > 0!
Any idea what i'm doing wrong here? I built openrave from commit 9350ebc... Not sure if that's the latest working one (latest commit from master failed to build).
Appreciate any ideas at all, as I've been bashing my head for days trying to get this to work!
Thanks.
