[ros-users] IK errors

[Manuel Rodríguez]

Hi all,

I'm using the Wizard<http://www.ros.org/wiki/arm_navigation/Tutorials/Automatically%20Generating%20Arm%20Navigation%20Configurations/Planning%20Description%20Configuration%20Wizard>to
create the IK packages for a modular arm. Problem is that when I try
to
use the IK functions, I obtain this messages:

*[ERROR] [1318490902.387172103, 293.778000000]: Incorrect number of elements
in IK output.*
or
*[ERROR] [1318491313.909772482, 1081.821000000]: IK Solution not found, IK
returned with error_code: -31*


Has anyone an idea about what happens?



Best regards,
manuel
