No joint solution found while trying to use inverse kinematics on Baxter robot

I am trying to move a the arm of a Baxter robot by inputting the position and orientation but so far neither of the two methods I tried (ik_service_client and baxter_pykdl ) worked. They gave the result that no IK solutions were found.

I started by setting the left arm of the Baxter robot at a position then I used the function endpoint_pose() to get the position and orientation of the arm. I used the values I got for the position and orientation in code but it gave me the result NO IK joint solution found . I also tried using the values on baxter_pykdl and still no joint solutions were found.

If any one knows how to fix the problem a their help will be greatly appreciated.

Did you try the with the standard values? Did that work? Also, do you have the standard IK solver (KDL) configured or something else?

@rbbg I am not sure what the standard values of the are, but I am assuming it is the values that were initially set for the position and orientation. If that is what you mean then I tried them and they worked fine.

@rbbg I followed the instructions here to install baxter_pykdl. I dont have the standard IK solver (KDL) .
