I tried to change "move_arm_simple_pose_goal.cpp" http://www.ros.org/wiki/move_arm/Tuto...

I wanted to specify pos and orientation and changed desired_pose.pose.orientation.w = 1.0 -> 0.5 (line31)

Then there's error message

How can I fix it or change r_wrist_roll_joint's orientation?

You need to provide a proper quaternion. Just changing one value will obviously leave the quaternion unnormalized.

There are some convenience functions that create quaternions from roll,pitch,yaw depending on what you need.
