Servo goes off with head rolling

[d130s]

At IN [3], all servo went off with "gacha" sound. This happens twice for me today.

ipython -i `rospack find hironx_ros_bridge`/scripts/hironx.py -- --host hiro

:

[hrpsys.py]  calib-joint all 
[hrpsys.py]  done

In [2]: robot.setTargetPoseRelative('head', 'HEAD_JOINT1', dp=0.45, tm=12)(array([ 0.    ,  0.    ,  0.5695]), (0.0, 0.45246578493159667, -0.018593892456891147))

setTargetPose failed. Maybe SequencePlayer failed to solve IK.
Currently, returning IK result error
(like the one in https://github.com/start-jsk/rtmros_hironx/issues/103) is not implemented. Patch is welcomed.

[k-okada]

humm, joint limit has changed due to new head parts?

[130s]

Some additional observation:

• In the command examples above, I didn't run goInitial. But there was another incident where I did run it, and the same error still occurred.
• From MoveIt!, I was able to move both of 2 head joints without any issue.
  • To do that with Hiro I needed a "hack" -- since in hironx_moveit_config package there's not yet head joints integrated, I used nextage_moveit_config just to move the head.
• I haven't confirmed whether the same issue happened or not with the default head model.

humm, joint limit has changed due to new head parts?

Hm, then I can't yet explain why the same issue doesn't occur with MoveIt!.

[130s]

I also wonder in the log why error limits were reported for arm joints but not for head.
