send *ri* :angle-vector でロボットに姿勢を送った時にがたがたする人は、もう一度fetcheusのバージョンを調べてみて下さい.

$ rosversion fetcheus
1.0.7
$ rosversion pr2eus_moveit
0.3.6

となっているのが正解です、もうひとつ:angle-vectorを送った時に以下のような表示になるか調べてみて下さい.
チェックポイントはscaled trajectory total time というのが3.0以上になっている.例えば(send *ri* :angle-vector ... 5000) としたら5.0秒になっているはず.
最後の行がuse [arm]ではなく、use [arm_with_torso]になっている.

以上のチェックポイントが全てただしくて、まだがたがたしていたら教えて下さい.

あ、やっぱ、上の条件満たしていてもがたがたするかも.

hope 40f0963 and jsk-ros-pkg/jsk_pr2eus#255 works, this will send joint_trajectory without velocity and acceleration, if this not work, we'll calculate velocities.

Tested the changes and work it out! Normal movements, correct timing and correct use of torso.

Thank you very much

下記のようにgazebo内でfetchの腕を動かしましたが、目立ったガタつきはありませんでした。
