不具合の概要

pick_and_place_two_arm_demo.pyを実行すると、bringupを起動したターミナルに次のエラーが表示されます。

[ WARN] [1647247236.339212746]: More than one constraint is set. If your move_group does not have multiple end effectors/arms, this is unusual. Are you using a move_group_interface and forgetting to call clearPoseTargets() or equivalent?

軌道生成に失敗しているため、サンプルを実行しても手先位置は変わりません。
