unable to move arm with moveit!

edit

On kinetic, Ubuntu 16.04, trying to make the arm of my robot move a little bit.

the code:

bool run_script(){
    moveit::planning_interface::MoveGroupInterface move_group("arm");
    geometry_msgs::Pose target_pose1;
    target_pose1.orientation.w = 1.0;
    target_pose1.position.x = 0.28;
    target_pose1.position.y = -0.7;
    target_pose1.position.z = 1.0;
    move_group.setPoseTarget(target_pose1);

    move_group.move();
    return true;
}

The log:

I even tried getting the current pose and change it a little:

bool run_script(){
    moveit::planning_interface::MoveGroupInterface move_group("arm");
    geometry_msgs::PoseStamped pose1 = move_group.getCurrentPose();
    pose1.pose.position.x = pose1.pose.position.x + pose1.pose.position.x/4;
    move_group.setPoseTarget(pose1);

    move_group.move();
    return true;
}

If you need anymore info let me know.
