ROS Stage Indigo Turtlebot

edit

After install https://github.com/turtlebot/turtlebo... rosdep install --from-paths src --ignore-src --rosdistro indigo -y -rw i launch it roslaunch turtlebot_stage turtlebot_in_stage.launch

and now i see (in RVIZ) the map changing the hight (oscillating in z)

how to stop it?
