I am trying to follow the tutorial at http://gazebosim.org/tutorials?tut=build_robot&cat=build_robot and in its third part http://gazebosim.org/tutorials/?tut=add_laser

I added the laser. However the laser appeared at the bottom of the robot instead of the top. This makes robot stand on the laser. Visually laser is in the air with some space and robot is on the top of it. Clicking robot shows that there is 4 links (chasis, left wheel, right wheel and link). Its calling hokuyo as link and the pose is (-0.000002, 0, 0.000005,0,0,0). hokuyo_joint is at position (0,0,0).

I am not sure what is messing it up or if tutorial is wrong. Any help will be appreciated.

I am using gazebo11.
