If you want to move existing model within Gazebo simulation, you can do so via rosservice call.

Open a new terminal tab, and enter

rosservice call /gazebo/set_model_state '{model_state: { model_name: MODEL+NAME, pose: { position: { x: 0, y: 0 ,z: 0 }, orientation: {x: 0, y: 0, z: 0, w: 0 } }, twist: { linear: {x: 0.0 , y: 0 ,z: 0 } , angular: { x: 0.0 , y: 0 , z: 0.0 } } , reference_frame: world } }'

Special Note:

Some spaces in the above command CANNOT be deleted, if there is an error when using the above command, check you command syntax first.

E.g: Right: { x: 0, y: 0 ,z: 0 } Wrong: { x:0, y:0 ,z:0 } (missing space after :)

You can also experiment with this command to set robot arm's state, to make it into a certain orientation like this rrbot

rrbot_default

rosservice call /gazebo/set_model_state '{model_state: { model_name: rrbot, pose: { position: { x: 1, y: 1 ,z: 10 }, orientation: {x: 0, y: 0.491983115673, z: 0, w: 0.870604813099 } }, twist: { linear: {x: 0.0 , y: 0 ,z: 0 } , angular: { x: 0.0 , y: 0 , z: 0.0 } } , reference_frame: world } }'
