2019-05-20 02:05:16 -0500 | marked best answer | error while launching robot model Hi all, I am trying to launch a robot model in gazebo(using ros indigo and ubuntu 14.04). But a node 'spawn_model' which is specified in launch file is automatically killed while running roslaunch and robot model is not yet launched in gazebo . My urdf file is fine and I checked it using gzsdf tool and by launching the model in Rviz. So I edited the launch file by adding respawn="true". So I am getting error "[ERROR] [1506783269.127628154, 11.257000000]: SpawnModel: Failure - model name hobo already exist.". What does this error mean? please help C:\fakepath\Screenshot from 2017-09-30 20:28:28.png launch file is : </launch> urdf file is : |
