URDF crazy update
After load the URDF, the model keeps updating the state in a crazy way.
Here is my launch file. Can anyone explain why ?
<launch>
<param name="robot_description" textfile="$(find fetch_robot_des)/urdf/fetch.urdf" />
<include file="$(find gazebo_ros)/launch/empty_world.launch">
</include>
<node name="spawn_urdf" pkg="gazebo_ros" type="spawn_model" args="-param robot_description -urdf -z 1 -model fetch_model" />
</launch>
Without knowing what "crazy way" means, this will be a guess, but: you don't have any active controllers?
I do not add any joint state controller. Theoretically, the robot joint state should not be updated. However, once I start the launch file and the robot starts keeping updating the robot state, like dancing until it falls.
