Moving model out of origin gives error

I'm trying to move hector_quadrotor from origin to position `(-12.0, -1, 0)` in the world. The hector_quadrotor model is made of many parts. One of them, is the `sonar sensor`. My code to place it in the word follows: However, I got the error: propulsion model input contains **!?* Nan values! drag model input contains **!?* Nan values! The code to the sensor is this link https://github.com/tu-darmstadt-ros-pkg/hector_models/blob/groovy-devel/hector_sensors_description/urdf/sonar_sensor.urdf.xacro
