turtlebot gazebo problem frontal cliff sensor
Hello everybody! I'm new to ros and I've just installed the turtlebot package, but I have a problem: when I i launch the file I have :
Msg Connected to gazebo master 127.0.0.1:11345 Msg Publicized address: 192.168.1.131 Dbg Plugin model name: mobile_base loaded left cliff sensor <----I used a printf to debug

It seems to be a problem in loading the frontal cliff sensor. Any solution? I use ROS hydro on ubuntu 12.04 lts with gazebo 1.9.5
