Hello everybody!

my name is Antonino and I work as a teacher in a Secondary School in Spain and I want to teach to my students how to use ROS.

my students using ROS

I have a Turtlebot 3 burger and we use it without problem but now we are trying to do the same things with a Turtlebot 2 and we are having some problems.

The Turtlebot 2 has an Astra camera and I have no problem when we do this.

roslaunch astra_launch astra.launch

rosrun rviz rviz

But, when we try to create a map we get this error:

No matching device found.... waiting for devices. Reason: std::__cxx11::string astra_wrapper::AstraDriver::resolveDeviceURI(const string&) @ /tmp/binarydeb/ros-kinetic-astra-camera-0.2.2/src/astra_driver.cpp @ 741 : Invalid device number 1, there are 0 devices connected.
[ INFO] [1557657651.767909049]: Using plugin "static_layer"

Reason: std::__cxx11::string astra_wrapper::AstraDriver::resolveDeviceURI(const string&) @ /tmp/binarydeb/ros-kinetic-astra-camera-0.2.2/src/astra_driver.cpp @ 741 : Invalid device number 1, there are 0 devices connected.

I execute this commands:

roslaunch turtlebot_bringup minimal.launch

roslaunch turtlebot_navigation gmapping_demo.launch

We have added export TURTLEBOT_3D_SENSOR=astra in the .bashrc file.

Could you help me?

Thank you in advance!

Regards,

Antonino

Thank you very much for this forum. I have found the solution searching on it.

I have found it:

http://wiki.ros.org/rtabmap_ros/Tutor...

and now everything is working properly.

But I know we are going to need a lot of help, for this reason, if you want to participate in our project it would be fantastic.

We want to do a robot who can guide people inside our school. We are going to create the map and after that we will mark some places where the robot can guide you.

It would be fantastic to improve a conversational system but firstly the first.

Thank you again.

Regards
