Hi ROS community,
I would like to introduce our newest free ROS tutorial where you will learn how to use LIDAR and RGB-D camera of your robot in the same time to explore an unknown environment in order to find a predefined object based on a reference model. You can find it here: https://husarion.com/tutorials/ros-tutorials/9-object-search/ .
It is a first tutorial from a new series showing you how to use Robot Operating System to solve real life robotic problems. You can run that in Gazebo, ROS Development Studio by TheConstructSim, or ROSbot 2.0 platform.
I hope it will be useful for you and I would be grateful for your feedback 
.
Best,
Dominik
