Practising SLAM and navigation with the GoPiGo3

Like it was mentioned at the end of the previous section, we are going to run an end-to-end example of SLAM and navigation with GoPiGo3. The first process deals with building a map of the environment using SLAM. Let's retrace the steps listed in the preceding section and see how to execute each of them in ROS.

Exploring the environment to build a map using SLAM

Let's follow these steps to build the map of a simple Gazebo world called stage_2.world:

1. Launch the robot model within a modeled environment by running the following line of code:

T1 $ roslaunch virtual_slam gopigo3_world.launch world:=stage_2.world

This command launches Gazebo and places the GoPiGo3 model...
