RoboND-myrobot

The myrobot lab part of RoboND Gazebo Basics lesson. The purpose of this lab is to learn how to build a two-wheeled robot model with the Model Editor tool in Gazebo. Include this model in an empty Gazebo World. And, finally write a plugin to interact with this world.

Steps to launch the simulation

Step 1 Update and upgrade the Workspace image

$ sudo apt-get update
$ sudo apt-get upgrade -y

Step 2 Clone the lab folder in /home/workspace/

$ cd /home/workspace/
$ git clone https://github.com/udacity/RoboND-myrobot myrobot

Step 3 Compile the code

$ cd /home/workspace/myrobot/
$ mkdir build
$ cd build/
$ cmake ../
$ make

Step 4 Add the library path to the Gazebo plugin path

$ export GAZEBO_PLUGIN_PATH=${GAZEBO_PLUGIN_PATH}:/home/workspace/myrobot/build

Step 5 Run the Gazebo World file

$ cd /home/workspace/myrobot/world/
$ gazebo myworld

Output

The hello world message and the two-wheeled robot inside a Gazebo World should both launch as follow:
