In this video, we are going to explore the macros for URDF files, using XACRO files. At the end of this video, we will have the same model organized in different files, in a organized way.

In this 2nd video of the series, we are going to solve some compilation errors we got in the previous video, and we are trying to launch the nodes for performing LSD SLAM.
![[ROS Projects] – Build the Sentinel Robots from Matrix for Gazebo Simulator (Updating)](https://www.theconstruct.ai/wp-content/uploads/2018/02/Sentinel-The-Matrix-Octopus-Build-Part1-screen.png)
Learn how to build the Sentinel Robots from the Matrix for Gazebo Simulator. Learn about advances XACRO techniques. In these first set of videos you will build a basic geometric version.
Here is the git for the code: https://bitbucket.org/theconstructcore/sentinel
Second part where we talk about how the xacro works in depth.
The third video on the series where you learn how to build the sentinel of TheMatrix film, which is an octopus like robot. Learn how to build it in Gazebo and use ROS to move it around. Next set of videos will be about adding the meshes. Remember to post your crazy robot projects in this video and I’ll pick a winner on the next videos ;). Have fun with robotics.
In this fourth video, you will learn how to add meshes to the Sentinel-Octopus Model of The Matrix Revolutions that we did in previous videos for the Gazebo simulator. We will use as always ROS Development Studio for this but also Blender for the mesh import/scaling and Thingiverse for the download.
