 This GitHub&reg; repository contains MATLAB&reg; and Simulink&reg; examples for developing autonomous navigation software stacks for mobile robots and unmanned ground vehicles (UGV). The examples contained in this submission demonstrate how to interact with ROS-enabled robots and equivalent simulations to design and test a software stack for autonomous navigation of a Turtlebot3.
