We hope you are ready to embark on an exciting journey into the world of robotics.\
Meet MR-B3RB – your very own robot Buggy that you build from the ground up. Even though the the B3RB is toy sized, it represents a complete generic representation of a heterogeneous ROS2 enabled robotic platform with real time processors and model predictive real time control. \
\
This guide will walk you through the steps to prepare the hardware and the starter software. \
Please note this is an ADVANCED system, and a background in,  or desire to learn ROS2, Linux, and Real Time Operating Systems is a pre-requisite in order to be successful in further development on the platform.
