# MR-B3RB History

## History

MR-B3RB is short for Mobile Robotics - Buggy3 Revision B. This is the second revision to a robotic vehicle called [MR-Buggy3 introduced in 2023](https://www.nxp.com/design/design-center/development-boards-and-designs/mobile-robotics-buggy3-kit-including-rddrone-fmuk66-and-peripherals:MR-BUGGY3). \
Some people didn't like calling a product "buggy". So even though Buggy3 is a brave name, we decided to instead make it MR-B3RB as it is a nice and friendly robot like R2D2. \

We took lessons learned from that platform and applied them as an upgrade for 2024.

The upgrades of the MR-B3RB are:

* Uses the same rugged metal base RC car,  with readily available replacement and upgrade parts
* No need to change the steering servo
* Upgraded BLDC motor with gear reduction, integrated ESC (motor controller) and quadrature encoder output that can be used for vehicle odometry
* Metal upper chassis that can be removed as a module
* Power distribution board with additional connector matching and power supply for boards and servos.
* Removeable mounting plate for companion computer, real time processors, communications radios and any other add on components
* RGB addressable lighting
* Optional upgrade to plastic sides, front, rear and lidar arch mount
* Optional GPS / remote Magnetometer/ arming button

Currently this is the PRE-Production version, there will still be some updates coming to improve the modularity of the top plate, and provide additional mounting for user added 3d printed components.
