Introduction

This is a generic mobile robot control board. The GMR board supports up to 3 microcontrollers, two

Arduino Nano and one Arduino Mega or Mega ADK. One of Nano is used to control the motors and

their encoders, the other is used to drive 6 URM sensors. The Main microcontroller is the Mage or

Mega ADK, it is used to collect the date and work out the control logic. The GMR has two wireless

slots available which allow Xbee, blueteeth/Wifi to be used at the same time.

Note: The lastest version has been compatible with the newest Arduino Nano V3 & V4.
