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.
Specification

Motor and motor control
This part includes some I/O pins of one of the Nano controllers which could be put into the GMR.
The users can use them to connect the encoder and two kinds of motor controllers, D10 and D9 with
a GND pin can be used for Saber tooth motor controller another 6pins together D9 D10 D8 with VCC
and GND used for DC Motor Driver 2×15A - Lite D2 –D6 are used for the encoders.
Nano slots
There are 2 Nano slots on the GMR. For general mobile robot, this two micro controllers can help
you to solve the motor control and driver some special sensors. And they all have connected with
the main micro controller Mega ADK or Mega 2560. The communication way is the I2C.
Mega ADK/2560
The main controller of this GMR board. Because of the high performance of the Arduino Mega
ADK/2560. For the GMR, 8 I/O and 8 analog pins can be used. 3 groups of I2C pins can
communicated with other controllers and 2 groups of RS485 belongs to another nano controller
