INTRODUCTION
GMR is the abbreviation of
General Mobile Robot controller. It's an integrated circuit board specifically
designed for home robot platforms, such as HCR
(Home Care Robot).
In this integrated version of GMR,
you will need three microncontrollers (MCUs): two Arduino Nano / Dream Nano and one Arduino Mega /Arduino
Mega ADK, wherein one Nano works as motor control and data acquisition, and the
other one as the ultrasonic sensor driver. The Arduino Mega /Mega ADK works as
the main controller board to collect and transimit data as well as to drive
other expansion modules, there is also a micro sd card slot for Mega ADK. There
are two extra wireless communication plots that can be plugged with Xbee,
Bluetooth and other communication modules. The GMR has intergrated 8 I/O ports,
8 analog ports and 3 I2C interfaces as input and output for Mega ADK. As for
the part for nano on the GMR, the board also has special ports for motor drive
and an adjustable knob for voltage output.
Note: The lastest version has been compatible with V3 & V4
