MEMS based Robot Controlling through Android mobile

Micro electro mechanical systems (MEMS) are the technology of very small mechanical devices driven by electricity and it merges at the nano scale into nano electromechanical systems (NEMS) and nanotechnology.
The main aim of this project is to control the Robot using MEMS. Whenever the hand moves in any direction, the mechanical movement of the hand will be recognized by MEMS. MEMS converts this mechanical hand movement into equivalent electrical signals and the advantage if this project is we are using inbuilt MEMS sensor of Android phones
Android is a Linux based operating system designed primarily for mobile devices and it is a open source .There are so many applications are already developed on Android and many applications are being developed at free of cost for its users .
We can also develop our own customized applications with free of cost or with minimum cost according to our requirements.
In this project we will create an application to control the robot direction by moving your android phone in respective directions. According to phone movements our android phone sends a command to controlling section using Blue tooth.
At controlling system side, we have Bluetooth module, micro controller, robot motors driving circuit and Robot. Whenever this blue tooth module receives commands from android application, then it transfers this command to the micro controller. Micro controller will control the robot direction according to command it received
