MEMS BASED HANDS GESTURE CONTROLLED ROBOT
Microelectromechanical systems (MEMS) (also written as micro-electro-mechanical, MicroElectroMechanical or microelectronic and microelectromechanical systems) is the technology of very small mechanical devices driven by electricity and it merges at the nano scale into nanoelectromechanical systems (NEMS) and nanotechnology.
MEMS are separate and distinct from the hypothetical vision of molecular nanotechnology or molecular electronics. MEMS are made up of components between 1 to 100 micrometres in size (i.e. 0.001 to 0.1 mm) and MEMS devices generally range in size from 20 micrometres (20 millionths of a meter) to a millimeter. They usually consist of a central unit that processes data, the microprocessor and several components that interact with the outside such as microsensors.
The main aim of this project is to control the Robot using MEMS. The MEMS will be fixed to the hand. Whenever the hand moves in any direction, the mechanical movement of the hand will be recognized by MEMS. MEMS convert this mechanical hand movement into equivalent electrical signals and send it to the microcontroller. The microcontroller at the transmitter side receives this and sends corresponding signals to the receiver side through RF TRANSEIVER OR ZIGBEE. The controller at the receiver side receives these signals and gives direction to the robot.
