The aim of this project is to implement the robot direction control with MEMS through bluetooth communication. In this project we are controlling the direction of the robot by MEMS accelerometer. This accelerometer is placed at the human hand senses the movement of our hand either it is left or right or up or down and these signals are sent to the robot through bluetooth communication. The MEMS sensor is in built in the phone. When we tilt the phone in either horizontal or vertical orientation, phone sends proper commands which are then received by bluetooth module and passed to the controller. The microcontroller receives input and controls robot movements such as Forward, Reverse, Left, Right, Stop etc. through motor driver circuit.
Micro-electromechanical systems (MEMS) are free scale’s enabling technology for acceleration and pressure sensors. MEMS based sensor products provide an interface that can sense, process or control the surrounding environment. MEMS-based sensors is built up of very small electrical and mechanical components on a single chip. MEMS-based sensors are a crucial component in automotive electronics, medical equipment, hard disk drives, computer peripherals, wireless devices and smart portable electronics such as cell phones and PDAs.
MEMS technology provides the following advantages: cost-efficiency, low power, miniaturization, high performance, and integration. Functionality can be integrated on the same silicon or in the same package, which reduces the component count. This contributes to overall cost savings.
