Abstract:
Micro electromechanical systems (MEMS) (also written as microelectronic and micro electro mechanical systems) is 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 wheelchair using MEMS. The MEMS will be fixed to the hand. Whenever the hand moves in a particular direction, the mechanical movement of the hand will be recognized by MEMS. MEMS converts this mechanical hand movement into equivalent electrical signals (X, Y, Z coordinates) and send it to the microcontroller. The communication between microcontroller and MEMS takes place based on i2c protocol. In this protocol microcontroller acts as a master and MEMS acts as a Slave. The master receives the signals from slave and based on them it controls the wheel chair. Wireless Wheel chair has two D.C gear motors. These motors move in 2D direction with the help of driver IC L293D according its input signals. This driver acts as H-bridge. This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation.
