This document describes a gesture control robot project that uses an accelerometer. The aim of the project is to control the movements and directions of vehicles like airplanes, trains and cars using MEMS technology. The transmitter module uses an accelerometer, comparator, encoder and RF transmitter. The receiver module uses an RF receiver, decoder, microcontroller and actuator motor driver. The accelerometer provides analog data about movement in the X, Y and Z directions. The comparator and encoder convert the analog data for transmission. The RF modules transmit and receive the signals. The microcontroller processes the received data and the actuator converts it to control vehicle movements based on hand gestures detected by the accelerometer.
