Design and Implementation of Electronic Gesture Recognition Unit Using Accelerometer to Control Robotic Arm Powered With Cortex-M3 Core

–Mechatronics is one of the promising trends in the era of computing in today’s system automation industry and control. The proposed project is one such attempt of designing an accelerometer based system to communicate with an industrial robotic arm wirelessly. This project comprises of design and implementation of the robotic arm powered with Cortex–M3 based LPC1768 core. The core has to be interfaced with DC motors of robotic arm to control the movements of robotic arm. ADXL335 is a three dimensional accelerometer sensor used for this purpose, this accelerometer sensor captures gestures of human-arm and produces three analog output voltages in three dimensional axes. And two flex sensors are used to control the gripper movement. For different movements of accelerometer and flex sensors corresponding characters will be sent to the Cortex-M3 core wirelessly using 2.4GHz RF module. And depending on the received character robotic arm can be controlled in Dynamic or Static mode by communicating with EEPROM using I2C protocol.
