Gesture Actuated Robotic Arm

Abstract

The idea is to change the perception of remote control for actuating manually operated Robotic arm. This project presents a thought and a way to eradicate the bottons, joysticks and replace them with some other more intuitive techniques, that is, controlling the complete Robotic Arm by the operators hand moment or motion or gesture.In this project the completely electronics (without mechanical sensor) way of achiving the above stated goal is discussed. This is achieved by using MEMS-ACCELEROMETER and FLEX SENSOR technology(that is used in smart phones for tilt sensing), showing the diversity of the application of the same technology. It is basically an Accelerometer based system which controls a robotic arms wirelessly using a small and low-cost, 3-axis (DOF’s) accelerometer using Zigbee module. The accelerometer are mounted on the operator’s hand and according to the gestures postures of the operator hand the motors are provided with the appropriate voltage. This voltage is pre-tested and depending upon the voltage the motars of robotic arm will move to perform the work as operator is doing.
