---------------------------------------------------------------------***--------------------------------------------------------------------Abstract - In recent years, robotics is a booming technology in the field of science. The purpose of our project is to provide a hand motion controlled robot which is easy to use and handle. The hand motion controlled robotic arm, which is mounted on a robotic car, can lift a required object from a safe distance. The accelerometer controls the movement of the car and the motion of the arm. The development of accelerometer based wireless robotic arm is based on wearable accelerometers. The accelerometer is a three axis accelerometer. Accelerometers are used to measure the angular displacement of human hand motion. When it is mounted on hand glove and linked with the ARM controller, the signal transmitted by the acceleration force is sent to the ARM controller which after processing it sends to the ZigBee transmitter module through UART. The claw of the arm is operated with flex sensors. Wireless communication is obtained by ZigBee modules which are linked by ARM controller on both transmitter and receiver.
Key Words: Accelerometer, ARM, ZigBee, Flex sensor
1.1 Literature Survey
1. Introduction Robotics is a new emerging technology in the field of science. Many universities across the world are trying hard to come up with new products in this field to help mankind. Robots can be controlled wirelessly or by using wired controller. In many of the fields robots have replaced humans but still they need to be controlled by them only. Earlier robot were controlled using physical devices but now a days they can be controlled using hand gestures. Hand gestures is the simplest and the natural way to control robots. Hand gesture controlled robots were developed in order to help mankind to they are reach places which are out of reach and hazardous to them. These robots have a transmitting side and a receiving side. The transmitter is mounted on the hand, while the receiver is mounted on the robot itself. The transmitter consists of accelerometer, flex sensor, ZigBee module and the ARM microcontroller and the receiver consists of Arm controller ,robotic arm ,motor driver ,a robotic car and ZigBee module. The accelerometer motion is used to control the robotic car while the flex sensors mounted on the fingers are used to control the claw of the Š 2017, IRJET
robotic arm. The values of the flex sensors and the accelerometer are given to the Arm controller which processes it and is sent to the ZigBee module for transmission . The receiver receives these signals wirelessly via the ZigBee module and then sent to ARM controller for processing through the UART. These processed signals from the controller are used to drive the robotic car and for controlling the robotic arm. Receiver is mounted on the robot itself. The transmitter prototype consists of accelerometer, flex sensor, ZigBee module and the ARM microcontroller and the receiver prototype consists of ARM controller, robotic arm ,motor driver ,a robotic car and ZigBee module. The accelerometer motion is used to control the robotic car while the flex sensors mounted on the fingers are used to control the claw of the robotic arm. The values of the flex sensors and the accelerometer are given to the ARM controller which processes it and then are sent to the ZigBee module for transmission. The receiver receives these signals wirelessly via the ZigBee module and then sent to ARM controller for processing through the UART. These processed signals from the controller are used to drive the robotic car and for controlling the robotic arm.

In the robotics field, several research efforts have been made to create user-friendly robots, implementing user interfaces such as colour touch screens, a 3D joystick. But, these techniques are not efficient to control the robot as they do not give accurate results and provide slow response time. In the past years the manufacturers of robot have made efforts for creating “Human Machine Interfacing Device� using gesture recognition concept. Various technologies like light based recognition, vision-based gesture recognition, finger gesture recognition and accelerometer based gesture recognition have been evolved for controlling the robots. Light-based Gesture Recognition: Controlling robots with light sensors is being implemented in many cases. The sensors send some rays of light and track them as they gets absorbed in the surface or reflected back to it [5]. According to this, the robot can be line-sensing robots where it is made to follow a black or a white path. Finger gesture recognition: It aims to make it feasible to interact with a portable device or a computer through the recognition of finger gestures. ISO 9001:2008 Certified Journal
