Abstract: The robotic arm is an electromechanical machine it is also called as robotic manipulator which is commonly used in industry. We had decided to design a robotic arm which works based on gesture of arm to obtain the similar operation as that of human arm. The gesture is captured by the flex sensor placed on the hand glove. The robot possess four degree of freedom with the help of dc servo motor. Thus the whole control is obtained by Arduino Nano microcontroller which will provide accurate control over the robot then joystick.

Keywords: Optical Flex Sensor, Arduino Nano atmega 328P Microcontroller, servo motor, wired.
