Gesture Controlled Mobile Robotic Arm Using Accelerometer

In this paper we have presented a model to control robotic arm through human gestures using accelerometer. A three axis accelerometer is mounted on human hand in order to perform the action of robotic arm according to the action of human hand. Accelerometer is connected to the LPC2148 Microcontroller which is programmed to take analog readings from accelerometer and transmit them using Bluetooth to the receiving unit at robotic arm. Movements of the robotic arm are achieved through ServoMotor are a type of electromechanical actuators that do not rotate continuously like DC/AC or stepper motors; rather, they are used to position and hold some object.They are used where continuous rotation is not required so they are not used to drive wheels (unless a servo is modified). The arm is also equipped with a gripper to facilitate the pick and drop facility.The main aim is to control the robotic arm using human gestures wirelessly with smooth movement over a range.
