Hand Gesture to Control a Low Cost 3-D Printed Arm using Android Application

Abstract

In this era, the technology on computer usage is highly increasing and demanding especially in engineering, business and communication sector. Many applications are built based on a smartphone technology. The idea of this paper is to develop a hand gesture system based on Android application in order to control the 3-D printed arm. A MIT application invertor was used in developing an algorithm of the hand gesture controller. The app inventor can be used and accessed with accelerometer sensor that already built-in the smartphone via a Bluetooth connection. The Android applications was used as a communication tool between the Arduino Uno and the 3-D printed arm. The accelerometer sensor was acted as an input signal to control the hand gesture of the 3-D printed arm by the change or tilt of smartphones position. The output of this system is a servo motor that was mounted on the arm and used to drive the fingers. In this project, there system was classified by two; hardware part that consists of 3D-printed arm, Arduino, electrical component, and smartphone, meanwhile, the software part consists of MIT application inverter. The result shows the 3-D printed arm was able to be implemented with the wireless and Android application.
