Hand Gesture Controlled Robotic Arm for Industrial Application

The recent days have seen robotics reach such a level that robots are being used in day to day tasks. Hence, real time controlling and automation is important to increase the human robot interaction levels. They are also shown to have a positive effect on human psychology. This paper revolves around the different steps included in building a robotic arm and the ways to control the robotic arm through gesture recognition. The robotic arm can be built by using various 3D printing technologies like PLD, FDL etc. This is done due to the presence of different gear mechanisms present in the design. The movements are achieved by using metal geared servo motors with high torque output. The robotic arm is simulated as a CAD model before it’s construction. The hardware subdivision includes the design and synthesis of a robotic arm whereas the software subdivision includes the control of the robotic arm through hand gesture recognition and also the different ways in which communication can be established. The result was a 4 DOF robotic arm which was controlled by hand gestures gained by different sensors and sent via wirelessly through communication established by a long-range module.
