IoT Based Teach-Play Mode for Robo Arm

Industry 4.0 is a name for the current trend of automation and data exchange in manufacturing technologies. It includes cyber-physical systems, internet of things, cloud computing and cognitive computing. Industry 4.0 is commonly referred to as the fourth industrial revolution. Industry 4.0 refers to a new phase in the Industrial Revolution that focuses heavily on interconnectivity, automation, machine learning, and real-time data. This Paper presents a Robo Arm, which perform various tasks according to industrial requirements using industry 4.0. Some significant task such as industrial automation, painting, welding, package loading and unloading, cutting and application specific tasks can be performed using this arm. There are two sections in this paper, one is wireless section and another one is control section. Wireless section consists of WIFI module and two channel relays for switch action. Control section consists of microcontroller and servomotors. The controlling of robo arm can be done in two modes. Teach mode (mapping): Teaching a robo arm can be done using blynk web server. And it maps analog input for every 25ms in microcontroller. By pressing the button, it stores each servo position in a array. Play mode (mapping retrieve). It switches to play mode. When the play button is double tapped. Now the mapped data is retrieved and reads the array step by step and moves the robot arm according to the given input. This idea can be extended in a bigger industrial robo arm, which can handle large number of application.
