"4 DOF Multipurpose Robotic ARM"

Robotic Arms have been used by industries to perform complicated and tedious jobs ever since its introduction in 1962. From assembly lines to paint shops these robotic arms are used extensively in Automotive Manufacturing Industries. Recently with the advancement of technology and advent of Internet of Things(IoT), Robotic arms have also started to plunge in the Medical Applications allowing doctors to perform surgeries remotely by controlling the robotic arm wirelessly. In this project we will build an IoT based Wireless Robotic Arm using Node MCU.
The working of the project is so simple, we control the Robotic Arm’s using four servo motor from an application using the internet. The NodeMCU has an inbuilt wifi module, so that we can connect the Node MCU to the internet. Next using the Blynk application in the mobile we have created an application to send values via internet to control the PWM values for the four-servo motor that are connected with the Node MCU. The arm can perform Pick & Place operations
