Abstract

The study and application of robotics are evolving rapidly, and the articulated robotic arm is a fundamental element of the study. This paper focuses on the design, development and control of a web application 3RP articulated robotic arm. This project aims to bridge the theoretical knowledge of robotics gained through classroom teaching with practical, hands-on experience. This enables students to understand some robotic concepts like degree of freedom, forward kinematics and inverse kinematics. The 3D design is done on Fusion 360. The 3D-designed parts are saved in stereolithography (STL) file format. These parts are then 3D-printed. The microcontroller implements kinematics calculations to give controls to the stepper and server motors. The web application is hosted locally on the microcontroller (Arduino + ESP 8266), and the board has Wi-Fi and hotspot enabled. As a result, users can connect to the hotspot generated by the microcontroller to access the web application hosted on it. The web application controls the robotic arm through the sending of commands, which are in the form of codes, to the microcontroller. The product design was tested and verified as being functional. The designed web application works well with the robotic arm and the arm was able to carry a load of 1.5 kg.
