Design and Implementation of an Articulated Robotic Arm for Precise Positioning
This project is intended to design an articulated robotic arm which could locate a point in space with its given coordinates at three degrees of freedom. The basic three rotary movements are base rotation, first and second arm swivel. With different payload capability and design, the robot can be employed in various industrial applications including spot welding, assembling, cutting, material handling and many more. The mechanical structure is designed and a physical setup is developed for which a microcontroller based control circuit is designed for the purpose of control. This paper is focused mainly on the mechanical design of the structure. An elaborate analytic description of the components and tools is presented with necessary specifications. This structure is very flexible and has the ability to reach over obstructions. It can achieve different positions and orientations with in the working envelop.
