Abstract
The aim of our project was to design and fabricate a Robotic Arm for picking and placing objects from one place to another in other words for “Pick and Place Application” which can help people in their daily use and industrial applications. Basically, the design of Robotic arm was inspired from the human arm. We used the combined knowledge of Mechanical, Electrical and computer science. Four servo motors were used in this robotic arm. Each motor served the purpose for the movements of the elbow, shoulder and gripper joints. Each servo motor took the voltage of +5V and 600mA current. Thirteen ball bearings were used for the movement of links in upward, downward, forward and backward motion and for the motion of robotic arm’s base in 180° rotation. An android mobile app “Multiple servo control” was used for the real-time programming and controlling of all the servo motors of this Robotic arm. The app was connected wirelessly through an “HC-05 Bluetooth module”. An Arduino Nano ATmega328 microcontroller was connected to the circuit which was used to program all four servo motors in the android mobile app. Four Buck converters were used for each servos whose main purpose was to convert main AC supply voltage of +12V to DC supply voltage of +12V which then helped in stepping down that +12V DC voltage to +5V DC voltage for each servo. Now-a-days, robots can cause joblessness by substituting human workers but robots also create jobs for engineers, programmers, supervisors or as a robot technician. In the age of industrial revolution the uses of this kind of technology is increasing gradually.
