Efficient Movement of Robotic Arm to Enhance Object Handling and Sorting Operation

Vikas Gulia | Venkanna Mood

Abstract: In robotics, for accomplishing simple and complex tasks, manipulation is a very important aspect. Manipulation is achieved by different movement of the robotic arm. Here we are trying to design a Robotic Arm based on robotics arm concept to perform heavy task and lift weight using less power and efficient handling. In this we are implementing some technique to automatically sense the object and perform relevant task on it. Some of the input technique used in this paper are object sensing based on color and shape using sensors. Robotic arm movement is achieved using DC geared motors attached in different directions and angle. Each geared DC motor act as joint and helps in providing various movements to different directions. . Microprocessor controls the movement of the robotic arm by sensing the position and location of the object in the 3d space with the help of IR sensor and color sensor (object color detection, identification and interpretation). Knowing the location of the object we can then easily orient the arm to pick the object. The robotic arm picks the object and place it elsewhere in the vicinity of the arm. Thus, enabling the robotic arm capable of picking and placing the objects in the sequence based on the input and object sensed. The robotic arm is independent and can be integrated with other modules. We are using geared DC motor rather than servo motor to increase the angular rotation of the arm. DC motor are easy to interface and maintain as compared to servo motors. This whole setup consume less power and provide efficient working by using various modes.
