Abstract:
There are several ways of navigation of a robot. Some of the ways of navigation of the robot is by using IR sensors and line following robot in which the robot follows a predefined path. There are disadvantages of the previous methods of navigation. Localization for autonomous mobile robots is the process of determining and tracking the position and the orientation (i.e., the pose) of the robots in any given environment. Localization is a fundamental technique that allows robots to navigate, explore, or perform their intended tasks successfully without human intervention. The topic of localization has received considerable attention over the past few decades.
Existing System:
In the existing system of navigation of robot several methods are used. Some of them are using IR sensors in which IR transmitter and a Receiver are used. Another method of navigating is by using a line follower mechanism. In which the robot follows a specific predefined path.
Proposed System: In the proposed system instead of using IR and line following robots. Ultrasonic sensors are used to help the robot in navigation. The system consists of ultrasonic sensors that are used to identify obstacles and walls in a room. The robot operates using a microcontroller. The robot is attached with a pick and place mechanism that makes the robot used in several applications. The robot is controlled through Zigbee using a PC.
