Abstract
Modern robots are designed to assist or replace the human beings in activities and
complex tasks of planning and control such as manipulating objects, helping specialists in
a multitude of jobs, navigating in outdoor settings, exploring unknown territories and
driving in urban areas.
Therefore, the aim of the thesis was to create a smart robot, which detects and follows a
visual line embedded on the floor. The path is predefined and can be visible on a white
surface with a high contrast color like a black line, or a more complex like laser guide
marker.
Various sensors can be used to detect these lines. Infrared sensors are generally used to
detect the line to be followed by the robot. The movement of the robot is automatic and
can be used for long distance applications. In fact, this robot have the ability to detect
obstacles. Usually if any object is placed on the path, a regular line follower will attempt to push the obstacle, what will damage it. However, this proposed robot can detect an obstacle,remove or avoid it using an ultrasonic sensor. This type of robots can performmany tasks in industries, such as material handling, as a support of automated equipment carriers in industries that replace traditional conveyor belts or can be used for domestic applications and health care management. Since this smart mobile robot has the ability to detect obstacles, it will not be easily damaged as it has the capability to avoid or eliminate obstacles, what gives it an additional advantage wherever it is used. In addition, this ability increases its application especially in industries because obstacles are common in any workplace. The main future challenge within a navigation process is that the environmental conditions are difficult to control, because the mobile robot executes its tasks in dynamic environments. The additional
challenges of scaling this small robot up to useful industrial capabilities were also explored
