ABSTRACT
In the daily environments, robots encounter with humans, and they have to interact with them before doing the task. There are two main streams in the early robotics. One is navigation and the other is manipulation. Navigation is the main function of an autonomous mobile robot. It observes the environment with cameras and laser scanners and builds the environmental model. With the acquired environmental model, it makes plans to move from the starting point to the destination. This is the navigation, and it was the main issue not only for robotics but also for artificial intelligence. Rather, the interaction will be the main task of the robots. These robots developed by the companies had various functions with the animal-like or human-like appearance to interact with people. The robots developed by the companies will become part of the futuristic scene. The strongest reason is in the human innate ability to recognize humans and prefer human interaction.
