What are mobile robots?

Mobile robots have the capability to move around in their environment usually this type of robots are programmed according to the needs of the programmer. This type of robots can collect information from the environment by using sensors, which is attached to the robot. There can be more than one sensors to collects the information and a circuit which processes the information. This processed information is either stored or send to the programmer. These types of robots are used in research work like land research work, industries, defense, etc. Sometimes this robots are also found the doing household works. The main problem with the mobile robot is that it cannot work automatically without human interaction. Autonomous robots are the robots that can perform desired tasks in unstructured environments without human interaction. A highly autonomous robot is mainly desirable in fields such as space exploration, cleaning floors and mowing lawns. Some modern factory robots are highly autonomous to the environment. Robot Sensors are essential components in making autonomous robots, as they are the only way for a robot to detect information about itself from its environment. There are wide varieties of sensors available like distance sensor, light sensor, sound sensor, temperature sensor.
