What Sensors Are Used For Mobile Robots?
A mobile robot needs many types of sensors. Which and how many depends on the robot’s task and environment, and the sensor size, complexity and cost. Fortunately there are a variety of reasonably priced sensors that are effective and easy to use. A sensor’s effectiveness depends on its placement, synergy with other sensors, output processing, and interpretation. Sensors are used to either help the robot to move around or to accomplish some task besides mobility. Some sensors serve both purposes. We won’t attempt to be comprehensive but only refer to the most common sensors used. Refer to the book by H. R. Everett for more details.
