Can a robot hear your voice, even though it doesn't have ears? Today, we'll discover how robots hear the world around them. Instead of ears, robots use a microphone. A microphone is a device that captures sound waves. Sound waves are tiny vibrations that travel through the air when we speak. Just like your ears collect sound, a robot's microphone collects those vibrations. Next, the robot's controller processes the sound. It checks whether the sound matches a command it already knows. If you say "move forward," the robot recognizes those words and sends the command to its motors. The motors move the robot. The process is "listen, process, act." Here's the cool part. Some robots can recognize different voices and reduce background noise. This helps them understand people more clearly, even in busy places. Now you know that robots don't hear with ears. They use microphones to capture sound. Then they use programs to understand what the sound means and decide how to respond. That's how a robot can hear and follow voice commands. You've learned the basics of robot hearing. Follow to learn robotics from absolute beginner to advanced. Next lesson, how do robots talk?
