A router is like a traffic cop for information on the Internet. Imagine the Internet as a vast network of roads. Your router is like a smart traffic signal that helps direct data (information) between your devices (like computers, phones, or tablets) and the rest of the Internet. It ensures that data from your devices gets to the right destination and that the responses from the Internet find their way back to the correct device. In simpler terms, a router helps your devices communicate with the wider world of the Internet.
In the context of a robot, a router serves a similar purpose as in a home network but within the confines of the robot's internal communication system. The router inside a robot helps different devices within the robot (like sensors, processors, or other components) to exchange information and communicate with each other.
Think of the robot as a mini-network, and the router inside it manages the flow of data among the various components. It ensures that data generated by one part of the robot can be efficiently sent to another part that needs it. This internal router helps coordinate the activities of the robot by facilitating communication between its different "devices" or components, much like how a router in a home network manages communication between various devices like computers, smartphones, and tablets.
