Description: A node controller is an essential component in the architecture of distributed systems, especially in computer networks and robotics. Its main function is to manage the operation of a node, which can be a device, sensor, or actuator within a broader system. This controller is responsible for receiving, processing, and sending data, ensuring that the node operates efficiently and in coordination with other nodes in the network. Node controllers are often integrated into microcontrollers that allow for the execution of specific tasks, optimizing performance and energy consumption. Additionally, these controllers may include communication interfaces that facilitate interaction with other devices, which is crucial in robotics applications where synchronization and rapid response are fundamental. The relevance of node controllers lies in their ability to enable scalability and modularity of systems, facilitating the integration of new components without the need to redesign the entire system architecture.
