Can

Definition

In the context of mechatronic system integration, a 'can' refers to a type of communication protocol known as Controller Area Network (CAN). This robust vehicle bus standard allows microcontrollers and devices to communicate with each other without a host computer, enabling seamless integration of various components in a system. The CAN protocol is essential for real-time control and monitoring in complex systems, making it a vital aspect of mechatronic design.
