In this blog, we will explore the significance of these functions in robotics and how Amphenol's innovative connectors play a pivotal role in enabling seamless connectivity within robotic systems.
Control vs. Communication
In robotics, control refers to the ability to regulate the movement and behavior of robotic components with precision and accuracy. It involves sending signals to various subsystems, such as motors and sensors, to achieve specific tasks.
On the other hand, communication is the exchange of data between different elements of a robotic system. This includes real-time data transmission, power delivery, and coordination between the robot and external controllers.
Challenges encountered
Robotics applications demand reliable, high-performance connectors capable of withstanding harsh conditions, vibrations, and electromagnetic interference. The connectors used in robotic systems must be durable, secure, and efficient to ensure precise data flow and coordination for uninterrupted operation.
