Robotic controllers are devices that manage the movements and actions of robots. They interpret commands from a user or a computer program and translate them into signals that control the robot's motors and sensors. This allows the robot to perform tasks such as picking up objects, navigating spaces, or assembling products. These controllers can vary in complexity, from simple remote controls to advanced systems using artificial intelligence. They often include software that enables programming and real-time adjustments. Common applications of robotic controllers can be found in industries like manufacturing, healthcare, and automotive production.
