If you want to find cats in images, you need to train an image recognition algorithm with thousands of images of cats and thousands of images of backgrounds that do not contain cats. Needless to say, this algorithm can only understand objects/classes it has learned. Changed Technology: Today we have shifted our technology from analog to digital data communication and storage, which makes the change a convinient approach.
Nowadays, robotics has made many advantages in the robots designing. They are able to take physical interaction of human being as a useful information. They can react to any physical interaction to perform the output task. This technology has made the change in robotics which has become an advantageous component in the era of Artificial Intelligence.
