A robotic dog is a mechanical or electronic device designed to mimic the appearance and behavior of a real dog. These machines often incorporate advanced technologies such as artificial intelligence, sensors, and actuators to emulate the movements and interactions of a living canine. Robotic dogs serve various purposes, including entertainment, companionship, therapy, and assistance in tasks like search and rescue or surveillance. They have gained popularity in both consumer markets and professional applications, offering a unique blend of technology and companionship without the responsibilities associated with caring for a real animal.
