A robotic dog is a mechanical device designed to mimic the appearance and behavior of a real dog. These machines often feature sensors, cameras, and artificial intelligence, allowing them to interact with their environment and respond to commands. They can perform various tasks, such as walking, running, and even playing games, making them popular for entertainment and companionship. Many robotic dogs are used in research and development, showcasing advancements in robotics and engineering. Companies like Boston Dynamics have created models that demonstrate agility and coordination. Additionally, robotic dogs can serve practical purposes, such as assisting in therapy or providing security in certain settings.
