Social robots are machines designed to interact with humans in a social manner. They can recognize speech, respond to emotions, and engage in conversations, making them useful in various settings like homes, schools, and hospitals. These robots often use artificial intelligence to learn from their interactions and improve over time. Many social robots are created to assist with tasks such as companionship, education, or therapy. For example, Pepper is a well-known social robot that can communicate and understand human emotions, while Paro is a therapeutic robot designed to provide comfort to patients.
