Developmental robotics is a type of robotics that uses learning algorithms to help robots learn and improve on their capabilities. The idea is to help robots gain skills and knowledge, similar to the way that humans do. The robots use sensors, programming, and basic rules to interact with their environments and get feedback from those interactions. Over time, with more data and feedback, the robot can get better at what it does. It's like a robot taking a class in school and getting better and smarter by practicing and learning from its mistakes.
