Robot design is the interdisciplinary research field focused on the principles, methodologies, and processes for the conceptualization, specification, and realization of robotic systems. It investigates the integration of mechanical, electrical, and computational components to create autonomous or semi-autonomous agents capable of perceiving, processing information, and interacting physically with their environment. Key characteristics include the synthesis of multiple engineering and scientific disciplines, emphasizing performance, safety, reliability, and adaptability. Its significance lies in enabling the development of sophisticated machines for automation, exploration, assistance, and other complex tasks across various domains.
