A robotic device is an AUTOMATON, which is a machine that can perform tasks autonomously or with minimal human intervention. It is typically programmed to carry out specific tasks and can be used in a variety of applications, such as manufacturing, healthcare, and transportation. Robotic devices are becoming increasingly popular due to their ability to increase efficiency and accuracy while reducing costs. They are also able to work in hazardous environments, such as nuclear power plants, where humans cannot go.
