Robotics and artificial intelligence (AI) have different purposes but they a common field which is artificially intelligent robots. Robotics is an interdisciplinary branch of engineering and science, which investigate the design, construction, operation, and use of robots, as well as computer systems for their control, sensory feedback, and information processing. As a branch of Computer Science, AI is the study of any device that perceives its environment and takes actions that maximize its chance of successfully achieving its goals. Many AI algorithms keeps learning, so that they can enhance themselves by learning new heuristics, or can themselves write other algorithms.
Robots serve different purposes, but people want it to be more “intelligent” to assist with more complicated tasks and survive more disturbing environments. To approach to artificially intelligent robots, a more intelligent version, the researches refer to the knowledge from both robotics and artificial intelligence fields. People mimic the human mind to improve the intelligence of the robots. Actually, the development of the artificial intelligent robots is a process of better understanding we human beings. Just as physical robotic design is a handy tool for understanding animal and human anatomy, AI research is useful for understanding how natural intelligence works. The challenge of the AI part is exactly to understand the natural intelligence process.
