Robotics engineers are engineering technologists who apply principles from mechanical, manufacturing and electrical engineering to design and test robots, automated systems and new applications.
The field of computer science and engineering concerned with creating robots, devices that can move and react to sensory input. Robotics is one branch of artificial intelligence.Robots are now widely used in factories to perform high-precision jobs such as welding and riveting.They are also used in special situations that would be dangerous for humans -- for example, in cleaning toxic wastes or defusing bombs.obotics is one branch of artificial intelligence.
