A robot is a machine, programmable by a computer, capable of carrying out a complex series of actions automatically. Robots can be guided by an external control device or the control can be embedded within.
Robots have replaced humans in performing repetitive and dangerous tasks, or task people are unable to do because of size limitations or take place in extreme environments such as outer space or at the bottom of the sea.
Robots are blamed for job loss as they replace workers in increasing numbers. And the increasing use of robots in warfare and combat raises ethical concerns especially once robots are given some degree of autonomy through AI.
Robots can be humanoid or machines designed to perform a task with no regard for how they look. Robots are used in factories for managing manufacturing processes, in medicine for assisting surgeons in operations, in hospital and homes for assisting patients, in the air as drones assisting farmers, miners, utilities, developers and in environments that are dangerous or difficult to access otherwise, on farms, in mines, on roads and in homes, schools and households.
Robotics is a new branch of engineering and science that includes mechanical engineers, electronic engineering, information engineering and computer science. Robotics deals with the design construction, operation and use of robots as well as computer systems for control, feedback and information processing.
Whether robots are used commercially, domestically or by the military, there will be increasing demand for people capable of servicing and supporting robots in all industries and environments.
