One step beyond automated machines is the industrial robot, the heart arid brain of which is the microcomputer. Unlike most automated machines, industrial robots can be programmed to do a variety of tasks that are usually accompanied by human factory workers. Like their human counterparts, industrial robots can be switched from one job to another and can be programmed to handle new tasks. Thus far, robots have found their greatest use in assembling mechanical components. However, they are swiftly branching from basic assembly operations to construction and mining, and their most glamorous use of all, the exploration of oceans and outer space.
