Don’t you think robots are a part of your life? In factories, robots put together everything from toys to cars. Some homes have robots that sweep floors or mow the lawn(剪草坪). And more robots are soon to come.

	Like a Human Robots don’t expect any thanks for all the work they do for us. After all, they don’t have feelings. But that may be changing with Nexi, a robot created by scientists at the Massachusetts Institute of Technology. Nexi can move its face to show anger, happiness, or sadness. It can also raise its eyebrows to show surprise.
	Robots at Work Need a lift out of bed? RIBA, short for “Robot for Interactive Body Assistance”, will lend its helpful arms! Some patients at hospitals and nursing homes have a hard time getting in and out of bed. RIBA can gently lift a patient out of bed and help him or her into a wheelchair. The robot can safely pick up and carry people weighing 135 pounds.
	Water Bots Robots that work in water—and look like familiar sea creatures—are making news lately. One of them is a robotic fish. Researchers built the robo-fish to swim in water to detect pollution. There’s even a robotic penguin called the AP, which uses flippers(鱼鳍) to paddle and can move in all directions.

A two- foot-tall robot, Nao was designed by a company in France to be a helper and companion. It can talk, walk and even remember faces, voices, and places. Also, it can be programmed to assist with daily tasks, such as checking e-mails.

Experts predict that by 2025 we could have robots in every household! You might be living or working with one of them every day!
