A、A dog that runs on three legs. B、New robot dogs developed by scientists. C、New robots that can help people in natural disaster

When a dog loses a leg, the animal eventually figures out the best way to get around on three legs. In a short time, the dog learns to deal with its physical disability. Now, scientists have developed robots that behave in much the same way. We can find robots everywhere. Robots build cars, play chess and can clean your house. They may someday drive your car, too. Robots also help people in natural disasters. Robots are deployed in search and rescue operations following an earthquake. Robots can be sent to a lot of places said to be unsafe. The problem is that all of those types of situations and environment are extremely unpredictable and hostile. And it is very likely that robots and humans in those situations become damaged. The scientists are developing technology so that robots will continue operating after the first sign of injury.
