A team of researchers recently created a robot that can repair itself. The newly designed machine can sense injury to itself and adapt. That ability sets the new robot apart from earlier machines. Because the robot can recover from unexpected damage, it may be especially useful in exploring unfamiliar places. “There is a need for planetary robotic rovers(流浪者) to be able to fix things on their own,” says Josh Bongard, one of the device’s creators. “Robots on other planets must be able to continue their mission without human help if they are damaged and cannot communicate their problem back to Earth.”
A typical robot functions according to a computer program, but the new robot works differently. First, sensors in its four legs observe the robot’s movements and signals to its built-in computer. From the information it collects, the robot creates its own programs that allow it to adapt to different situations. For example, when the researchers shortened one of the robot’s legs, the smart machine simply adjusted its way of walking—it used three legs instead of four.
The researchers are looking for other places to put the resilient(迅速恢复) robot to work. One possible spot is the ocean floor. That dark and dangerous undersea terrain(地带) might be a good choice for a robot the scientists call the Starfish. “We never officially named the robot, but we usually refer to it as the Starfish, even though a real starfish has five rather than four legs,” says Bongard. “Also, a real starfish is much better than our robot at recovering from injury, because it can actually regrow its legs.” Scientists have created robots that help humans in many ways: by exploring space, fighting fires, and even performing surgery.
