In a room at Stanford University, scientists have a problem with their robot. It can walk up and down walls made of glass and plastic, but it can’t walk upside down. So today they have a gecko in the room and they are studying how it walks. It’s an amazing animal. Like the robot, it’s very good at moving up and down trees, but the gecko can also walk upside down. In particular, the scientists are interested in the gecko’s feet. They want to learn from its feet and use the same design on their robot.<br>Two types of sea animals helped engineers in Canada and Germany. When engineers in Canada were working on improving wind turbines, they studied a whale’s flippers because these animals move so easily through water. And when the car company Mercedes-Benz wanted to think of a new design for a car, they looked at a boxfish. The result was a car that was very similar to the shape of a boxfish and that used less fuel than other cars.<br><br>Scientists at Stanford University are designing their robot’s feet base on the study of the gecko.<br><br>The car was designed according to the shape of a boxfish, and the wind turbine was improved by the design of the whale’s flippers.<br><br>A robot at Stanford University can walk upside down similar to how a gecko does.<br><br>Engineers from Canada studied the boxfish and those in Germany paid attention to the whale.
