Grasshoppers may not spring to mind as paragons of graceful flight. But for a team of Princeton engineers, these gangly insects have inspired a new approach to robotic wings. Typical designs for ...

Engineers at Princeton University have drawn inspiration from the humble grasshopper to revolutionise tiny-robot flight. Traditionally, insect-sized flying bots have mimicked bees or flies, flapping ...

You’ve seen the SpaceX Grasshopper blast off, hover and land vertically. You’ve seen it fly higher than the Chrysler building and land vertically. Now you can see this innovative little rocket zoom ...
