"Students at the harvard microrobotics laboratory have developed a robotic bee known as 'monolithic bee' or 'mobee'. The insect is printed from layers of carbon-fiber and plastic. the combination allows for joints which are sturdy but bendable.
The bee folds up with one quick movement similar to a pop-up book, thus requiring no assembly. attached are titanium wings, which, when applied to an external power source, are able to move at 1 or 30 hertz.
This newly developed process of printing MEMS (microelectromechanical systems) can be applied to a large number of robotic devices, and is well suited to pass production."
