The tiny RoboBee from Harvard University conserves energy by using static electricity to stick to almost any surface.
The team turned to static electricity because the extremely small size of the RoboBee makes it unsuitable for traditional methods of attachments, such as adhesives. Instead, the bot is equipped with foam mount holding an electrode patch. An electric current sent through the patch will create enough static electricity to allow the bot to perch on the surface, and then detach by turning off the current.
