A clever flute-playing robot offers an impressive rendition of Flight of the Bumblebee. Its “lungs” consist of a bellow that moves air in and out, and its “tongue” can block air in two places to transition between notes. Its “vocal cords” are a vibrato device that can change vibrations according to the air flow, and it even has elastic “lips” that can control its airstream, changing in width, thickness, and angle as it plays.
Bacteria (fast white spots) swim through human blood in a microfluidic substrate with guidance from an MRI machine. The bacteria swim against the current, past red blood cells (slower white spots).

An assistive robot at Georgia Institute of Technology, called El-E, can open drawers, doors and even a microwave by grasping affixed towels, much in the same way a service dog would. El-E can also follow verbal commands, such as “tug it” or “tug it down.” An assistive robot like this could benefit those with disabilities or the elderly living at home.

This animated cartoon is projected by a 635-nanometer scanning laser at eight kilohertz onto a flexible plastic screen. Screens that fluoresce blue, green, and yellow-red could eventually be combined to create a full-color display.
An autonomous helicopter performs a slew of tricks using a flight path based on video analysis of the maneuvers. The helicopter automatically adjusts its course during flight to account for changes in wind speed.
