” The device uses layers of ultrathin materials that can make its wings flap 120 times a second, which is on a par with a housefly’s flapping rate. This “required tremendous innovation in design and fabrication techniques”, he adds. The robot’s wings are composed of thin polyester films reinforced with carbon fibre ribs and its ‘muscles’ are made from piezoelectric crystals, which shrink or stretch depending on the voltage applied to them.”

Micro Robots Could Prevent Blindness > ENGINEERING.com
“In the future, ophthalmologists may be able to inject Prof. Nelson’s microrobots into a patient’s eye to progressively monitor the levels of oxygen within their retinas, potentially fending off blindness.”
UAV Landing on an Air Craft Carrier > ENGINEERING.com
The Navy’s UAV, the X-47B successfully performed a cable assist landing – its first simulated aircraft carrier landing. It takes off, flies and lands within a few feet of its predicted path. In the coming months the Navy will begin testing the X-47B in live carrier landing test.
