HelicoptersHelicopters

The largest helicopter ever built was a massive aircraft developed in the Soviet Union during the 1960s called the Mil V-12. The V-12 was a rather unusual test vehicle that featured two rotors mounted side by side at the ends of a large wing. Each rotor had a diameter of nearly 115 ft. The helicopter was so enormous that the distance from the edge of one rotor disk to the other was almost 220 ft, even wider across than the wingspan of a Boeing 747!

Picoflyer is the world’s smallest helicopter. It is about the size of a 9v battery and can fly for about a minute on a full charge.

PlanesPlanes

The Antonov An-225 is the world’s largest plane and has a wingspan of 290 feet (a football field) and can carry 550,000 pounds of cargo

The Bumble Bee II – is the world’s smallest plane and has a wingspan of 5½ feet.

This microrobot is about as wide as a human hair and half the length of the period at the end of a sentence. But it can move forward and turn. While not an “intelligent robot” it is by far the smallest to date.

The KUKA KR 1000 titan 6-axis robot is listed as the largest and strongest robot (at least industrial robot) and can pick up 1,000 kg (about 2,500 pounds) and reach out about 10’ from it’s base. Perfect for putting a motor into a car or something similar. The robot stands about 12 feet tall

Nanocar from Rice Nanocar from Rice UniversityUniversity

Nanocar is constructed by building a molecule has four wheels that are free to rotate when attached to a gold surface.

When heated to about 200 degrees, the wheels become mobile and an engine built into the center of the chassis rotates when light is shone on the molecule.

This is an excellent example of molecular and chemical engineering
