It takes a moment for the senses even to comprehend BigDog, a four-legged robot that vaguely resembles a headless pack animal.
The machine's creator, Boston Dynamics, has a motto — “dedicated to the way things move” — and that’s precisely what is both jarring and fascinating about its invention. Using a gasoline engine that emits an eerie lawnmower buzz, BigDog has animal-inspired articulated legs that absorb shock and recycle kinetic energy from one step to the next
Enter the K-MAX, a remote-controlled helicopter designed to transport heavy loads — even in Afghanistan's high altitudes.
The K-MAX's unique rotor design — two intermeshed rotors turning in opposite directions and slightly angled to prevent the blades from colliding — give this unmanned aircraft a distinct advantage.
“All the energy goes into the lift and eliminates the need for the tail rotor,” said Frans Jurgens, spokesman for Lockheed Martin Corporation, which manufactures the K-MAX.
Funny satire of Project look closely.
