Da Vinci's Walking Mechanical Lion Brought to Life


Leonardo Da Vinci is well known for his incredibly intricate and prophetically futuristic designs, including a legendary helicopter and blueprints for a self-propelled cart. It has only taken 500 years for someone to finally reproduce a working model of one of his most mysterious automatons (mechanized robots).

Although specific plans were never found in any of Da Vinci's works, eyewitness accounts from 1515 described a walking mechanical lion that Da Vinci created for the King of France. According to Reuters, using those accounts and Da Vinci's own sketches of mechanisms, Renato Boaretto, a "master maker of automatons," has successfully created a hand-wound robo-lion that walks, wags its tail, and opens its jaws.

World's First 3-D HDTV Remote Surgery System Allows Fantastic Precision


Oh boy, from the looks of that picture, the only perquisites for using the updated da Vinci Si surgical system are video game skills, a preference for interacting with the physical world on a high-def display, and an abnormal interest in robots. Sound like anyone you know? Intuitive Surgical's latest robotic system features two separate HD optical channels that the manufacturer claims will give "highly accurate depth perception" when merged. The surgeon console features touchpad control of the video, audio, and system settings while providing "precise, dexterous control" over an extensive array of surgical tools held by the robotic flanges. Perfect for all your minimally invasive, WebMD-inspired home surgery needs, when not performing transplants at County. Check the video after the break; 'amazing' is an understatement.

World's Smallest Helicopter to Fly at da Vinci's Birthplace

We all know the dream of the practical flying car hasn't exactly come to fruition, despite a few one-off prototypes showing some level of promise. And, while jet wing backpacks look like fun, they seem a little too extreme for most. So, perhaps our future transportation needs really lie in backpack helicopters like the GEN H-4, a personal copter set to be flown over the birthplace of Leonardo da Vinci, the man said to be the first to dream up the technology required for flight.

Da Vinci famously sketched a helicopter-looking device that would have used a large spinning-screw-shaped blade to lift itself off of the ground. It's unlikely that his concept ever flew, but the GEN H-4 does.
The contraption was designed by 75-year-old Japanese businessman Gennai Yanagisawa, and uses four engines to spin two counter-rotating blades. It's capable of airborne speeds of up to 56 mph and can be yours today for the not exactly practical price of $57,140. [Source: CNN]
