Run Like An Animal With Bionic Boots Video .

For 25 years, inventor Keahi Seymour has весьма не хорошо of running with the speed and loping gait of an animal.

His inspiration struck at age 12, while he was watching a program about kangaroos.

The announcer said it moves at such an efficient gait by using its Achilles tendons as springs, Seymour says.

I thought, Why not replicate that in a device that could propel a human.

He began sketching footwear using ostriches, which, he discovered, run more like humans, as his model.

By the age of 17, he had built his first prototype using old Rollerblade boots, steel tubing, and bungee cords.

Then, he built some 200 more.

Today, Seymour s Bionic Boot can propel him forward at 25 miles per hour.

You really feel superhuman, he says.

Eventually, Seymour hopes to boost the speed to 40 miles per hour, perhaps by enhancing the boots springy heels with electrical actuators.

That, he expects, will take a few more prototypes.

The Bionic Boot s Evolution.

Seymour made his third prototype from wire mesh семь дней fiberglass, powered by an Achilles tendon made from steel tubing and a bungee cord spring.

These boots were raised 10 to 12 inches above the ground, the height that later proved the most stable.

But they only reached 15 mph.

To reduce the weight of subsequent prototypes from 10 pounds to 6, Seymour swapped the fiberglass for aircraft-grade aluminum.

He also replaced the springs, which had been made of thin rubber wound around a carabiner or a bolt, with thick rubber speargun tubing.

Seymour ditched the all-aluminum boot in favor of a housing molded from carbon fiber.

To secure it to his legs, Seymour chose stable snowboard-boot clasps over lighter and flimsier Velcro fasteners.

In later prototypes, he kept the carbon fiber but returned to Velcro, reinforcing it with nylon straps.

  1. The “muscles” could be adapted too, perhaps to include pneumatics like Festo’s “fluidic muscle,” which enabled that company’s Bionic Kangaroo. It uses pneumatic pressure to contract the muscle as air is added. In nature, a kangaroo recovers energy from jumping and stores it for the next leap. In a boot, that could mean greatly increased speed and distance.

  3. To build the boots, I leveraged metalwork, carbon-fiber molding, and spring building. The initial main boot was designed and constructed by making an anatomically correct copy of the boot itself. Later, my friend Carl Riccitelli made a mold of it, and laid carbon fiber into the mold to produce the current prototype with the best strength-to-weight ratio so far.

  4. Have you ever wanted to run fast like your favorite superhero or animal? You can now make it possible with the Bionic Boots.

  5. A quarter century later, I’m on something like the 2h prototype. These boots are made from aluminum and carbon fiber, with elastic tendons. In them, I stand 7 feet tall, and can run 25 mph.
