Snakebot Worms Its Way Into Your Heart, Literally

CardioARM, a snake robot from CMU, is designed to navigate around your heart, since what we all definitely need are more robot snakes in our chests

Snakebot Worms Its Way Into Your Heart, Literally

Next time you need heart surgery, this little snakebot is going to make himself right at home deep inside your chest via a small hole in your solar plexus. It's CardioARM, and don't panic, he's here to help. Developed by CMU's Howie Choset, CardioARM has 102 joints (plus a camera for a head) and can be directed to slither around your vital organs with the utmost precision, making it unnecessary to 'crack open your chest,' which is apparently what they normally do when your ticker needs an overhaul.

Last February, CardioARM was successfully tested on a human for the first time, performing a diagnostic heart mapping procedure, which sounds like it was probably a pile o' fun for everyone involved. Dr. Choset has bigger plans for his snakebots, though:

"He hopes to test the device in other surgeries, such as ablation—which involves burning away a small amount of heart muscle to correct an abnormal beat."

Burning? Burning, you say? What, with lasers? We're giving these flesh-burrowing robot snakes lasers now? What else?!

“We’re hoping to use a remote-controlled robot to go through small caves in Egypt,” [Choset] says, “and find remains of ancient Egyptian tombs.”

Snakebots. Lasers. Ancient Egyptian tombs. Wow, I smell a blockbuster...

The Bionic-Hand Arms Race

The prosthetics industry is too focused on high-tech limbs that are complicated, costly, and often impractical

A photograph of a young woman with brown eyes and neck length hair dyed rose gold sits at a white table. In one hand she holds a carbon fiber robotic arm and hand. Her other arm ends near her elbow. Her short sleeve shirt has a pattern on it of illustrated hands.

In Jules Verne’s 1865 novel From the Earth to the Moon, members of the fictitious Baltimore Gun Club, all disabled Civil War veterans, restlessly search for a new enemy to conquer. They had spent the war innovating new, deadlier weaponry. By the war’s end, with “not quite one arm between four persons, and exactly two legs between six,” these self-taught amputee-weaponsmiths decide to repurpose their skills toward a new projectile: a rocket ship.

The story of the Baltimore Gun Club propelling themselves to the moon is about the extraordinary masculine power of the veteran, who doesn’t simply “overcome” his disability; he derives power and ambition from it. Their “crutches, wooden legs, artificial arms, steel hooks, caoutchouc [rubber] jaws, silver craniums [and] platinum noses” don’t play leading roles in their personalities—they are merely tools on their bodies. These piecemeal men are unlikely crusaders of invention with an even more unlikely mission. And yet who better to design the next great leap in technology than men remade by technology themselves?
