Watch This Robot Crawl on a High-Voltage Power Line

Inspection of high-voltage power lines is costly, difficult, and a dangerous job even for skilled workers. Which means it's the perfect job for a robot.

We first wrote about Expliner, an incredible inspection robot that balances on power lines like an acrobat, more than a year ago. Since then, HiBot, the Japanese company that developed Expliner, has gone on several inspection jobs, remote operating the robot as it crawls on 500-kilovolt live lines.

The company is now gearing up to deliver the robot to customers, first in Japan, and later abroad as well.

Expliner is like a wheeled cable car that rolls along the upper pair of bundled cables. In addition to its manipulator arm, it carries laser sensors, to spot corrosion or scratches, and a high-definition camera, which records details of bolts and spacers far more effectively than even a human worker.

HiBot says that Expliner is a semi-autonomous robot.

"There is always a human in the control loop, but the basic repetitive tasks are automated," says Michele Guarnieri," a HiBot co-founder. "Tasks that require a high degree of precision, like maintaining balance or moving parts to a certain angle, are also automated."

He explains that the robot can inspect up to four cables simultaneously, and software automatically checks all recorded videos and alert users about potential damages or problems on the lines.

HiBot has recently released a new video that shows off the robot's capabilities, including being able to go over cable suspension clamps through a series of acrobatic maneuvers using a dangling counterweight to shift the robot's center of gravity. Watch: 

HiBot, which spun off from the laboratory of Tokyo Tech roboticist Shigeo Hirose (known for his incredible snakebots), has recently won an award for the Expliner robot from Japan's Ministry of Economy, Trade, and Industry.

And if you're wondering, "Expliner doesn't fall," claims Guarnieri. "It's equipped with safety devices that prevent the robot from falling, even in case of strong winds."

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?
