Gecko Robotics aims to save human lives at our nation’s power plants with its wall-climbing robots that are ensuring safety in industrial and power plant facilities as they are able to go ahead of humans to check for potential hazards.

The robots can climb tanks, boilers, pipelines and other industrial equipment using proprietary magnetic adhesion, ultra-sonics, lasers and a variety of sensors to inspect structural integrity, according to a company release.

While not cheap — the robots run anywhere from $50,000 to $100,000 — they are also obviously a minuscule cost compared to human life.
