See Spot Scan: Ford Deploys Robot Dog

To help make the process faster and cheaper, Ford recently sought the help of a four-legged robot dog made by Boston Dynamics, a subsidiary of Japanese conglomerate SoftBank Group Corp. "It's a huge breakthrough for us," said Mark Goderis, digital engineering manager at Ford. The robot, nicknamed "Fluffy" by one of Ford's digital engineers, weighs 70 pounds and is equipped with five cameras that give it 360-degree vision, letting it observe what's in front of it and avoid obstacles. It can climb stairs and stabilize itself on slippery surfaces and metal grates using optimization algorithms. It can also access hard-to-reach areas within the plant, as long as they are at least 2 feet wide. The robot dog, officially called "Spot" by Boston Dynamics, costs $74,500.
