DEARBORN, MI—Ford Motor Co. has welcomed two new employees to its Van Dyke Transmission Plant in Sterling Heights, MI. Named Fluffy and Spot, they have four legs, and they can sit, shake hands, roll over and climb stairs.

They are not dogs, however. They are actually 70-pound quadruped robots, part of a Ford manufacturing pilot program designed to save time, reduce cost and increase efficiency.

Fluffy, the name given by the robot’s handler Paula Wiebelhaus, is one of the two models Ford is leasing from Boston Dynamics, known for creating sophisticated mobile robots. The other robot is named Spot, which is the product’s actual name.

The robots are bright yellow and easily recognizable. Equipped with five cameras, the robots can travel up to 3 mph on a battery lasting nearly two hours and will be used to scan the plant floor and assist engineers in updating the original computer aided design files for the line, which are used whenever the automaker retools the plant.

“We design and build the plant. Over the years, changes are made that rarely get documented,” says Mark Goderis, Ford’s digital engineering manager. “By having the robots scan our facility, we can see what it actually looks like now and build a new engineering model. That digital model is then used when we need to retool the plant for new products.”

Without Fluffy, the update would be far more tedious. “We used to use a tripod, and we would walk around the facility stopping at different locations, each time standing around for five minutes waiting for the laser to scan,” Goderis recalls. “Scanning one plant could take two weeks. With Fluffy’s help, we are able to do it in half the time.”

The old way also was expensive—it cost nearly $300,000 to scan one facility. If this pilot works, Ford’s manufacturing team could scan all its plants for a fraction of the cost. These cutting-edge technologies help save the company money and retool facilities faster, ultimately helping bring new vehicles to market sooner.

In time, Goderis says, the intent is to be able to operate the robots remotely, programming them for plant missions and receiving reports immediately from anywhere in the country. For now, the robots can be programmed to follow a specific path, and they can be operated from up to 50 meters away with a tablet and out-of-the-box software.

The key to Fluffy and Spot’s success is their agility, says Wiebelhaus, who controls her robot through a gaming-like device that allows her to remotely see the camera view. Should an issue occur, the control device features a safe stop that stops the robot from colliding with anything.

The robots have three operational gaits: a walk for stable ground, an amble for uneven terrain, and a special speed for stairs. They can change positions from a crouch to a stretch, which allows them to be deployed to difficult-to-reach areas within the plant. They can handle tough terrain, from grates to steps to 30-degree inclines. If they fall, they can right themselves. They maintain a safe, set distance from objects to prevent collisions.

At times, Fluffy sits on its robotic haunches and rides on the back of a small, round autonomous mobile robot, known informally as Scouter. Scouter glides smoothly up and down the aisles of the plant, allowing Fluffy to conserve battery power until it’s time to get to work. Scouter can autonomously navigate facilities while scanning and capturing 3D point clouds to generate a CAD file of the facility. If an area is too tight for Scouter, Fluffy comes to the rescue.

“There are areas in the plant that you might not want to walk into because they might be tough to maneuver,” says Wiebelhaus. “It’s easier and safer to send Fluffy back there.”

Although Fluffy is perfectly capable of rolling over, Wiebelhaus doesn’t see dog shows in his future.

“Fluffy is an amazing manufacturing tool,” says Weibelhaus. “Yes, it’s interesting and new, but Fluffy should really be valued for his work and tenacity. He can do so much more than dance and roll over. We want to push him to the limits in the manufacturing plant and see what value he has for the company.”
