BMW acquired a Spot quadruped from Boston Dynamics to conduct automated inspections in 2023. | Supply: Boston Dynamics
BMW Group’s Hams Corridor plant close to Birmingham, England, generates oceans of information within the strategy of assembling its engines and elements. Making sense of that knowledge, and, extra crucially, determining the place its blind spots are, was once like sorting by way of piles of puzzle items, in accordance with Boston Dynamics.
Now, with digital twin expertise and Boston Dynamics‘ Spot quadruped, the automaker mentioned it’s taking advantage of the info it generates.
BMW produces engines, knowledge inside Hams Corridor plant
The Hams Corridor plant machines key engine elements and assembles three- and four-cylinder inner combustion engines, in addition to V8 and V12 engines, for a spread of BMW Group automobiles. Its working quantity manufacturing throughout three machining strains totals 1.4 million elements per 12 months, whereas its two manufacturing amenities produce round 400,000 engines a 12 months.
At one level, inner groups had been utilizing over 400 customized dashboards to compile knowledge related to their particular areas, all utilizing completely different strategies of information entry. Hams Corridor wanted a “single supply of fact” that each one workforce members may entry.
In response, the corporate developed a completely linked digital twin of the ability. Creating the digital twin concerned integrating greater than 15 IT methods right into a three-dimensional mannequin of the manufacturing facility that workforce members may entry utilizing a smartphone or pill. The dual now shows stay manufacturing knowledge utilizing inexperienced or pink symbols to indicate the well being of a given system contained in the manufacturing facility.
BMW mentioned the quantity of equipment required to keep up manufacturing is immense, as is the necessity to make sure that tools is all the time working correctly through common inspections. Hams Corridor has an intensive tunnel system with pipes, chillers, and hydraulic panels which might be susceptible to air leaks. Regardless of the essential position of this tools, the digital twin revealed areas of the ability the place inspection knowledge was lacking altogether.
It was clear the Innovation and Digitalization (I&D) workforce wanted to help upkeep staff to develop and automate inspection efforts.

Spot covers inspections
Beforehand, the manufacturing facility introduced in contractors to examine for air leaks with specialist tools. Having the Hams Corridor upkeep workforce take over these guide inspections would take hours away from time spent on precise upkeep or repairs. The I&D workforce turned to automation as a substitute.
Putting Web of Issues (IoT) sensors on tools was one possibility for gathering automated readings, however the I&D workforce decided it will take years to put in all of the sensors required and show too pricey. A cell robotic outfitted with IoT sensors that might cowl the identical quantity of space, repeating the precise measurements in difficult circumstances can be a fraction of the fee. Boston Dynamics’ Spot robotic was the clear alternative, BMW mentioned.
“We acknowledged we now have a very good stage of transparency now in our manufacturing knowledge,” mentioned Brad Tomlinson, the technical lead of Hams Corridor’s I&D workforce. “With that transparency, we will begin to determine the gaps, and we wished to make use of Spot to fill these gaps. We didn’t have temperature knowledge about all our belongings, or guide dial readings and acoustic anomaly stories all the way down to specifics. That’s how we’re utilizing Spot.”
Robotic makes routine inspections
Spot at the moment makes use of a number of sensors for inspections, together with a thermal digicam to measure temperature, a Fluke SV600 acoustic sensor to determine air leaks, a 360° digicam, and lidar for 3D scanning. As these machines need to be operating 24/7, they’ve precedence on auto walks so a schedule is created for a sure station to be inspected as soon as a day, and one other station as soon as every week.
For 80% of its schedule, Spot makes routine inspections. Nonetheless, the opposite 20% of the time is spent trying ahead.
Controlling Spot with a pill, a BMW workforce member can deliver the robotic to manufacturing strains for advert hoc inspections. Workers with years of expertise and who know their tools may need to use Spot to research a unfastened bearing or uncommon vibration. The intern will deliver Spot over to take a measurement, and the workforce can determine if a restore is pressing or if it may wait.
“It’s virtually like finishing the loop from Spot to the digital twin and proper again down onto the manufacturing facility flooring with the upkeep associates,” mentioned Tomlinson. “Spot’s truly virtually totally embedded into the upkeep system.”
BMW rapidly will get outcomes with Spot

In the course of the first weeks of inspections with the acoustic sensor, Christian Poss, the Innovation and Digitalization workforce supervisor, mentioned Spot discovered air leaks in sudden locations, which piqued the curiosity of workforce members on the manufacturing facility flooring to make sure they had been monitored recurrently.
Tomlinson says an ideal instance of how the legged robotic has made operations extra environment friendly is with upkeep requests. Workers can now log into the digital twin, zoom into particular areas to view Spot’s inspection particulars, and submit a upkeep request proper there on display screen.
One other clear benefit of Spot is that it doesn’t require years of expertise to function, BMW mentioned. That is particularly necessary as a result of the corporate has an internship program for college college students. Within the U.Ok., undergraduate college students dedicate their whole third 12 months of research to an expert internship.
Interns rotate by way of yearly, nonetheless, so BMW Group Plant Hams Corridor wanted expertise interns who may be taught and adapt rapidly. Spot permits the I&D workforce to scale inspections and develop different options whereas guaranteeing a high quality internship for college kids. In truth, two interns lead the Spot integration program.
“We’re working with a workforce of younger professionals, which helps us be agile when it comes to how rapidly we will roll these items out. Additionally, it provides these college students a very good internship, however it equally displays on how versatile the present {hardware} is.” mentioned Tomlinson.

Boston Dynamics to keynote Robotics Summit
Aaron Saunders, chief expertise officer at Boston Dynamics, will give a keynote speak on the Robotics Summit & Expo. The present will likely be on the Boston Conference and Expo Middle from April 30 to Could 1. It would deliver collectively over 5,000 builders centered on constructing robots for a wide range of industrial functions.
Saunders will open the second day of the present with a session on “Redesigning Atlas: Boston Dynamics on the Way forward for Humanoids.”
With over 20 years at Boston Dynamics, Saunders has held key roles, together with vice chairman of engineering. He leads multidisciplinary groups to set the corporate’s technological imaginative and prescient and align analysis and improvement with enterprise wants. Saunders holds a grasp’s in mechanical engineering from the College of Victoria and a bachelor’s from the College of Alberta.
