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 technique of assembling its engines and elements. Making sense of that information, and, extra crucially, determining the place its blind spots are, was like sorting by piles of puzzle items, in line with Boston Dynamics.
Now, with digital twin expertise and Boston Dynamics‘ Spot quadruped, the automaker mentioned it’s benefiting from the information it generates.
BMW produces engines, information inside Hams Corridor plant
The Hams Corridor plant machines key engine elements and assembles three- and four-cylinder inside 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 services produce round 400,000 engines a 12 months.
At one level, inside groups have been utilizing over 400 customized dashboards to compile information related to their particular areas, all utilizing completely different strategies of information entry. Hams Corridor wanted a “single supply of fact” that each one group members may entry.
In response, the corporate developed a completely related 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 unit that group members may entry utilizing a smartphone or pill. The dual now shows reside manufacturing information utilizing inexperienced or pink symbols to point out the well being of a given system contained in the manufacturing unit.
BMW mentioned the quantity of equipment required to keep up manufacturing is immense, as is the necessity to make sure that gear is at all times working correctly by way of common inspections. Hams Corridor has an in depth tunnel system with pipes, chillers, and hydraulic panels which might be susceptible to air leaks. Regardless of the important position of this gear, the digital twin revealed areas of the ability the place inspection information was lacking altogether.
It was clear the Innovation and Digitalization (I&D) group wanted to help upkeep staff to increase and automate inspection efforts.

Spot covers inspections
Beforehand, the manufacturing unit introduced in contractors to examine for air leaks with specialist gear. Having the Hams Corridor upkeep group take over these handbook inspections would take hours away from time spent on precise upkeep or repairs. The I&D group turned to automation as a substitute.
Putting Web of Issues (IoT) sensors on gear was one choice for gathering automated readings, however the I&D group decided it will take years to put in all of the sensors required and show too pricey. A cellular robotic geared up with IoT sensors that would cowl the identical quantity of space, repeating the precise measurements in difficult situations could be a fraction of the price. 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 information,” mentioned Brad Tomlinson, the technical lead of Hams Corridor’s I&D group. “With that transparency, we are able to begin to establish the gaps, and we needed to make use of Spot to fill these gaps. We didn’t have temperature information about all our belongings, or handbook dial readings and acoustic anomaly studies all the way down to specifics. That’s how we’re utilizing Spot.”
Robotic makes routine inspections
Spot at present makes use of a number of sensors for inspections, together with a thermal digicam to measure temperature, a Fluke SV600 acoustic sensor to establish air leaks, a 360° digicam, and lidar for 3D scanning. As these machines need to be working 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 per 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 group member can carry the robotic to manufacturing strains for advert hoc inspections. Staff with years of expertise and who know their gear would possibly need to use Spot to analyze a unfastened bearing or uncommon vibration. The intern will carry Spot over to take a measurement, and the group can determine if a restore is pressing or if it may wait.
“It’s nearly like finishing the loop from Spot to the digital twin and proper again down onto the manufacturing unit ground with the upkeep associates,” mentioned Tomlinson. “Spot’s truly nearly absolutely 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 group supervisor, mentioned Spot discovered air leaks in surprising locations, which piqued the curiosity of group members on the manufacturing unit ground to make sure they have been monitored recurrently.
Tomlinson says an ideal instance of how the legged robotic has made operations extra environment friendly is with upkeep requests. Staff 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.
One other clear benefit of Spot is that it doesn’t require years of expertise to function, BMW mentioned. That is particularly essential 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 yearly, nevertheless, so BMW Group Plant Hams Corridor wanted expertise interns who may study and adapt rapidly. Spot permits the I&D group to scale inspections and develop different options whereas guaranteeing a high quality internship for college students. In reality, two interns lead the Spot integration program.
“We’re working with a group of younger professionals, which helps us be agile when it comes to how rapidly we are able to roll this stuff out. Additionally, it provides these college students a very good internship, but it surely 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 might be on the Boston Conference and Expo Middle from April 30 to Could 1. It should carry collectively over 5,000 builders centered on constructing robots for a wide range of business 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.
