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 knowledge within the technique of assembling its engines and parts. Making sense of that information, and, extra crucially, determining the place its blind spots are, was once like sorting via piles of puzzle items, in line with Boston Dynamics.
Now, with digital twin expertise and Boston Dynamics‘ Spot quadruped, the automaker stated it’s benefiting from the info it generates.
BMW produces engines, information inside Hams Corridor plant
The Hams Corridor plant machines key engine parts and assembles three- and four-cylinder inside combustion engines, in addition to V8 and V12 engines, for a variety of BMW Group automobiles. Its working quantity manufacturing throughout three machining traces totals 1.4 million parts per yr, whereas its two manufacturing amenities produce round 400,000 engines a yr.
At one level, inside groups had been utilizing over 400 customized dashboards to compile information related to their particular areas, all utilizing totally different strategies of knowledge entry. Hams Corridor wanted a “single supply of fact” that every one group members may entry.
In response, the corporate developed a totally linked digital twin of the ability. Creating the digital twin concerned integrating greater than 15 IT techniques right into a three-dimensional mannequin of the manufacturing unit that group members may entry utilizing a smartphone or pill. The dual now shows dwell manufacturing information utilizing inexperienced or purple symbols to point out the well being of a given system contained in the manufacturing unit.
BMW stated the quantity of equipment required to keep up manufacturing is immense, as is the necessity to make sure that tools 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 weak to air leaks. Regardless of the important position of this tools, 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 employees to broaden and automate inspection efforts.

Spot covers inspections
Beforehand, the manufacturing unit introduced in contractors to examine for air leaks with specialist tools. 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.
Inserting Web of Issues (IoT) sensors on tools 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 outfitted with IoT sensors that would cowl the identical quantity of space, repeating the precise measurements in difficult situations can be a fraction of the price. Boston Dynamics’ Spot robotic was the clear selection, BMW stated.
“We acknowledged we’ve got a extremely good degree of transparency now in our manufacturing information,” stated 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 wished to make use of Spot to fill these gaps. We didn’t have temperature information about all our property, or handbook dial readings and acoustic anomaly stories right 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 digital camera to measure temperature, a Fluke SV600 acoustic sensor to establish air leaks, a 360° digital camera, and lidar for 3D scanning. As these machines should 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 per week.
For 80% of its schedule, Spot makes routine inspections. Nonetheless, the opposite 20% of the time is spent wanting ahead.
Controlling Spot with a pill, a BMW group member can convey the robotic to manufacturing traces for advert hoc inspections. Workers with years of expertise and who know their tools may wish to use Spot to research a free bearing or uncommon vibration. The intern will convey Spot over to take a measurement, and the group can determine if a restore is pressing or if it will possibly wait.
“It’s nearly like finishing the loop from Spot to the digital twin and proper again down onto the manufacturing unit flooring with the upkeep associates,” stated Tomlinson. “Spot’s truly nearly totally embedded into the upkeep system.”
BMW shortly will get outcomes with Spot

Throughout the first weeks of inspections with the acoustic sensor, Christian Poss, the Innovation and Digitalization group supervisor, stated Spot discovered air leaks in surprising locations, which piqued the curiosity of group members on the manufacturing unit flooring to make sure they had been monitored often.
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.
One other clear benefit of Spot is that it doesn’t require years of expertise to function, BMW stated. That is particularly essential as a result of the corporate has an internship program for college college students. Within the U.Okay., undergraduate college students dedicate their whole third yr of research to knowledgeable internship.
Interns rotate via yearly, nevertheless, so BMW Group Plant Hams Corridor wanted expertise interns who may be taught and adapt shortly. Spot permits the I&D group to scale inspections and develop different options whereas guaranteeing a top 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 by way of how shortly we are able to roll this stuff out. Additionally, it offers these college students a extremely good internship, but it surely equally displays on how versatile the present {hardware} is.” stated 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 Might 1. It’s going to convey collectively over 5,000 builders centered on constructing robots for quite a lot of business purposes.
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 vp of engineering. He leads multidisciplinary groups to set the corporate’s technological imaginative and prescient and align analysis and growth 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.
