NVIDIA and BMW, demonstration of the future automotive factory "Digital Twin" that combines real world and virtual world
NVIDIA held a technical presentation "GTC (GPU Technology Conference) 2021" during the period from April 12 to 16 (local time), and the company's CEO Genshin Juan spoke, with reality and virtual reality, Robotics.We introduced BMW's automotive factory "Digital Twin", which operates while combining AI (artificial intelligence).
BMW has more than 40 types of models, and you can select more than 100 options for each vehicle, so there are 2100 combinations per vehicle.Therefore, the BMW factory (digital twin) made up to 10 types of vehicles per production line.
BMWの自動車工場「デジタル ツイン」When BMW designing or reconstructing a factory, using the "NVIDIA Omniverse" that allows you to simulate virtual and reality in real time, proceed with the use of different software packages such as Revit, Catia, and other point clouds., Consider the design and arrangement of the factory in 3D, and all changes are visualized in real time.
Especially in the BMW factory, the configuration change occurs regularly to respond to the release of new models, and this work may need to be performed on site, but thanks to Omniverse, workers do not need to travel.。"We have revolutionized BMW's planning process because we can do perfect simulation," said Milan Nedelicovic, a BMW AG officer.
Omniverseでのワークフローのシミュレーションでは、人間の作業員から取得したデータでデジタルヒューマンをトレーニングし、シミュレーション内の新しいワークフローのテストに投入して、作業員のエルゴノミクスや効率性を検討するというBMW's Juan states, "That's exactly why NVIDIA is focusing on digital human for simulation. Digital human training uses actual workers data."At the factory, 57,000 workers are working while sharing the workplace with robots, but the efficiency and safety of workers are improved by putting digital human in the new workflow test in the simulation.Say.
"Even if the BMW factory arrangement has been changed, the robot can adapt quickly with Omnivers, and the BMW has an intelligent robot in charge of logistics, and the flow of the manufacturing process is always on.It is improved, but the base is the NVIDIA ISAAC robotics platform, producing 2.5 million units per year, and 99 % of BMW is essential for BMW for custom production. "
It also introduces how BMW employees are monitoring work.Workers allocate various jobs in Omniverse to various robots, and can check the progress updated by sensors placed throughout the factory with real digital twin.Occasionally, humans can help robots, and when they receive the robot alert, the workers are remotely controlled the robot, and the robot guides the robot via a 5G connection while checking with the camera.Press the button once and the robot returns to work again.
Omniverse によって計画時間が短縮され、柔軟性と正確性が向上したことで、BMWの計画プロセスは30％効率化される見込みだという"NVIDIA OMNIVERSE and NVIDIA AI have opened a way to introduce simulation in 31 factories that make up the BMW manufacturing network. In addition, comprehensive workers, robots, facility buildings, assembly parts, etc.By simulating all factory models related to factory models, you will be able to support use cases that require AI, such as virtual factory planning, autonomous robot, predictive maintenance, and big data analysis.We believe that by realizing a new innovation, reducing the time spent on the plan and increasing flexibility and accuracy, we will ultimately improve the planning process by 30 %.
