Robotics in Manufacturing<\/h2>\n\n
The field of robotics in manufacturing has a promising future, from humanoid robots to industrial automation systems. However, while the demand for industrial robotics continues to grow, the challenges associated with its adoption remain. <\/p>\n\n
The adoption of industrial robotics typically faces three major obstacles:<\/p>\n\n
\n
High investment costs and material constraints<\/strong><\/li>\n\n\n\n
Long development cycles<\/strong><\/li>\n\n\n\n
Limited data for testing and Machine Learning training<\/strong><\/li>\n\n\n\n
Safety risks, for both material and operators<\/strong><\/li>\n<\/ul>\n\n
These constraints slow down innovation and can make for a tough barrier to entry to advanced robotics, especially to SMEs.Qu\u2019est-ce qu\u2019un jumeau num\u00e9rique ?<\/p>\n\n
What is a digital twin?<\/strong><\/h2>\n\n
Digital Twins address these challenges through high-fidelity virtual replicas of real robotic systems. By creating realistic simulations of complex environments, they enable engineers and researchers to test, train and iterate on their work before deploying anything in the real world, and to painlessly monitor and control installations already in place. <\/p>\n\n
Through the AI-MATTERS project and the PRISM platform, CEA-List aims to create immersive digital twins that drastically reduce both time and costs by accurately mirroring complex robotics systems, at a fraction of their cost.<\/p>\n\n
Overcoming constraints: Digital Twins as a catalyst for Data-Driven Robotics<\/strong><\/h2>\n\n
Digital twins transform the robotics development pipeline by reducing the need for real world tests and therefore limiting expensive failures. They can also accelerate and improve testing, by running many more scenarios, more complex and diversified than possible in reality. <\/p>\n\n
Additionally, they can present engineers with the possibility of generating as much data as necessary for AI training, benchmark, risk assessment or predictive maintenance. In that way, digital twins not only limit financial and time investments, they also unlock new horizons for industrial applications. <\/p>\n\n<\/figure>\n\n

Projecting reality with accurate real time physics<\/strong><\/h2>\n\n
At the core of our immersive digital twins stands XDE Physics, a real time physics engine developed at CEA-List specifically for robotics and manufacturing, with applications in the automotive, aeronautics, energy, and healthcare industries.This engine is designed as an out-of-the-box solution that can be seamlessly integrated with mainstream 3D engines, such as Unity, Unreal Engine 5 and NVidia’s Omniverse, aiming to be as multiplatform as possible, and cover a wide variety of use cases.<\/p>\n\n

Use cases<\/strong><\/h2>\n\n
Factory digital twin for manufacturing & photorealistic 3D scans:<\/strong><\/p>\n\n
With digital twins being much faster, cheaper and easier to build than real factories, they can be used to predict performance, anticipate problems, and refine plans before materials are even bought.<\/p>\n\n
As a proof of concept, we built a simplified model of a fully autonomous tricycle assembly line, in a demo allowing users to update it on the fly, both in Virtual Reality (VR) headsets and on their computer screen.<\/p>\n\n
We also incorporated a 3D scan of the empty building into the digital twin, in order to preview the final look of the assembly line inside the building, all from a computer.<\/p>\n\n
