The electric car has changed the process of building cars, and the move towards self-driving is reshaping the future of "mobility". The redefinition of mobility also means that it will face various challenges of rapid evolution, and the use of virtual and real integrated fields for advance simulation testing and validation will be the key to shortening R&D time and reducing development costs. In this presentation, we will share the Foundry Factory built by HHRI, a foundry that breeds creativity and solutions.
