Avatar Movement

In this episode of Tech Talks, Roblox founder & CEO David Baszucki sits down with Oren Jacob and Vincent Petrella to explore our latest innovations in avatar movement. Building a fully extensible system that enables fluid, physically-based motion for characters across all shapes, sizes, and proportions is one of our most complex engineering challenges yet, requiring a full evolution of our avatar movement stack. We break down the systems behind that effort and discuss how new animation tools on Roblox are laying the foundation for more expressive avatars and more ambitious gameplay experiences.

In this episode of Tech Talks, Roblox CEO David Baszucki sits down with Nick Tornow, Lynn Gong, and Peter Yang to discuss the future of agentic game creation and how Roblox is building the next generation of tools to enable creators to build more ambitious games faster. Discover how Roblox Assistant is evolving beyond a prompt tool into an AI-native system that can plan, execute, and verify complex game development tasks alongside creators. 

In this episode of Tech Talks, Roblox Founder & CEO Dave Baszucki is joined by Kiran Bhat and Alberto Hojel for a deep dive into new techniques for creation powered by generative AI. We explore how Roblox's 3D-native foundation model builds on powerful ideas from text and image modalities, allowing creators to build functional 4D objects and worlds from prompts. We also discuss our vision for real-time video world models for gaming, leveraging our 3D simulation backbone. If you've ever wondered how AI scales to millions of players in a shared, physics-based environment, this deep dive is for you.

In this episode of Tech Talks, Roblox Founder & CEO Dave Baszucki is joined by Rajiv Bhatia (Head of Product, User & Discovery), Naren Koneru (Engineering Lead, Safety), and Eliza Jacobs (Head of Safety Policy) for a deep dive into one of the most important challenges facing online platforms today: enabling authentic communication while keeping users safe.The conversation explores Roblox’s new age estimation and age check technology, including how facial age estimation works, why it’s being introduced now, and how it fits into Roblox’s broader, layered approach to safety and civility. The group discusses the engineering breakthroughs that made this possible, the privacy-preserving design behind the system, and how policy, product, and engineering come together to create developmentally appropriate experiences for users of all ages.
