给AI一个“身体”：3D数字人是具身智能的解法？｜机器人系列

Key Concepts & Industry Focus - 3D digital humans are seen as a crucial link between the virtual and real worlds, evolving beyond AI avatars to become a "embodied intelligence driving layer" [1] - The industry faces the challenge of balancing high quality, low latency, and low cost in 3D digital human creation, while achieving "generalization" across diverse scenarios [1] - The report explores the potential future where screens can interact, NPCs evolve, and robots empathize, questioning the evolving relationship between humans and AI and the proximity to a "digital life" era [1] Technical Aspects & Challenges - The development of 3D digital humans involves the fusion of large models and robotics, acting as a bridge to embodied intelligence [1] - Two main technical paths exist: 2D "speaking" and 3D "expressing," with the latter focusing on building an embodied intelligence driving layer through five key stages [1] - Key challenges include high modeling costs and scarcity of high-quality data, along with achieving generalization in interaction, motion, and emotion [1] Applications & Future Implications - 3D digital humans have the potential to revitalize screens by enabling more natural human-computer interaction through "natural dialogue" [1] - Virtual IPs can evolve into "digital idols," allowing NPCs and players to engage in collaborative adventures [1] - 3D digital humans are accelerating the evolution of robots, driving the arrival of the embodied intelligence era [1]
