A Comprehensive Embodied AGI Architecture Inspired by Biological Neural Systems
Abstract
We present the Behavior Framework, a groundbreaking embodied artificial general intelligence (AGI) architecture inspired by the hierarchical structure and functionality of biological neural systems. This framework integrates reflexes, homeostatic mechanisms, emotional processing, advanced cognitive functions, and safety protocols into a cohesive software-based cognitive architecture. Designed for versatility, it is applicable across virtual contexts—such as metaverse environments, non-player characters (NPCs), and AI agents—as well as physical robotic systems. By emulating the adaptability and intelligence found in biological entities, the Behavior Framework aims to advance AGI development while ensuring ethical considerations and safety compliance. We detail each major layer of the architecture, discuss its capabilities and applications, and explore promising avenues for future research.
Introduction
The quest for artificial general intelligence requires architectures that can emulate the adaptability, learning capacity, and nuanced behaviors of biological organisms. Existing AI systems often excel in narrow tasks but lack the integrated functionality necessary for general intelligence. The Behavior Framework addresses this gap by mirroring the hierarchical structure of biological neural systems, from basic reflexes to advanced cognitive functions, all while integrating robust safety mechanisms.
Inspired by various levels of the animal kingdom—from simple reflexive organisms to complex mammals—the framework provides a scalable and adaptable architecture suitable for a wide range of applications. These include virtual environments like the metaverse, intelligent NPCs in gaming, sophisticated AI agents, and physical robots capable of complex interactions.
In this paper, we present an in-depth analysis of the Behavior Framework, detailing each layer's architecture and capabilities. By leveraging biological principles and modern computational techniques, we aim to create AGI agents that are intelligent, adaptable, and aligned with ethical guidelines.
