机器人像生物一样吃掉其他机器来生长和修复。
Robot Metabolism: Towards machines that can grow by consuming other machines
- 用简单模块构建机器人，可吞食其他机器或环境材料
- 实验证明机器人能变大、变快、能力更强
- 适合研究可持续机器人生态与自适应系统的人
生物体具备自我修复、生长、适应和繁殖的能力，这些是持续生存与发展的关键。而当前机器人多为封闭的单一结构，难以自修、物理成长或从环境中获取材料。尽管机器人智能可通过人工智能快速进化，其身体仍为封闭系统，无法系统性整合物质实现生长或修复。本文主张，只有通过少量简单模块设计机器人，才能实现开放式的物理适应。这使机器人能机械地吞噬其他机器人或环境中的部件，并舍弃损坏部分。我们在桁架式模块化机器人平台上验证了这一原理，证明机器人可通过消耗环境材料和其他机器人实现更大体积、更快速度和更强能力。我们提出，此类机器代谢过程将是未来可持续机器人生态的重要组成部分。
原文摘要 · Abstract (English)
Biological lifeforms can heal, grow, adapt, and reproduce -- abilities essential for sustained survival and development. In contrast, robots today are primarily monolithic machines with limited ability to self-repair, physically develop, or incorporate material from their environments. While robot minds rapidly evolve new behaviors through AI, their bodies remain closed systems, unable to systematically integrate material to grow or heal. We argue that open-ended physical adaptation is only possible when robots are designed using a small repertoire of simple modules. This allows machines to mechanically adapt by consuming parts from other machines or their surroundings and shed broken components. We demonstrate this principle on a truss modular robot platform. We show how robots can grow bigger, faster, and more capable by consuming materials from their environment and other robots. We suggest that machine metabolic processes like those demonstrated here will be an essential part of any sustained future robot ecology.
