一句话总结

本文提出了一套物理系统自主性的基础科学，主张通过系统化、跨学科的框架来推进交通、医疗、制造和家庭辅助等领域的自主技术发展。它描绘了未来自主系统在提升安全性、生产效率和生活质量方面的愿景，同时指出了在可靠性、人机交互和伦理部署方面面临的核心挑战。

ABSTRACT

Our lives have been immensely improved by decades of automation research -- we are more comfortable, more productive and safer than ever before. Just imagine a world where familiar automation technologies have failed. In that world, thermostats don't work -- you have to monitor your home heating system manually. Cruise control for your car doesn't exist. Every elevator has to have a human operator to hit the right floor, most manufactured products are assembled by hand, and you have to wash your own dishes. Who would willingly adopt that world -- the world of last century -- today? Physical systems -- elevators, cars, home appliances, manufacturing equipment -- were more troublesome, ore time consuming, less safe, and far less convenient. Now, suppose we put ourselves in the place someone 20 years in the future, a future of autonomous systems. A future where transportation is largely autonomous, more efficient, and far safer; a future where dangerous occupations like mining or disaster response are performed by autonomous systems supervised remotely by humans; a future where manufacturing and healthcare are twice as productive per person-hour by having smart monitoring and readily re-tasked autonomous physical agents; a future where the elderly and infirm have 24 hour in-home autonomous support for the basic activities, both physical and social, of daily life. In a future world where these capabilities are commonplace, why would someone come back to today's world where someone has to put their life at risk to do a menial job, we lose time to mindless activities that have no intrinsic value, or be consumed with worry that a loved one is at risk in their own home? In what follows, and in a series of associated essays, we expand on these ideas, and frame both the opportunities and challenges posed by autonomous physical systems.

研究动机与目标

• 建立物理系统自主性的科学基础，超越临时性的自动化，迈向有原则的、可扩展的设计。

• 识别实现自主物理系统负责任且有效部署所必需的关键研究与政策挑战。
• 倡导开展协调一致的、跨学科的研究工作，将自主性正式确立为一门科学学科，类似于热力学或控制理论。

提出的方法

• 提出一种基于视觉的自主框架，整合感知、决策与行动，适用于动态、现实世界环境。
• 强调需要建立形式化自主模型，以涵盖不确定性、适应性及人类监督等因素。
• 借鉴机器人学、控制理论与人机交互的原理，定义自主系统的核心组件。
• 主张开发形式化验证与确认技术，以确保自主物理系统的可靠性与安全性。
• 强调在自主系统部署中，人类在回路监督与伦理设计的重要性。
• 呼吁在计算机科学、工程学与社会科学之间建立统一的研究议程，以应对自主性中的系统性挑战。
