自主机器人是一种由信息处理单元引导机械执行器通过一系列状态来执行预先设计的功能的系统，预计将给从医疗保健到交通运输的所有领域带来革命性的变化。从医学到环境修复，微型机器人也将迎来一场类似的革命。开发这些微型机器人的一个关键障碍是信息系统的集成，特别是在商业铸造厂制造的电子产品与微执行器的集成。在这里，我们开发了这样的集成工艺，并建立了由船上互补金属氧化物半导体电子设备控制的微型机器人。由此产生的自主、不受束缚的机器人大小为100至250微米，由光供电，行走速度超过每秒10微米。此外，我们还演示了一个可以响应光学命令的微型机器人。这项工作为无处不在的自主微型机器人铺平了道路，这些机器人可以执行复杂的功能，对环境做出反应，并与外部世界进行交流。
Autonomous robots-systems where mechanical actuators are guided through a series of states by information processing units to perform a predesigned function-are expected to revolutionize everything from health care to transportation. Microscopic robots are poised for a similar revolution in fields from medicine to environmental remediation. A key hurdle to developing these microscopic robots is the integration of information systems, particularly electronics fabricated at commercial foundries, with microactuators. Here, we develop such an integration process and build microscopic robots controlled by onboard complementary metal oxide semiconductor electronics. The resulting autonomous, untethered robots are 100 to 250 micrometers in size, are powered by light, and walk at speeds greater than 10 micrometers per second. In addition, we demonstrate a microscopic robot that can respond to an optical command. This work paves the way for ubiquitous autonomous microscopic robots that perform complex functions, respond to their environments, and communicate with the outside world.
