NATIONAL SCIENCE FOUNDATION · DIRECTORATE FOR TECHNOLOGY, INNOVATION, AND PARTNERSHIPS (TIP)
The U.S. National Science Foundation (NSF), Directorate for Technology, Innovation and Partnerships (TIP), is soliciting Written Proposals under the NSF X-Labs Initiative for the AI for Physical Systems Topic. NSF seeks innovative, early stage platform technologies that advance intelligent, adaptive, and scalable AI systems operating in or interfacing with the physical world, including robotics, embodied systems, human robot interfaces, advanced sensing, and cyber physical systems. NSF anticipates making one or more Other Transaction (OT) awards under 42 U.S.C. § 19116.
