The FRR (Foundational Research in Robotics) program, jointly led by the CISE and ENG Directorates, supports research on robotic systems with high computational capability and physical complexity. A robot is defined as an engineered construct with intelligence, capable of processing information, sensing, planning, and interacting with its environment. The program welcomes research that integrates questions of intelligence, computation, and embodiment. Proposals should focus on foundational advances in robotics, addressing fundamental gaps in the field and aiming to endow robots with new or enhanced capabilities. Experimental validation on a physical platform is encouraged. Projects not directly contributing to the science of robotics or better suited for other NSF programs should not be submitted to FRR. Potential investigators are advised to consult with an FRR Program Officer before submission. Non-compliant proposals may be returned without review.
