The Department of Defense, specifically the Army, is seeking proposals for the Small Business Innovation Research (SBIR) program focused on the mechanics and control of autonomous legged robotic systems capable of navigating muddy environments. The objective is to develop a quadrupedal robot with a novel control architecture that can traverse deep mud with up to 20% leg intrusion at an average speed of 8 body lengths per minute, surpassing current capabilities. This initiative is critical for enhancing off-road autonomous locomotion, which is vital for future Army operations in challenging terrains. Interested applicants can submit Phase I proposals for up to $250,000, with a performance period of six months, and must adhere to the application deadline of July 23, 2025.
