The team will build a tiny, five-segment crawling robot (about the size of a small pen cap) that can inch its way through the body to hard to reach places. It can take tissue samples from the sinuses and  navigate fluid-filled spaces in the brain to connect ventricles and help reduce dangerous pressure. The middle segments are powered by a novel magnet-driven pump that controls micro-hydraulic suction cups as feet. The team has demonstrated core capabilities and will work to miniaturize and automate the technology through development of new improved actuators, sensors, electronics, and AI-backed navigation. The team will demonstrate essential function in cadavers within Phase 1; in Phase 2, the team will demonstrate advanced navigation and automated interventions in a large animal model (pigs) as well as engage with FDA through the presubmission process.
