# Flexible Vine Robots Notre Dame's SPROUT Snakes 30 Feet Into Collapsed Rubble By Adam Harrie | Written with AI assistance | Published 2026-09-29 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/flexible-vine-robots References: [prnewswire](https://www.prnewswire.com/news-releases/search-and-rescue-robot-designed-to-help-first-responders-find-survivors-beneath-collapsed-structures-302892908.html)  Notre Dame is developing 'SPROUT,' a flexible [vine robot](https://www.trendhunter.com/trends/mushroom-robot) that allows rescue crews to inspect collapsed structures before entering unstable debris. In collaboration with emergency response teams, the university is shaping the Soft Pathfinding Robotic Observation Unit, or SPROUT, to navigate rubble and help locate trapped survivors. The robot can reach up to 30 feet into narrow gaps, carrying a camera that gives crews a view beyond pole-mounted search cameras. [Acoustic sensors](https://www.trendhunter.com/trends/sniff-robot) along its body could also trace a path through debris, helping responders narrow the search and identify a safer entry. In this category, SPROUT points to [search-and-rescue robotics](https://www.trendhunter.com/trends/robot-dog-concept) designed with first responders in mind, rather than apart from them. That could push future systems to offer route guidance before crews commit personnel to a dangerous interior space.
