Inspired by the way plants grow, vine robots navigate confined and tortuous pathways by extending from their tip rather than being pushed from behind. This tip-growth minimises friction and interaction with surrounding tissue along the insertion path.

By combining controlled growth with magnetic steering, we direct these robots through delicate anatomy for minimally invasive access — enabling navigation and sampling in places that are otherwise difficult to reach safely.
