710685Construction of a Proof-of-Concept Prototype Rescue Vehicle: Sentinel.ClosedGRD Proof of ConceptInnovate UKSentinel represents a new development in vehicles designed to operate across differing surfaces. It is technologically advanced facilitating feedback and communications between one or more locations enabling ready identification of its status and location. This project aims to construct a proof-of-concept prototype. Successful proof of concept will enable and inform a future Development of Prototype application leading ultimately to the Sentinel’s manufacture and sale. Once commercialised Sentinel will be of particular use to those requiring ready transportation over both land and water.
