The Guardian S is a multi-purpose, man-portable, wirelessly-controlled, unmanned ground vehicle, capable of traversing challenging terrain, climbing vertically and even inverted, that acts as a robotic mobile Internet of Things (IoT) platform to carry multiple sensor payloads. It is designed to collect data in confined or enclosed spaces, or circumstances that require hours, not minutes, of data collection, or where data can only be collected by placing sensors in close proximity to, or in contact with, a surface.
