Aardvark hole-diggers come equipped with 3-dimensional macro-maps. They allow the user to see exactly where they are when underground. Radar functionality allows them to see through the ground to other machines and other tunnels, with a range of 25 miles. Infra-red functionality allows it to assess soil type and density at a range of up to 5 miles. Infra-green functionality allows it to spot living/breathing creatures underground with a range of up to 1 mile.
The upgrade, the 4D Macro-map is scheduled to be released next year. So it will be able to generate underground maps in 4 dimensions, i.e.
[1] width
[2] breadth
[3] height
[4] smell
Because of the extremely sensitive nature of the technology used in it, unfortunately we are not able to give more information about it at this stage, but we can confirm the device will be able to smell, and what it smells will be fully integrated into the user experience, either visually on the screen, or via ossicles inserted into the user’s nostril.
