Subterranean Mine Inspection Using the Prometheus Re‐Configurable Drone
ABSTRACT This paper describes the design, development, and real‐world testing of an autonomous drone for subterranean exploration, known as “Prometheus.” Driven by requirements from industry that the drone be able to be deployed through areas of restricted access, Prometheus was designed to be directly deployed through a 150 mm aperture.

Abstract In South Africa, citizens in both low‐ and high‐income areas are increasingly providing their own services to mitigate the unreliability, unaffordability and inaccessibility of state services. This article examines diverse case studies across socio‐economic and residential typologies to explore shifts in service provision responsibilities from
