Portable Bio-inspired Vibrational Drilling Arm

UNMET NEED

Exploring beneath the surfaces of the Moon, Mars, and remote Earth locations presents critical challenges for mining and construction purposes. Traditional geotechnical tools are too bulky and heavy for space missions, with costs escalating into the hundreds of thousands for transportation alone. Furthermore, the low gravity environments of celestial bodies diminish the effectiveness of these heavy rigs, which rely on their own weight and reaction forces for stability and drilling effectiveness. On Earth, similar challenges exist in remote or difficult-to-access areas where the logistics of transporting and assembling heavy drilling equipment are challenging in terms of feasibility, timely delivery, and costs. This situation highlights a pressing need for innovative solutions to access subsurface layers efficiently in both extraterrestrial and remote terrestrial environments.

TECHNOLOGY OVERVIEW

Prof. Maghoul and her research team propose addressing these challenges with the Bio- Inspired Vibrational Drilling Arm (BIVA), a solution inspired by the natural burrowing behaviours of snakes and sandfish. This compact, automated probe utilizes bending vibrations to fluidize surrounding granular materials, significantly decreasing penetration resistance and adapting to both low gravity environments and extreme terrestrial conditions. The BIVA’s lightweight and compact structure allow for effective operation in harsh environments such as the Moon and Mars, where traditional drilling systems fail as well as remote Earth locations. The probe prototype demonstrates up to 50 % reduction in penetration force in testing of granular materials like the lunar regolith. The soil sample used consists of fine-cutting sub-angular limestone particles, with a maximum dry density of 1950 kg/m³ and a minimum dry density of 1610 kg/m³ to meet the particle properties of lunar regolith.
