The dual-reciprocating drill (DRD) is a low-mass alternative to traditional drilling techniques biologically inspired by the wood wasp ovipositor, which is used to drill into wood in order to lay its eggs. The DRD reciprocates two halves lined with b

This article presents a novel hybrid evolution of the biologically-inspired dual-reciprocating drill (DRD). The proposed system combines the reciprocation motion used by previous iterations of the wood wasp drill with a proposed new undulatory/oscill

Recent remote sensing missions have established the presence of water-ice in permanently shadowed regions (PSRs) located at the lunar poles, offering the possibility of a source of material for future in situ resource utilisation (ISRU). ISRU offers

Two laboratory test series were performed with the aim of ensuring the proper functionality of the key sampling mechanisms installed aboard the Mars rover ExoMars, currently scheduled for launch in 2020 by the European Space Agency ESA. In order to f

The dual-reciprocating drill (DRD) is a biologically-inspired low-mass alternative to traditional drilling techniques, using backwards-facing teethed halves to grip the surrounding substrate, generating a traction force that reduces the required over

The Powdered Sample Dosing and Distribution System (PSDDS) of the ExoMars rover will be required to handle and contain samples of Mars regolith for long periods of time. Cementation of the regolith, caused by water and salts in the soil, results in c

As icy regolith is believed to exist in the subsurface of permanently shadowed areas near the lunar south pole, there is a growing interest in obtaining samples from these polar regions. To qualify for spaceflight, sampling instruments must demonstra
