Effective elastic modulus of isolated gecko setal arrays

The hypothesis that Eeff of gecko setae falls within Dahlquist's criterion for tack is tested, the validity of a model of setae as cantilever beams is evaluated, and highly linear forces of deformation under all compression conditions support the cantilevers model.

A framework for the coordination of legged robot gaits

The present preliminary experiments with these new gaits suggest that they may permit for the first time locomotion over extremely rough terrain that is almost as reliable, rapid, and energy efficient as the very fastest or most efficient outcomes centralized feedforward gaits can achieve on level ground.

Piecewise linear homeomorphisms for approximation of invertible maps.

Towards an in vivo biologically inspired nanofactory.

It may, however, be possible to go even further and design 'pseudo-cell' nanofactories that work with molecules already in the body to fight disease.

Automated gait adaptation for legged robots

This paper presents a system for gait adaptation in the RHex series of hexapedal robots that renders this arduous process nearly autonomous, by recourse to a modified version of Nelder-Mead descent.

High friction from a stiff polymer using microfiber arrays.

It is demonstrated that high-friction properties similar to rubberlike materials can be obtained using microfiber arrays constructed from a stiff thermoplastic (polypropylene, 1 GPa) using polypropylene's higher interfacial shear strength.

Towards friction and adhesion from high modulus microfiber arrays

Unlike traditional pressure sensitive adhesives, the natural setal arrays of gecko lizards achieve dry adhesion with stiff, keratinous material. This remarkable property has inspired a new class of…

Cell settling effects on a thermal inkjet bioprinter

The results show that cell output initially followed the predicted increasing trend, but then peaked and decreased, and provided guidance for modifications to the printing process to ensure consistent printing of cells.

Building off-the-shelf tissue-engineered composites

In 2003, the concept of combining rapid prototyping techniques with tissue engineering technologies to facilitate precision development of heterogeneous complex tissue-test systems, i.e. systems to be used for drug discovery and the study of cellular behaviour, biomedical devices and progression of disease was disclosed.
