Computing Parallel-Jaw Grips

In this paper we propose a new model for gripping parts with an industrial parallel-jaw gripper. In contrast to many previous models, we use two grip points and define candidate grips that are resistant to slipping and torque about the part’s center of mass. These grips must also be accessible and robust to perturbations in part position. We give an O(n) algorithm for computing and ranking O(n)...

Why pens have rubbery grips.

The process by which human fingers gives rise to stable contacts with smooth, hard objects is surprisingly slow. Using high-resolution imaging, we found that, when pressed against glass, the actual contact made by finger pad ridges evolved over time following a first-order kinetics relationship. This evolution was the result of a two-stage coalescence process of microscopic junctions made betwe...

Getting to grips with ammonium

A fluorescent sensor that can monitor levels of extracellular ammonium has been made by using a fused green fluorescent protein to detect conformational changes in ammonium transport proteins.

Coming to Grips with Security

I T security has evolved dramatically over the last few decades. Initially, it consisted of password management and basic network security controls. However, as enterprises have come to depend on IT for every aspect of daily operations, the need for security has transcended the datacenter and now is woven through all aspects of IT operations. The product space has become more complicated as org...
