Programmable vector elds are an abstraction to represent a new class of devices for distributed, non-prehensile manipulation for applications in parts feeding, sorting, positioning, and assembly. Unlike robot grippers, conveyor belts, or vibratory bowl feeders, these devices generate force vector elds in which the parts move until they may reach a stable equilibrium pose. Recent research in the...

Questions surrounding the origin and early evolution of primates continue to be the subject of debate. Though anatomy of the skull and inferred dietary shifts are often the focus, detailed studies of postcrania and inferred locomotor capabilities can also provide crucial data that advance understanding of transitions in early primate evolution. In particular, the hand skeleton includes characte...

Synopsis Previous studies have focused on documenting shape variation in the caudal vertebrae chameleons underlying prehensile tail function. The goal of this study was to test impact function using multibody dynamic analysis (MDA). First, observations from dissections and 3D reconstructions generated contrast-enhanced µCT scans were used document regional arrangement muscles along antero-poste...

the rings considered in this article are commutative with identity $1neq 0$. by a proper ideal of a ring $r$,  we mean an ideal $i$ of $r$ such that $ineq r$.  we say that a proper ideal $i$ of a ring $r$ is a  maximal non-prime ideal if $i$ is not a prime ideal of $r$ but any proper ideal $a$ of $r$ with $ isubseteq a$ and $ineq a$ is a prime ideal. that is, among all the proper ideals of $r$,...

Action goals have often been investigated in previous studies within a single action. However, most of the manual actions (such as prehension) are not restricted to action towards object but can involve multiple follow-up achieve further purpose. The coordination initial (grip posture) and final (task purpose) such complex is still fully understood. In present experiment, neural mechanisms unde...

We argue that the direct experimental approaches to elucidate the architecture of higher brains may benefit from insights gained from exploring the possibilities and limits of artificial control architectures for robot systems. We present some of our recent work that has been motivated by that view and that is centered around the study of various aspects of hand actions since these are intimate...
