Multifunctional materials and devices found in nature serve as inspiration for advanced synthetic materials, structures, and robotics. Here, we elucidate the structural mechanics and unusual deformation mechanisms discovered in seahorses that provide them prehension and protection against predators. The seahorse tail is composed of subdermal bony plates arranged in articulating ring-like segmen...

Median nerve (MN) compression is a recognized component of carpal tunnel syndrome (CTS). In order to document compressive changes in the MN during hand activity, the carpal tunnel was imaged with neuromuscular ultrasound (NMUS). Ten patients with CTS and five normal controls underwent NMUS of the MN at rest and during dynamic stress testing (DST). DST maneuvers involve sustained isometric flexi...

To achieve human-level object manipulation capability, a robot must be able to handle objects not only with prehensile manipulation, such as pick-and-place, but also nonprehensile manipulation. study we studied robotic batting, primitive form of Batting is challenging research area because it requires sophisticated and fast moving considerable improvement. In this paper, designed batting system...

The Dual Visuomotor Channel Theory proposes that manual prehension consists of two temporally integrated movements, each subserved by distinct visuomotor pathways in occipitoparietofrontal cortex. The Reach is mediated by a dorsomedial pathway and transports the hand in relation to the target's extrinsic properties (i.e., location and orientation). The Grasp is mediated by a dorsolateral pathwa...

A new genus, Thaicypris gen. nov., in the tribe Herpetocypridini Kaufmann, 1900 of subfamily Herpetocypridinae is established to accommodate a species from Thailand. The present contribution deals with description genus and species, panhai et sp. which mainly characterized by distinctive raised, inwardly displaced selvage at postero-ventral part right valve (RV) that not parallel margin, absenc...

Intrinsically disordered regions within proteins are critical elements in many biomolecular interactions and signaling pathways. Antibacterial toxins of the colicin family, which could provide new antibiotic functions against resistant bacteria, contain disordered N-terminal translocation domains (T-domains) that are essential for receptor binding and the penetration of the Escherichia coli out...

Object manipulation is a complex task for robots. It often implies a compromise between the degrees-of-freedom of hand and its fingers have (dexterity) and its cost and complexity in terms of control. One strategy to increase the dexterity of robotic hands with low dexterity is called extrinsic manipulation and its principle is to exploit additional accelerations on the object caused by the eff...
