As a novel biologically inspired underwater vehicle, robotic manta ray (RoMan-II) has been developed for potential marine applications. Manta can perform diversified locomotion patterns in water by manipulating two wide tins. These motion have implemented on the fish robot, including swimming flapping fins, turning modulating phase relations of and online transition different patterns. The movements are achieved using model artificial central pattern generators (CPGs) constructed with...
In recent years, betavoltaic batteries have become an ideal power source for micro electromechanical systems. Betavoltaic battery is a device that converts the decay energy of beta emitting radioisotope sources into electrical using transducers. They advantages high density, long service life, strong anti-interference ability, small size, light weight, easy miniaturization and integration, thus it has research hotspot in field energy. However, to date, low conversion efficiencies as well...
We measured kinetic energies of the fragment ions argon dimers multiply ionized by low-energy Ar(9+) collisions. For (Ar2)(4+) dissociation, asymmetric channel (Ar(3+) + Ar(+)) yield is found unexpectedly higher than symmetric (Ar(2+) Ar(2+)) in contrast with previous observation for covalent molecules or clusters. dissociation (Ar2)(2+)→Ar(+) Ar(+), two well-separated peaks were observed, clearly evidencing that direct Coulombic and radiative charge transfer followed ionic alternatively...

We provide the experimental evidence that single electron capture process in slow collisions between ${\mathrm{O}}^{3+}$ ions and neon dimer targets leads to an unexpected production of low-energy electrons. This results from interatomic Coulombic decay process, subsequent inner-shell one site dimer. Although pure one-electron inner shell is expected be negligible low collision energy regime investigated here, due this overtakes by 1 order magnitude emission Auger electrons scattered...
Abstract This paper is dedicated to the implementation of biological fish swimming motion onto biomimetic robots. By learning from different species fish, mechanism design and motor control machines could be shaped in forms. In general, they can grouped into two major forms, an engineering viewpoint: serial open-chain parallel design. The gait planning on both forms then performed based well-established theory swimming. using associated kinematics equations, generic solution for multi-link...
