In this paper we describe effects of human interactions with a pet-type robot, especially AIBO. First, design concept for AIBO based on how to increase its "lifelike" appearance. By introducing statistical results marketing, and experiments involving human-robot using AIBO, show that robot activates emotions effectively. Furthermore, the demonstrate helps in human-human communication. We discuss phenomena interaction attempt explain why happened.

This communication presents preliminary results of the first attempt to monitor rice crop growth from space transplanting harvesting with an active microwave instrument using ERS-1 C-band SAR.

A series of 5,7-disubstituted 1-cyclopropyl-6,8-difluoro-4(1H)-oxoquinoline-3-carboxylic acids (10-36) were prepared; the C-5 substituent in these compounds comprised halo, hydroxy, mercapto, and amino groups C-7 functional group included variously substituted piperazines. In vitro antibacterial screening results indicated that was optimal among substituents. combination 3,5-dimethylpiperazinyl appendage this conferred best overall property with lack adverse drug interactions. Compound 36k...

An evolutionary algorithm is used to evolve gaits with the Sony entertainment robot, AIBO. All processing handled by robot's on-board computer individuals evaluated using hardware. By sculpting experimental environment, we increase robustness different surface types and AIBOs. Evolved are faster than those created hand. Using this technique a gait in consumer version of

A humanoid robot that can go up and down stairs, crawl underneath obstacles or simply walk around requires reliable perceptual capabilities for obtaining accurate useful information about its surroundings. In this work we present a system generating three-dimensional (3D) environment maps from data taken by stereo vision. At the core is method precise segmentation of range into planar segments based on algorithm scan-line grouping extended to cope with noise dynamics off-line experiments...

The annealing behavior of poly(l-lactic acid) (PLLA) and poly(d-lactic (PDLA) single crystals was investigated in order to reveal the mechanism chain diffusion their solid states, below melting points. structural changes sedimented single-crystal mats on continuous heating were followed real time by synchrotron small-angle X-ray scattering (SAXS) wide-angle diffraction (WAXD) measurements. crystal homopolymer showed a discontinuous thickening at an temperature each point. experimental...

Abstract The hydrogen bond is undoubtedly one of the most important non-covalent interactions. Among several types bonds, CH–π interaction a relatively new notion that being recognised in chemistry and biology. Although conventional bonds share common features such as directionality, this weak has played secondary role molecular recognition. In study, we have devised host–guest complex assembled solely by bonds. Multivalent interactions bowl-shaped hydrocarbon with its peripheral atoms are...

Bin picking is still a challenge in robotics, as patent recent robot competitions. These competitions are an excellent platform for technology comparisons since some participants may use state-of-the-art technologies, while others conventional ones. Nevertheless, even though points awarded or subtracted based on the performance frame of competition rules, final score does not directly reflect suitability technology. Therefore, it difficult to understand which technologies and their...

Abstract Aromaticity has been a central concept in chemistry since the discovery of benzene 19th century and impacted science delocalized π-electron systems. The aromaticity conventional aromatic compounds usually originates from electron delocalization through single ring that consists π-symmetric orbitals. Although double aromaticity, i.e. composed two circularly orbitals, theoretically predicted for over 20 years, bench-stable compound is not well explored by experiment. Here we report...
