The Roller-Walk is one of methods for locomotion of walking robots. It requires only passive wheel(s) on each of legs, and periodic motions of legs generates driving force. Successful results were shown in quadruped robot, and some trials had also been carried out on biped robot. The biped roller-walk had a problem in following trajectories because its 'skate' tends to go straight while trajectory curves. This paper proposed one of successful method for biped roller-walk. The robot use a special type of trucks whose curvature can be changed only by inclining the body of the truck. The experiments showed effectiveness of our mechanism in roller-walk on straight, right turn, and left turn trajectories.

This article describes recent progress of surface plasmon related techniques for bio-application. The first part is concerning propagating surface plasmon resonance (SPR), where we discuss the complication of nano to micron scale inhomogeneous materials for characterization by the interfacial waves. The second part is concerning crystalline sheets composed of metallic nanoparticles (‘plasmonic nanosheet’). This nano-thickness sheet exhibits a unique optical property originating from the two dimensionally coupled localized SPR. The concept to use the plasmonic nanosheet for new biosensing devices is introduced.

Remote photocatalytic reaction of a Pt-modified TiO2 thin film was investigated by using Ag nanosheet as a marker. The Ag nanosheet is a two-dimensional crystalline film composed of myristate-capped silver nanoparticles (d = 5 nm), which has a strong localized plasmon absorption band at λmax = 470 nm. The Ag nanosheet on a 50 nm gold film was set on a measurement cell at 10 μm distance from the Pt-modified TiO2 film. Then the refractive index change of Ag nanosheet was real-time monitored by a surface plasmon resonance (SPR) technique under UV light irradiation (wavelength: 365 nm) from the back side of the TiO2 film. The plasmon resonance angle shifted to lower angle in consequence of the degradation of Ag nanosheet due to the remote photocatalytic reaction. We found the reaction was continued even after stopping UV irradiation, i.e., a chain reaction in Ag nanosheet was suggested. The chain reaction was influenced by N2 gas purge as well as the ligand exchange of myristate capping molecules to alkyl thiolate.
