본 논문에서는 이동로봇에 사용되는 저가형 다중 센서를 이용하여 로봇의 작업환경을 인지할 수 있는 다중 센서 시스템을 개발하고, 이에 따른 이동로봇의 사용자 인터페이스를 개발함으로써 원격지에서 이동로봇을 조종하는데 주변 환경에 적합한 센서를 선택하고, 선택된 센서의 정보를 사용자 인터페이스 화면에 표시하는 '자동 절환' 기능을 추가함으로써 로봇주위의 환경을 보다 효과적으로 파악할 수 있는 인터페이스를 구현하였다. 실험에 사용된 저가용 센서는 초음파, Position sensing detector, 저가형 CMOS 카메라 모듈을 사용하였다.

SS2-2, a hypernodulating soybean mutant was isolated by EMS mutagenesis from Sinpaldalkong 2. This auto-regulation mutant showed greater number of nodules and smaller plant size than its wild type Sinpaldalkong 2. SSR markers were used to identify DNA variation at SSR loci from different soybean LG. The only SSR marker that detected a length polymorphism between SS2-2 and its wild type ancestor was Satt294 on LG C1 instead of LG H, locating a hypernodulating gene. Sequencing data of flanking Satt294 indicated that the size variation was due to extra stretch of TTA repeats of the SSR motif in SS2-2, along with $A\longrightarrow$G transversion. In spite of phenotypic differences between the wild type and its hypernodulating mutants, genomic DNA poly-morphisms at microsatellite loci could not control regulation of nodule formation. The cDNA-AFLP method was applied to compare differential display of cDNA between Sinpaldalkong 2 and SS2-2. After isolation and sequence comparison with many AELP fragments, several interesting genes were identified. Northern blot analysis, immunolocalization and/or the yeast two-hybrid system with these genes might provide information on regulation of nodule development in SS2-2.
