Single sheet separation method from piled fabrics by roller hand mechanism and separation success judgement method by Keisuke MANABE, Xin TONG, Yasumichi AIYAMA

“…In order to automate the work in a garment factory, a method of single sheet separation from piled fabric is required. In this study, we developed a method of single sheet separation from piled fabrics by a roller hand mechanism with a rotating mechanism added to the tip of a robot hand. …”

Robotic action/observation planning for playing yamakuzushi based on human motion by Tomohiro MOTODA, Weiwei WAN, Kensuke HARADA

“…In this paper, we propose a novel robotic action/observation planning method for playing“ Yamakuzushi ”game which is a Japanese board game selecting one Shogi piece from the randomly stacked pile and sliding it off the board. In our proposed method, we first select one of the pieces from the pile by referring a human operation characteristics. …”

Study on the difference of separation performance of an overlap-type and a pressing-type sheet separation mechanisms by Kazushi YOSHIDA, Toshifumi MITSUYAMA, Mizuki KAII

“…As a result, we found that, in the overlap-type sheet separation mechanism, when the piled paper sheets move between the feed-roller and the gate roller, a slippage caused by the resistance force that is proportional to the number of the piled sheet occurs between the piled paper sheet, and this slippage is the factor that is superior to the pressing-type sheet separation mechanism.…”

Two-stage robotic picking for randomly stacked objects with recognition difficulty by Yuya SATO, Kensuke HARADA, Nobuchika SAKATA, Weiwei WAN, Ixchel G. RAMIREZ-ALPIZAR

“…For such objects, our method first roughly grasps some of the objects from the pile without using the visual information and roughly place them onto a working table. …”

Effect of strain rate on serrated load of indentation in Al-Mg alloy by Tsuyoshi KAMI, Hiroyuki YAMADA, Nagahisa OGASAWARA

“…However, the hardness can be influenced by pile-up of material after indentation. The purpose of this study was to relate the indentation strain rate with the uniaxial strain rate through serration behavior. …”

Experimental analysis of the clustering behavior of spherical bubbles rising along an inclined flat plate by Toshiyuki OGASAWARA, Shota SHIRAI, Hiroyuki TAKAHIRA

“…When the number density of bubbles becomes higher and the rising velocity along an inclined flat plate becomes slower, the bubbles tend to be horizontally arranged in line and such arrangements pile up to the bubble cluster. The spatial distribution of bubbles has been evaluated by the pair distribution function, which shows the frequent existence of side-by-side bubble pairs and the preferential accumulation within the range of about 8d (d is the average bubble diameter) corresponding to the size of the typical bubble cluster. …”

Calculation approach of optimum cutting surfaces of extra length of pipe spools by Takashi KITAHARA, Yuichi YAMAMOTO, Munechika MASAKI, Yasutaka TAGAWA

“…At this time, a little amount of installation error which derives from welding distortion and manufacturing error of each spool is piled up on the piping route. Thus, the last pipe spools which are connected between the terminal equipment and a next-to-last pipe spools, have extra length parts at both ends to adjust the installation error, and are cut at appropriate position at the construction sites. …”
