Precise assembly of ring part with optimized hollowed finger

We deal with a technical issue of assembling a ring part into a shaft part with the clearance of several micrometers by using a robotic manipulator. This issue is difficult because of deformation of a ring part compared with peg-in-hole assembly. We propose a precise assembly method of a ring part with finger shape to solve this issue. We also propose a method to decide design ...

State of the art: micro-nanorobotic manipulation in single cell analysis

Single cell analysis is an essential research approach to reveal the secret of life. At such a small scale, it puts forward higher demand on the accuracy of the cell manipulation system. This paper reviews the state of the art of micro-nanorobotic manipulation in single cell analysis. First, the key applications of the micro-nanorobotic manipulation system in single cell analysis ...

Consensus-Making Algorithms for Cognitive Sharing of Object in Multi-Robot Systems

Background Visual recognition in multi-robot systems is afflicted with a peculiar problem that observations made from different viewpoints present different perspectives. Hence, realizing cognitive sharing of the object among robots in an unconstructed environment has become challenging. To cope with these issues, we have proposed the Hierarchical Invariants Perception Model (HIPM) ...

Solid variant of aneurysmal bone cyst in the tibia treated with simple curettage without bone graft: a case report

The solid variant of aneurysmal bone cyst (solid ABC) is rarely encountered in long bones and appropriate treatment for this disease remains unclear. We experienced a 13-year-old boy suffering from pain in his left knee caused by solid ABC. Simple curettage of the bone lesion without any adjuvant therapy and a bone graft gave immediate pain relief. Histological examination of the ...

A Novel Single Virus Infection System Reveals That Influenza Virus Preferentially Infects Cells in G1 Phase

Background Influenza virus attaches to sialic acid residues on the surface of host cells via the hemagglutinin (HA), a glycoprotein expressed on the viral envelope, and enters into the cytoplasm by receptor-mediated endocytosis. The viral genome is released and transported in to the nucleus, where transcription and replication take place. However, cellular factors affecting the ...
