TALK AT HUST
Prof. Tatsuo Arai, Osaka University
Topic 1: Micro Robotics and Its Application in Bio Assembler
报告时间：2015年1月19日9:00
报告地点：南一楼中311室
Our micro robotics covers dexterous high speed micro manipulation, micro assembly, cell characterization, and 3D cellular system construction. The basic idea is to devise and to utilize dexterous two finger micro hands, and to achieve total micro manipulation system with high speed vision and interfaces for bio applications. Our system is multi-scalable and can manipulate micro object with the size ranging from one to hundreds micron meters seamlessly. our constant system improvement and refinement have achieved wide range of workspace with real time 3D information, simple finger setting-up procedure, fine force sensing capability as well as automated calibration, automated picking-and-placing, etc. Based on these activities and our collaboration experiences we launched 5 year national project on “Bio Assembler” in 2011, whose target is a challenge of constructing 3D cellular system,(tissues) in vitro.
http://www-arailab.sys.es.osaka-u.ac.jp/web/english/index.php The major topics are high speed cell characterization & sorting, 3D cellular system construction, and cell functionalization analysis. Currently 21 research groups join the consortium and work together in the internal and/or external research collaborations.

Mobile manipulation robot is one of the promising devices applicable in the dependable service use. We proposed the Limb Mechanism concept where a robot has limbs that can be used both for manipulation and for locomotion, then the robot comes expectedly to compact. Base on this concept we have been developing mobile robot “ASTERISK” that can walk and execute manipulation tasks in complicated environment with the aim of monitoring and inspection work. Another aspect is to use humanoid for daily life support. The HRP2 was applied to pushing wheelchair with on-riding person, where the robot was required to exert good enough force to push as well as to keep its stable walks. The robust and simple control strategies required to push heavy object such as wheelchair with on-riding human were proposed. The last issue is human robot interaction. While the service robot could have any essential physical safety means, users cannot always feel comfortableness. Even users understand the robot would not hurt them, they may be scared by and feel anxiety against it. In this sense the ‘mental safety’ of robot is another issue concerned for service applications. We have been engaged in the psychological evaluation of humanoid and proposed an evaluation scale using huge amount of subject data.
Tatsuo ARAI was born in 1952 in Tokyo. He received B.S. M.S. and PhD degrees from the University of Tokyo in 1975, 1977, and 86 respectively. He joined the Mechanical Engineering Laboratory, AIST in 1977, and was engaged in research and development of new arm design and control, mobile robot, teleoperation, and micro robotics. He stayed at MIT as a visiting scientist in 1986-1987. He moved to Osaka University in 1997 and since then he has been a full professor at the Department of Systems Innovation, Graduate School of Engineering Science. His current research topics are mechanism design including parallel mechanisms, legged working robot, micro robotics for bio application, humanoid robot, and robot impression evaluation. He is currently leading the project on Bio Assembler, the MEXT Grant-in-Aid for Scientific Research on Innovative Areas Program since 2011. He has published more than 400 papers listed on http://www-arailab.sys.es.osaka-u.ac.jp/index.php?option=com_content&view=article&id=56&Itemid=57&lang=en
He is a member of IEEE, IAARC, RSJ, JSME, SICE, and a president of the Council for Construction Robot Research.
