Even when a robot is small andlightweight, it can assist human when the assist fitsthe natural human movements. By modeling thecharacteristics of natural human movements, we aimto develop safe and effective life support robots.Outlook for students after graduationStudents willlearn safety, which is an essentialelement of manufacturing, and biomechanics andstatistical analysis, which are also essentialforevaluating the usability of products. I expect thatstudents will play an important role in the industries.Recently, graduates have gone on to manufacturing,infrastructure, and other companies.Associate ProfessorAKIYAMA YasuhiroAssociate ProfessorUMEDACHI TakuyaDepartment of Machinery and RoboticsFunctional Machineryand MechanicsDepartment of Machinery and RoboticsFunctional Machineryand MechanicsOutlook for researchOutlook for students after graduationHe received the Ph.D. degree inengineering from the University ofTokyo in 2011. Since 2016, he was anassistant professor of Nagoya University.Currently, he has been an associateprofessor of Shinshu university since2022. His main research areas aremechanicalhuman-robotsafety,interaction, and biomechanics.Associate Professor Umedachireceived a Ph.D.in TohokuUniversity in 2009. He workedat Tufts University in the US asJSPS fellow for 3 years from2012. He worked attheUniversity of Tokyo as aLecture from 2016 to 2019.-Development of robots for use in human living and wild environments (e.g.,caterpillar-like robots for monitoring electric wires, earthworm-like robots formonitoring soil). -Digital fabrication and design methods for general-purpose soft-bodied robots by rapid prototyping with drastic reductions in assembly costs. -Creation of new academic and industrial fields that propose such soft-bodiedrobots in unprecedentedly complex environments. -Further understanding ofbiological systems by using the soft-bodied robots as a platform: Designing `life asit could be’ because we can design the body structure and control systems freely.Through our research activities, students can learn how to develop an algorithmicmechanical design (automatic generation of shapes using programs), novelfabrication ways using rapid prototyping (3D printers and laser cutters), robotics,and system thinking through the robot design. The skills are required in a widerange of fields (e.g., the automobile industry and IT/IoT companies). Our graduatesare active as engineers in semiconductors, electronics, and industrial machinery.Our laboratory's focus is how to design intelligent behavior of robotsemerged from the mechanical softness. Living systems from primitive ones tohomo sapience are made from three-dimensionally deformable materialssuch as muscles, tendons, and skin tissues. A vast number of neurons are notnecessarily required to control the soft bodies. Primitive organisms, e.g.,caterpillars and amoeba, control the almost infinite degree of freedom theirbodies with distributed information processing systems such as a smallnumber of neurons and biochemical reactions. Our laboratory considers"mechanical softness" to be an essential difference between machines andliving things. Inspired by these primitive living creatures, we are designing theintelligence of soft-bodied robots that can be realized by the mechanicalsoftness of textiles, fibers, and rubber-like materials. This academic fieldnamed soft robotics and proliferating in recent years.Development of various gait assist devicesFall experiment and fall simulationCaterpillar-inspired robot printed with 3D printing. By using both bending and compression deformations, faster, more diverse crawling locomotions are realized.Actuator and bending sensor film printed with Silver-nano inkCaterpillar-inspired crawling robot driven by Wireless Power Transfer SystemRobots used in the daily living environments should fit humanmovements. Inconsistency of motion between robot and humancompromises safety and convenience. It is also important thatthe robot is easy to use and does not impose a burden on theuser. To solve these problems, we are developing various robotsand devices and evaluating their safety and effectiveness. Thehuman experiment and simulation are valuable tools for thispurpose. Thus, we are also developing a simulation model tomimic the human natural movement.Safe and usable robot and device based on the human-centric designLet’s create bio-inspired resilient soft-bodied robots from textile and fibers!
