In this study, a next-generation Kansei-equipment agricultural robot is proposed and focuses jn controlling the robot through body language. Kansei agri-robots are defined as agricultural robots equiped with Kansei communication and robotic Functions. Kansei communication is defined as «two-way communication between humans and robots, or other machines, that supplements or supersedes traditional one-way (human-to-machine) input and operation».

Carbon nanotubes (CNT) are remarkable materials with a simple and inert molecular structure that gives rise to a range of potentially valuable physical and electronic properties, including high aspect ratio, high mechanical strength and excellent electrical con-ductivity. This review summarizes recent research on the application of CNT-based materials to study and control cells of the nervous system. It includes the use of CNT as cell culture substrates, to create pat-terned surfaces and to study cell–matrix interactions. It also summarizes recent investigations of CNT to-xicity, particularly as related to neural cells. The application of CNT-based materials to directing the differentiation of progenitor and stem cells toward neural lineages is also discussed. The emphasis is on how CNT surface chemistry and nanotopography can be altered, and how such changes can affect neural cell function. This knowledge can be applied to creating improved neural interfaces and devices, as well as pro-viding new approaches to neural tissue engineering and regeneration.

A wearable action-assist device includes a biosignal detection unit detecting a biosignal from a wearer, an action-assist wearing tool having a drive source supplying a torque acting on the wearer around each joint of the wearer as an axis of rotation, a control unit controlling the drive source to generate the torque according to the detected biosignal, a drive torque estimation unit estimating a drive torque generated by the drive source, a joint-angle detecting unit detecting an angular displacement of the joint, and a parameter identification unit identifying kinetics parameters concerned by substituting the estimated drive torque and the detected angular displacement into an equation of motion of an entire system including kinetics parameters intrinsic to the wearer. The control unit is configured to control the drive source according to a predetermined control method based on the equation of motion into which the identified parameters are substituted.

To suppress human tremor, researchers in this field devote themselves to develop a wearable tremor-suppression orthosis, but one of the most important difficulties lies in how to obtain real-time filtering and estimation of the tremor from the input signal. In this article, Fourier Linear Combiner(FLC) and a series of derived algorithms are analyzed first, then an improved algorithm–Shifted Band-limited Multiple Fourier Linear Combiner(SBMFLC) is proposed. Simulation results make it clear that the improved algorithm is more adaptive and accurate to the tremor suppression.
