In this paper, we propose a robotic model of a casterboard, which is a commercial variant of skateboards with twistable footplates and passive inclined caster wheels. We then derive its mathematical model in the form of nonlinear state equation; this system is of much interest from both mechanical and control points of view as a new challenging example of nonholonomic mechanics. Based on an observation in the preceding works concerning locomotion control for nonholonomic systems, we propose a locomotion control method with sinusoidal periodic control to realize forwarding and turning locomotion. The proposed idea is examined by simulations and physical experiments using the prototype robot developed by the authors. Moreover, we also examine influence of the parameters in sinusoidal reference signals on the robot's behavior.

A design method of state estimation observer under outliers and data-lost environment is proposed in this paper. In networked control systems, the data-lost is one of the most important topic for solving. When data-lost occurred, the output data for the control system is disappeared. The data-lost is significant problems if we want to use state feedback. To overcome negative impact by outliers and data-lost, we propose a method to disappear negative impact by outliers and data-lost using median information. The effectiveness of the proposed observer is evaluated by numerical examples.

Although animal-assisted activity is attracting attention as one of mental health measures, it has many problems in its implementation. We compared stress relief effects in short-term interaction of robot-assisted activity and stuffed animal-assisted activity, which are complementing activities for animal-assisted activity. We confirmed that psychological stress relief effects, especially reducing tension, depression, and confusion and improving vigor, obtained by robot-assisted activity are significantly higher than that obtained by stuffed animal-assisted activity. On the other hand, no significant difference could be confirmed in physiological stress relief effects. Although negative feelings of unsatisfactory due to lack of reactions decreased psychological stress relief effects, some kind of interaction caused by softness were suppressed decreasing physiological stress relief effects combination with physiological stress relief effects by contact with soft things. These are assumed to be factors that results of psychological and physiological evaluations are different.

This paper describes the properties of proprioceptive sensations induced by an asymmetric vibration using a vibration speaker-type non-grounded haptic interface. We confirm that the vibration speaker generates a perceived force that pulls or pushes a user's hand in a particular direction when an asymmetric amplitude sound signal that is generated by inverting a part of a sine wave is input. We conducted 5 psychophysical experiments and evaluated the subjects' physical properties in order to apply this phenomenon for a variety of applications. As a result, we confirmed that the vibration speaker was able to control both the direction and magnitude of the reaction force by changing the input signal.
