The demand for monitoring from high points is increasing to support remote control and accurate monitoring. Unmanned ground vehicles with long arms are used to achieve long-term and accurate monitoring. The use of convex steel tapes is effective for achieving both high strength and lightness of the arm, which prevents the robot from collapsing or the arm from falling off. However, the previously proposed...
In recent years, the research of micro pumps are actively conducted with the rise of MEMS (Micro Electro Mechanical Systems) technology. In this study the authors have realized the micro pump driven by conducting polymer soft actuator that perform open/close movement based on polypyrrole and measured their performance. It could adjust flow rates in the approximately 2-83 [mul/min] and easily change...
This paper proposed a small and light actuator based on an easy ON-OFF control to movement walking robot. We named a flexible, flat plate to FFP actuator as an actuator of a flexible locomotion robot. The FFP actuator is a versatile actuator that mechanically obtains flexible displacement by combining functional materials like the shape-memory alloy with a simple lamina structure lightly not broken...
This paper presents an innovative variable-wing mechanism based on flapping motion of birds. The main feature of the mechanism proposed in this paper is to realize the complicated flapping motion of birds such as flapping, spanning, lead-lagging and feathering by using only a single actuator. We show the utility of the new variable-wing mechanism by comparing the motion generated by the new mechanism...
A problem of stabilization about uncertain networked control systems (NCSs) with random but bounded delays is discussed in this paper. By using augmented state-space method, this class of problem can be modeled as discrete-time jump linear system governed by a finite-state Markov chains. A new switched model based on probability is proposed to research problems of reliable control when actuators become...
This paper describes an application of flexible flat plate (FFP) actuators (consisting of shape memory alloy (SMA) and polyethylene plate) to some legged locomotion robots. A key feature is that the legged locomotion robots developed in this paper have no joints. In other words, the FFP actuators that become the robot legs (links) can directly generate power by their deflections. In addition, the...
