In recent years, research and development on micro fluid systems has become active in the fields of chemical technology and biotechnology. For the realization of these micro fluid systems, micro fluid devices such as micro-valves and micro pumps are very important. This paper reports the fabrication and experimental evaluation of several micro one-way valves. The valves are fabricated through a micro molding process, which makes the fabrication process simple and suitable for mass production. The experimental results indicate that the developed valve has great performance with a normal flow rate of 130.2 ml/min and a leak flow of 2.2 ml/min. The normal flow rate is 1.4 times higher than that of the previous model.

This article describes the improvement of a pneumatic nutation motor. Pneumatic nutation motors that are driven by diaphragm are expected to have bigger torque. In this report, refined design of the diaphragm is discussed. First, several different shapes of diaphragms are proposed and analyzed with nonlinear FEM. Second, a “bellows type” diaphragm is fabricated and built in the motor. Holding fixture for the diaphragm is also refined to improve its performance. Finally, torques of the new model and conventional model are compared,resulting in that the new model generates the torque 20 percent higher than that of the conventional model at any air pressure.

The purpose of my work is to develop a new soft actuator with magnetic intelligent fluids such as a magnetic fluid and a magneto-rheological fluid for flexible walking robots. For this purpose, the authors have produced two types of soft magnetic materials. One is called the magnetic fluid rubber that consists of an isoparaffin-based magnetic fluid and elastic silicone rubber. The other is called the magneto-rheological fluid rubber that consists of a polyalphaolefin-based magneto-rheological fluid and elastic silicone rubber. We have developed four types of cylindrical soft actuators using proposed soft magnetic materials. An experimental system was constructed and a response test was made using it. A Laser displacement sensor was employed to find the relationships between the magnetic flux density and the displacement of soft actuator. The experiment showed that the responsibility of soft actuator with the magnetic fluid rubber indicated the best performance. In addition, we operated four electromagnetic coils to control the direction and the displacement of soft actuator. As a result, we have succeeded in moving the tip of soft actuator like drawing a circle. We represented a first possible step towards the development of soft actuator with magnetic functional fluids for flexible walking robots.
