Inspired by kangaroo's locomotion, we report on developing a kangaroo-style hopping robot. Unlike bipeds, quadrupeds, or hexapods which alternate the legs for forward locomotion, the kangaroo uses both legs synchronously and generates the forward locomotion by continuous hopping behavior, and the tail actively balances the unwanted angular momentum generated by the leg motion. In this work, we generate the Center of Mass (CoM) locomotion of the robot based on the reduced-order Rolling Spring Loaded Inverted Pendulum (R-SLIP) model, for matching the dynamic behavior of the empirical robot legs. In order to compensate the possible body pitch variation, the robot is equipped with an active tail for pitch variation compensation, emulating the balance mechanism of a kangaroo. The robot is empirically built, and various design issues and strategies are addressed. Finally, the experimental evaluation is executed to validate the performance of the kangaroo-style robot with hopping locomotion.

The process of solving information management's problems is a hardheaded thinking in decision-making. Although many scholars proposed related theories and suggestions, these are so conceptual and one-sided that cannot be a systematic application. As the result, enterprises are always disorganized when solving problems. The reason is that enterprises can't clearly utilize systematic processes in an idea of problem-solving. Therefore, this research (1) uses Information Processing Theory to control the concept of problem-solving; (2) builds "Systematic Information Problem-Solving Process" with Pyramid Principle; (3) verifies and modifies the systematic process through qualitative methods; (4) refers a case study to explain the results of software development from a bio-technology company in Taiwan and to confirm the substantive. It is believed that the research not only shows a new perspective in academia, but gives enterprises a systematic process to improve the ability of solving problems.

Previous studies have shown that the pseudo-bipolar design of the bi-cell is composed of two outside anodes and two inside cathodes that share a common PZT vibrating device used to pump the airflow. The bi-cell is operated by three modes of PZT-actuating process as pump mode (Pc > Pout > Pin), supply mode (Pout > Pin > Pc), and transition mode (Pout > Pc > Pin). In this study, a single module of piezoelectric PEMFC honey comb composed of 6 bi-cells on each inside wall of the honey comb has been developed to deliver the net power output 7.5W. The hydrogen storage tank is located in the middle duct of one honey comb with hydrogen supply valves and pipelines. Furthermore, for the required power output, the honey comb stack can be designed as erect-stack or planar-stack by assembling different number modules. Comparing with other polygons, the stronger honey comb stack can be designed to fit in the limited space and coupled with the fuel supply system or other power output system, for example, LED lights.

Based on the inspiration of the kangaroo's locomotion, we report on the development of a kangaroo robot with dynamic locomotion. Not like bipeds, quadrupeds, or hexapods which use multi legs for locomotion, the kangaroo usually moves two legs in phase, which resides in a very unique class of locomotion as the monopod. Though special, the research about its continuous forward locomotion is very limited. In this work, the center of mass locomotion of the robot is designed to move according to the spring loaded inverted pendulum (SLIP) with rolling contact, based on the fact that the SLIP is widely used as the model for legged animal's dynamic locomotion. To compensate the possible body pitch variation, the robot is equipped with an active tail for pitch variation compensation, like the kangaroo does. The robot is empirically built, and various design issues and strategies are addressed. Finally, the experimental evaluation is executed to validate the performance of the design of the robot with dynamic locomotion.
