Animals provide inspiration for developing soft machines in bionics, robotics research as well as potential applications. This paper presents an integrated development of locomotive soft robot platforms: starfish-inspired robots with multi-limb bodies actuated by shape memory alloys (SMAs). The designs of these robots were based on the biological specifications of the locomotion and water-vascular...
This paper introduces a digital multi-mode boost converter with wide range of input voltage for an energy recycling load system. The boost converter is controlled digitally with constant off- time/constant frequency hybrid pulse width modulation (PWM) control. Constant off-time control is to avoid the limit cycle oscillation and gain a high gain when the input voltage is far less than the output voltage...
This paper presents a starfish-like robot with bionic soft body, multi-motion inspired by live starfishes. The structural design principle is based on the biological investigation. The robot prototype is fabricated with help of 3D printing model. By the locomotion principle and control strategy, the soft starfish-like robot is able to fulfill in crawling on flat ground, climbing over viscous soil...
Mollusks have a strong ability adapting to environment, many researchers have developed some soft robots mimicking the mollusks movements, but these soft robots usually have only one locomotion mode, which cannot effectively take into account the movement efficiency and the environment adaptability simultaneously. In this paper, we present a novel soft robot with three locomotion modes which are rolling,...
Enabling business developers to create business applications greatly reduces development cost and increases business adaptiveness. However, lacking of an application framework that is amenable to business people makes it hard for business developers to create decent business applications. This paper presents such a business application framework that consists of application components primarily including...
A novel three-level (3L) bidirectional converter (BDC) is proposed in this paper. Compared with the traditional BDC, the inductor of the 3L BDC can be reduced significantly so that the dynamic response is greatly improved. Hence, the proposed converter is very suitable for fuel-cell/battery hybrid power systems. In addition, the voltage stress on the switch of the proposed converter is only half of...
