Underwater microrobots are in urgent demand for applications such as pollution detection and video mapping in limited space. Compact structure, multi-functionality, and flexibility are normally considered incompatible characteristics for underwater microrobots. Nevertheless, to accomplish our objectives, we designed a novel inchworm-inspired biomimetic locomotion prototype with ionic polymer metal...
This paper proposed a new biomimetic underwater microrobot using shape memory actuator (SMA). It moved like a jellyfish while floating and sinking, and had two pectoral fins to implement the swimming motion like a butterfly. To achieve a larger volume change, we designed the body as a triangular prism. Then we modelled the characteristics of the body and calculated its floating speed. Also, we used...
In the field of underwater monitoring for applications such as pollution detection and video mapping in limited space, underwater microrobots are urgently demanded. Compact structure, multi-functionality, and flexibility are normally considered as incompatible characteristics for underwater microrobots. To implement these purposes, we have developed several types of microrobots with both compact structure...
Compact structure, multifunction, and flexibility are normally considered as incompatible characteristics for legged microrobots. Most robots focused on complex structure of multi-joint legs to attain the multifunction and flexibility, while others had poor flexibility for miniaturization. In the field of underwater monitoring for applications such as pollution detection and video mapping in limited...
Nowadays, studies of the biomimetic microrobots with multi DOF that can walk and swim smoothly in water or aqueous medium have been hot topics in the field of underwater monitoring operations, including pollution detection, video mapping and other tasks. Actuator materials of all types are of interest for any application where space is limited. This constraint certainly applies to the small-scale...
Biomimetic microrobot with multi DOF that can walk smoothly in water or aqueous medium has urgently been demanded in the medical field and industry application. For this kind of microrobot, some characteristics are needed, such as simple and compact structure and efficient locomotion. Then special actuator materials are manufactured to realize these requests. One of this kind of materials is IPMC...
Biomimetic microrobot and micro biped robot with multi DOF that can swim smoothly in water or aqueous medium has urgently been demanded in the medical field and industry application. The IPMC (Ionic Polymer Metal Composite) has a good response and soft characteristic. Also it can generate large bending motions under a low driving voltage (about 1 V). In order to resolve the problems of asymmetry in...
In the medical field and industry application, fishlike microrobot and micro biped robot with multi DOF that can swim smoothly in water or aqueous medium has urgently been demanded. And IPMC (ionic polymer metal composite) can generate large bending motions under a low driving voltage (about 1 V), and it has a good response and soft characteristic. In this paper, we have developed a new jellyfish...
