  • 자연계에 존재하는 생물체는 오랜 시간에 걸쳐 지구의 가혹한 환경에 적응하면서 다듬어져온 최적화된 작품이다. 이러한 동 식물의 생체 특징 모방은 기존 기술의 한계를 돌파하면서 가장 활발한 연구 분야로 자리 잡고 있다. 생체모방 로봇은 생체모방 기술의 한 분야로써 곤충, 새, 물고기, 그리고 여타 동물들을 연구해 생명체의 우수한 특성을 로봇기술에 접목함으로써 기존의 로봇 시스템이 극복하지 못했던 수많은 난제 해결에 도전중이다. 생체모방 로봇 기술의 최신 동향을 크게 세 줄기로 나누면 실용화, 생체분석법의 다양화, 모방대상의 다양화로 분류될 수 있다. 이 글에서는 이상에서 언급한 생체모방 로봇의 최신 동향에 대해서 소개한다.

  • 생체 모방 로봇은 생명체에서 영감을 얻어 새로운 로봇분야를 개척하고 기존의 로봇으로는 하기 힘들었던 한계점들을 극복하는데 목적이 있다. 이러한 생체 모방 로봇은 간단한 생물체의 형태 혹은 메커니즘의 모방으로부터 시작되어 바퀴가 갈 수 없었던 험지, 혹은 하수구, 좁은 통로에서 사용될 수 있는 로봇들을 개발하는 데 초점이 맞추어져 있었다. 이러한 로봇들의 예로써는 크게 이족 보행, 4족 보행, 다족 보행 로봇 등 생물체의 이동 메커니즘을 모방한 로봇들이 있다. 이러한 연구들은 기존 로봇에 사용되었던 재료, 제작 방법을 이용한 것이었다. 하지만 최근 생체 모방 로봇 기술은 새로운 접근 방법, 새로운 재료를 이용한 제작방법으로 기존의 로봇과는 다른 형태로 진화하고 있다. 이러한 기술은 경량화 기술, 초 소형화 기술, 3차원 프린팅 기술 그리고 소프트 물질을 이용한 제작 방법 등이 있다.

  • Covert Underwater Communication (CUC) signals should not be detected by other unintended users. Similar to the method used in Radio Frequency (RF), covert communication technique sending information underwater is designed in consideration of the characteristics of Low Probability of Detection (LPD) and Low Probability of Intercept (LPI). These conventional methods, however, are difficult to be used in the underwater communications because of the narrow frequency bandwidth. Unlike the conventional methods of reducing transmission power or increasing the modulation bandwidth, a method of mimicking the acoustic signal of an underwater mammal is being studied. The biomimetic underwater acoustic communication mainly mimics the click or whistle sound produced by dolphin or whale. This paper investigates biomimetic communication method and introduces research trends to understand the potential for the development of such biomimetic covert underwater acoustic communication and future research areas.

  • We present a pipeline monitoring system based on bio-memetic robot in this paper. A bio-memetic robot exploring pipelines measures temperature, humidity, and vibration. The principal function of pipeline monitoring robot for the exploring pipelines is to recognize the shape of pipelines. We use infrared distance sensor to recognize the shape of pipelines and potentiometer to measure the angle of motor mounting infrared distance sensor. For the shape recognition of pipelines, the number of detected pipelines is used during only one scanning of distance. Three fuzzy classifiers are used for the number of detected pipelines, and the classifying results are presented in this paper.

  • This study explores the organic form generation method, which reflects the evolving biomimetic approaches converging in fashion technology and considers the characteristics of the organic relationship between the body and the clothing to be represented in contemporary fashion. A literature review on biomimetic architecture and design-related theory and a case study on biomimetic fashion were both conducted. Images, articles, and data related to biomimicry fashion and clothing, including the increase in virtual fashion cases around 2020, were analyzed based on the literature review. Biomimicry was used to derive interdisciplinary similarities in the organic morphogenesis principle, and the result was categorized as a network system, folds and unfolds, pneumatic structures, auxetic growth, and membranes. The biomimetic fashion characteristics, including externalization of the body's interior, expansion of the body structure and silhouette, body protection, independence from the body, and post-human expression through virtualization, were analyzed. Morphogenetic processes performed through biomimetic vision are expected to aid in generating research on the possibility of mass production or popularization in the future through various experimental technical studies.

  • In this paper, we propose a biomimetic communication method using a dolphin whistle to covertly transmit the communication signal. A conventional CSS (Chirp Spread Spectrum) modulation technique divides dolphin whistle into several slots and modulates with up and down chirp signals. That causes the time-frequency characteristic difference between the original dolphin whistle and the camouflage performance is degraded. In this paper, we propose a delay based modulation scheme to eliminate distortions. The simulation results show that the bit error rate of the proposed method is better performance than that of the conventional CSS modulation method by about 3.5 dB to 8 dB. And the camouflage performance that evaluated through the cross correlation in the time-frequency domain is also better than that of the CSS modulation method.

  • This paper gives an overview on the some potential applications and key technologies of biomimetic underwater robot for naval operations. Unlike most manned underwater naval systems, biomimetic underwater robots can be especially useful in near-land or harbour areas due to their ability to operate in shallow water effectively. Biomimetic underwater robot provide advantages in reaching locations that would be difficult or too dangerous for a manned vehicle to reach, as well as providing a level of autonomy that can remove the requirement for dedicated human operator support. Using multiple or schools of underwater robots would provide increased flexibility for navigation, communication and surveillance ability. And it alleviate some of the restrictions associated with speed and endurance design constraints.
