Multi-material Bio-inspired Soft Octopus Robot for Underwater Synchronous Swimming

Inspired by the simple yet amazing morphology of the Octopus, we propose the design, fabrication, and characterization of multi-material bio-inspired soft Octopus robot (Octobot). 3D printed molds for tentacles and head were used. The tentacles of the Octobot were casted using Ecoflex-0030 while head was fabricated using relatively flexible material, i.e., OOMOO-25. The head is attached to the functionally responsive tentacles (each tentacle is of 79.12 mm length and 7 void space diameter), whereas Shape Memory Alloy (SMA) muscle wires of 0.5 mm thickness are used in Octobot tentacles for dual thrust generation and actuation of Octobot. The tentacles were separated in two groups and were synchronously actuated. Each tentacle of the developed Octobot contains a pair of SMA muscles (SMA-α and SMA-β). SMA-α muscles being the main actuator, was powered by 9 V, 350 mA power supply, whereas SMA-β was used to provide back thrust and thus helps to increase the actuation frequency. Simulation work of the proposed model was performed in the SolidWorks environment to verify the vertical velocity using the octopus tentacle actuation. The design morphology of Octobot was optimized using simulation and TRACKER software by analyzing the experimental data of angle, displacement, and velocity of real octopus. The as-developed Octobot can swim at variable frequencies (0.5–2 Hz) with the average speed of 25 mm/s (0.5 BLS). Therefore, the proposed soft Octopus robot showed an excellent capability of mimicking the gait pattern of its natural counterpart.

青藏高原及其周边地区具有漫长且复杂的构造演化历史.印度北部、拉萨、羌塘、柴达木、中祁连等大小不同的克拉通和地块,以及位于它们之间的造山带构成了青藏高原的主体.寒武纪时期,这些克拉通和地块大多位于冈瓦纳大陆的西北缘,并以发育与原特提斯洋有关的复杂岩浆-构造运动而与周边的阿拉伯、中伊朗、阿富汗、塔里木、阿拉善、华北、华南和滇缅马等构造单元相关联.从地层记录上看,这一时期区域内的大部分稳定陆块上发育了由陆源碎屑岩和碳酸盐岩组成的浅水陆棚沉积,其中包含面貌相近的典型浅水相三叶虫组合.而在原特提斯洋中的祁连构造带,寒武系则是一套在大洋扩张环境下形成的、以中基性火山岩和硅质岩为主的复杂地层序列,其中包含的碳酸盐岩含有斜坡相三叶虫组合.本文在广泛文献调研的基础上,结合第二次青藏高原综合科学考察中的野外观察及新获得的化石证据,对青藏高原及其周边地区不同构造单元上寒武纪地层发育的总体特征进行了概述.在此基础上,利用可获得的生物地层学和同位素年代学等资料,总结了不同构造单元上寒武纪地层的划分和年代地层对比,编制了岩石和生物地层的综合对比表.此外,从生物古地理的角度,简要讨论了寒武纪研究区内主要构造单元的古地理相关性,以及与原特提斯构造带演变有关的问题.
