Raptorial forelegs are prey capturing and grasping devices, best known among insects in praying mantises (Insecta: Mantodea). Mantodeans show strong morphological and behavioral adaptations towards the lifestyle of an ambush predator, with specific environmental influences and preferences of particular prey, resulting in distinct ecomorphological adaptations. Using a combination of micro-computed tomography, confocal laser scanning microscopy, scanning electron microscopy and morphological angle measurments for morphological assessment, as well as high-speed videography with motion tracking analysis for kinematic analysis and behavioural observations, this project aims to elucidate principles of prey capturing in Mantodea. Furthermore, mechanical experiments employing 3D-printing and force measurements as well as bio-inspired robotics will used to learn about the biomechanics behind the predatory strike and to inspire technology. Expected results will improve our knowledge about the biomechanical aspects of the prey capture process, as well as novel insights into the material composition of involved cuticular structures, possibly serving as a new source of inspiration for biomimetic approaches; for example, in robotic grasping systems.

猛禽前肢是捕获和抓取猎物的装置，在螳螂（昆虫纲：螳螂目）昆虫中最为知名。Mantodeans表现出强烈的形态和行为的生活方式的伏击捕食者的适应，特定的环境影响和偏好的特定猎物，导致不同的生态形态适应。本项目结合微计算机断层扫描、共聚焦激光扫描显微镜、扫描电子显微镜和形态角度测量进行形态学评估，并结合高速摄像与运动跟踪分析进行运动学分析和行为观察，旨在阐明Mantodea捕食的原理。此外，采用3D打印和力测量的机械实验以及生物启发的机器人技术将用于了解掠夺性罢工背后的生物力学并激发技术。预期的结果将提高我们的猎物捕获过程的生物力学方面的知识，以及新的见解涉及表皮结构的材料组成，可能作为一个新的灵感来源仿生方法，例如，在机器人抓系统。
