“3DNagoonimation雷电将军”鸟腿结构对机3DNagoonimation雷电将军器人有何借鉴?最新研究称可助跳跃起飞

  北京3DNagoonimation雷电将军时间12月5日凌晨,国3DNagoonimation雷电将军际著3DNagoonimation雷电将军名学术期刊《自然》最新在线发表一篇工程学论文称,研究人员研发的一款机器人RAVEN拥有以鸟为灵感的腿部,能跳跃起飞,也能在地面上行走,越过障碍物。这一借鉴鸟腿结构的设计,可以让机器人飞行器在复杂地形中使用。

  该论文介绍,俗称鸟腿的鸟类后肢有各种功能,如走、跳、跨,以及跳跃起飞。这些能力有望应用于飞行机器人,但构建有多个运动模块的系统很难,因为这种系统的机械结构可能会过于复杂或沉重,导致无法顺利起飞。

  在本项研究中,论文第一作者兼通讯作者、瑞士洛桑联邦理工学院Won Dong Shin和同事及合作者一起克服了这些挑战,开发出命名为RAVEN的面向多环境的类禽机器人,该机器人的后肢能像鸟一样运动,其肢体的结构模拟了鸟的髋、踝和足,不过整个设计不像在鸟中看到的多段式腿部解剖结构那么复杂。

  论文作者表示,RAVEN能和鸟一样跳跃起飞,已知这能极大提升初始飞行起飞速度,而且比没有跳跃的起飞更节能。这种腿部设计还能切换多种运动步态,如行走、跳过缝隙和跳上障碍物。

  《自然》同期发表同行专家的“新闻与观点”文章认为,该研究虽然在其系统设计上仍需进一步优化,但在RAVEN腿部设计的启发下,今后有望设计出能使用多种运动模式的更多功能的机器人。

  论文作者还提供一组视频,科普解读演示他们最新发表的这项研究成果。
