Bionic grippers and soft robots

Future concepts from the Bionic Learning Network

All natural movements tell a story of adaptation and efficiency, whether these are the precise finger movements of a pianist, the skilful catching techniques of a chameleon or the powerful plucking ability of an elephant's trunk. Over the years, our bionics team has developed a large number of bionic grippers and pneumatic lightweight robot arms, all of which can effortlessly execute the flowing motion sequences of their natural counterparts. Click through our bionic concepts that provideinspiration for our core business of automation technology.


From the bionic concept to the series product

Gripping has always played an important role in the Bionic Learning Network. Nature is often a source of amazing ideas and new solutions for industrial applications. Numerous bionic gripping applications have already been developed as part of the network’s interdisciplinary research work, and this has led to two concepts being developed into series products.


形状自适应抓手 DHEF:拥有变色龙的舌头一样的超强适应性

形状自适应抓手 DHEFFlexShapeGripper 的高级形态。 它的作用原理源自变色龙的舌头。 为了捕捉猎物,这种动物的舌头会像橡皮筋一样弹出。 在舌尖即将触及昆虫时,中间部位往后退,而边缘则继续向前移动。 因此,舌头能够适应猎物的形状和大小,并紧紧包裹住猎物。

这款抓手的主要组件是硅胶帽,其中稍微过压。硅胶帽仿照变色龙的舌头制成,可以灵活地紧紧固定在所抓握的材料上, 从而包围和固定住抓握的物体。 利用比例阀提供的适当驱动力,甚至可以一次抓取多个物体,例如碗中的螺钉。


灵感来自鱼鳍的自适应抓手指 DHAS

自适应抓手指 DHAS 的灵感来源于鱼类尾鳍能够做出的精巧行为。 如果从侧面按压鳍片,鳍片不会弯曲移开,而是围绕压力点形成拱形。 开发人员借助两片通过中间小连杆相互连接的柔性聚氨酯长条,将这种人们称之为 Fin Ray Effect®(鳍条效应)融入到他们的工程设计中。

无论是平行,还是居中排列: 在抓取时,稳定而灵活的抓手指可轻松适应工件的轮廓。 因而,可以轻柔而安全地抓握表面不规则的外界敏感型物体。 DHAS 已在食品行业得到应用,人们可以将其用于对水果和蔬菜进行分类。
