麻省理工学院create fish-catching soft robot using 3D printing

麻省理工学院的研究人员使用3D打印来创建一种可以捕获和释放活鱼的新水凝胶设备。透明的凝胶机器人可以执行许多涉及强大动作的任务,例如抓取和释放。

Massachusetts Institute of Technology are known for their pioneering 3D printing research. Recently MIT researchers published a study focusing on在后期制作中调整3D打印对象phase and also评估如何使用石墨烯进行3D打印

Elsewhere in the field of soft robotics,Harvard recently used 3D printing to create their Octobot device被誉为世界上第一个完全软机器人。

它是如何工作的?

该设备可以比作类似于施工机或街机机中使用的爪起重机。为了运作,将水泵入机器人的3D印刷臂中。这些空心结构膨胀,使机器人“to curl up or stretch out.”该技术意味着机器人可以每秒以几个纽顿的力量迅速扩展和收缩。

该设备由透明的水凝胶材料制成,因此机器人几乎完全由水形成。该物质本质上是柔软的,因此能够非常细致地抓住像鱼类这样的物体。将其添加到其透明度中,该设备非常擅长偷偷捕获鱼(如下所示)。

The research group

The clever aquatic robot was developed at MIT by graduate student Hyunwoo Yuk under the supervision of associate professor of mechanical engineering and civil and environmental engineering Xuanhe Zhao. The research group have developed several forms of these hydrogel robots, “包括一个来回拍打的鳍状结构,一个使踢动作的铰接附属物以及一个柔软的手形机器人,可以挤压和放松。”康奈尔大学的研究人员最近还开发了自己的手形软机器人the GentleBot, which can feel external objects

Zhao副教授详细介绍了其捕鱼能力,

[机器人]几乎是透明的,很难看到。当您释放鱼时,这​​很高兴,因为[机器人]柔软并且不会损坏鱼。想象一下硬机器人手可能会挤压鱼。

But why?

There is, of course, more potential for this robot than catching and releasing fish. The team have explained that it could have medical application such as use in surgery. While the soft robot would not need to be transparent, the device would be beneficial for handling delicate body tissue. Particularly since the soft robot’s hydrogel material is biocompatible.

赵解释了这项研究的潜力,

水凝胶柔软,湿,生物相容性,可以与人体器官形成更友好的界面。我们正在与医疗团体积极合作,将该系统转化为软凝胶“ Hands”等软操作机,这些操作可能会在手术操作中对组织和器官进行更轻柔的操纵。

The MIT research team have published their findings this week in the自然通讯杂志
