我国成功研制新型人工皮肤,为机器人提供触觉

  近日,合肥智能机械研究所和合肥工业大学联合研制成功一款新型的“人工皮肤”,这是我国首次研制出的用于监测“三维力”的机器人触觉传感器。这种皮肤有什么样的优势?可以在哪些方面得到应用呢?

  所谓可以检测三维力的“人工皮肤”,即,可以实时的检测具体的受力点和三个方向的力,它不仅包括垂直方向的压力,而且还包括侧向的摩擦力。它综合应用了材料科学、纳米技术、传感技术和人工智能理论。


  “‘人工皮肤’是一种用于智能机器人的‘皮肤’,它能为机器人提供触觉信息,是一种类皮肤的阵列触觉传感器,其可以感觉到外界施加在‘皮肤’上的力信息。”中国科学院合肥智能机械研究所研究员葛运建介绍说,“我们研究出来的‘人工皮肤’之所以不同凡响,是因为其可以连续检测作用在它面上的来自多个方向的力信息。”

  “与前代的机器人‘人造皮肤’不同,以前的机器人皮肤或只能检测一维力,即来自一个方向的力。要达到能检测三维力,‘人造皮肤’则是由一块一块单独的传感器单元附着在一个柔性材料上组成的,就如同古代士兵穿的盔甲,每一个传感器单元都不是柔性的,也不能实现完全的连续测量。这次推出的这种新型‘人造皮肤’,没有单独的传感器单元,传感器阵列是一个整体,就像是乒乓球拍上的海绵和汽车的轮胎,整体上非常柔软,可以扭转和拉伸打破了‘铠甲’式阵列传感器的缺陷,打个比方就像是乒乓球拍上的海绵和车带的轮胎,是一种完全新型的三维柔性阵列触觉传感器。”葛运建说。

  葛运建进一步解释说:“新型‘人工皮肤’的基体材料是一种新研制的可以流动成型的导电胶,制作工艺就好像浇注建房子的预制板,先搭建一个钢筋的骨架,然后再灌入水泥和沙子使其成为一个整体,‘人工皮肤’就是在上下两层布置了网格一样的导电节点,中间灌入新型导电胶。”
