A study on self reproduction of gel robot

我们对带正、负电荷的凝胶部件在水中搅拌条件下的自组装进行了实验研究，并在具有自复制能力的凝胶机器人方面取得了令人鼓舞的成果。首先，我们确认了通过在凝胶表面涂敷二氧化硅颗粒来提高粘附性能，并且可以通过pH值来控制粘附。接下来，为了获得部件连接的选择性，1）我们引入了对零件表面的选择性充电，实现了对粘合剂方向的控制。2）在胶面上引入几何形状，并利用不规则性进行接合，以保证胶贴在准确的位置。

We performed experimental study for self-assembly of gel parts charged positively and negatively in water under stirring and got promising results toward gel-robot that have an ability of self-reproduction.First, we confirmed that the adhesion performance is improved by applying the silica particles on the surface of the gel, and that it is possible to control the adhesion by pH. Next, in order to get the selectivity in parts connections, 1) we introduced a selective charging of parts surfaces to realize the adhesive direction control. And 2) we introduced a geometrical shape on the adhesive surface, and engaged using irregularities in order to adhere in an accurate position.
