A study on self reproduction of gel robot

我们对水中带正负电荷的凝胶部件在搅拌作用下的自组装进行了实验研究，得到了具有自复制能力的凝胶机器人的实验结果。首先，我们证实了在凝胶表面应用二氧化硅颗粒可以改善凝胶的附着性能，并且可以通过pH来控制附着。其次，为了获得零件连接的选择性，1)引入了零件表面的选择性充电来实现粘接方向的控制。2)在粘接剂表面引入几何形状，并使用不规则啮合，以实现准确的粘接位置。

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.
