首先介绍了球形机器人的发展状况，在了解前人研究领域的基础上，应用微分几何控制理论，对此角动量守恒的球形机器人的非完整性和非线性可控性进行了研究。

Furthermore, we define a convolution multiplication between characteristic functions of constructible subsets by using push-forward functor from the category of algebraic varieties over C to the category of spaces of constructible functions.
