In view of the key problem of subminiature underwater robots, structural improving,control algorithm and underwater experiment is studied. They can be described as follow: Firstly, the subminiature underwater robot should be compact in size and low cost, for which, it is difficult for us to control its balance. So that, a new kind of piston--style ups and downs system was invented, which can keep the underwater robot horizontally suspended in the water without driving force.

中文摘要本文针对超小型水下机器人在运动中存在的问题，设计了一种新的超小型水下机器人的沉浮结构形式，着重研究了其运动学动力学性能、探讨了相应控制算法、进行了水下试验，具体研究内容如下：首先，超小型水下机器人由于体积小重量轻，在水中沉浮时悬停平衡控制困难，为此进行了一种新的活塞式沉浮系统设计，该系统使水下机器人能够在无动力驱动的情况下，使其呈水平状态稳定悬浮在水中。
