What's more, therelationship is built up between the joint space of robot and theworld space.

基于几何投影原理推导出相应的逆运动学模型，求出了各个关节的角度值，建立了机器人关节空间与世界空间的映射关系。

The control of a robot with unactuated joints is much more difficult than a conventional robot. Because the unactuated joints can't be controlled directly, it is an incomplete controllable system. Usual smooth feedback control is not usable for such system.

引言在一般的机器人控制中，机器人各关节是由各自的电机分别控制驱动的，这样在运动控制上非常简单，一般的只需要做运动学反向解，通过位置反馈控制来实现预定的运动轨道。

This paper also discusses the dynamic steering feature and determines the length of the wheelbase for better miming.

同时分析了半挂汽车转弯时的运动学特征并确定了半挂车轴距的长度，以保证整个半挂汽车的稳定行驶。

Therefore, in this thesis, a new set of models about breaking probability and whitecap coverage is set up using this breaking criterion. Under the assumption of linear ocean waves, and in the light of the theoretical framework about the probabilistic distribution of wave characteristics (Sun Fu 1988), several probabilistic distributions of wave characteristics that is necessary for the estimation of breaking probability and whitecap coverage are derived.

在线性海浪假设下，基于孙孚（1988）关于三维海浪要素统计分布的理论框架，具体给出二维海浪波峰处质点水平速度和表观相速的联合分布等分布函数，在此基础上，根据运动学判据，分别建立起风浪破碎率和白浪覆盖率的理论模式。

Because it is not practical to use numerical ephemerides with a large volume of data to describe the kinematics of component stars in a star catalogue, a kinematics model, as simple and practical as possible, is needed for the hierarchical triple star systems.

因为在实用星表参考架中不宜采用数据量较大的数值历表来描述子星的运动，所以有必要针对等级三星系统建立尽可能简单实用的运动学模型。

Kinematics and geodynamic modeling of continental deformation, along with thermal-rheological structure of the continental lithosphere are all emphasized here for study in future.

所以，大陆动力学应注重开展大陆变形的运动学、大陆岩石圈的热－流变学结构和大陆变形的地球动力学数值模拟研究。
