查询词典 rectangular cartesian coordinate system

By using the Lagrangian approach, the explicit dynamic model in the Cartesian space and joint space is created. The model has taken full account of the influences of the length variation of the driving links and the orientation of the translational mechanism.

其次，本文应用拉格朗日方法首次系统地建立了该并联机器人在操作空间和关节空间的显式动力学模型，该模型充分考虑驱动杆长度变化和平动机构位姿变化对操作力的影响。

Previously, researchers raised the accuracy that a robot′s hand tracks a specified path in Cartesian space mainly through increasing the number of knots on the path and the number of the path′s segments.

在以往的研究中，往往是通过在设定的路径上增加节点数和路径分段数来提高机器人手部跟踪设定路径的精度，但这种方法会导致在线计算量大幅度增加。

The algorithm GS to solve the problem of inverse dynamics based on the optimal theory is proposed, by using the numerical methods of Gill and shooting target, the optimal joint driven torques are obtained With the smooth joint trajectory motion, a fast and stable inverse dynamics method is proposed, it provides a new effective way to control the flexible manipulator The trajectory planning in the joint space and Cartesian coordinates is especially discussed In terms of kinematics of space flexible link manipulators, a sequential integration method for inverse dynamic analysis of flexible manipulators is developed The concrete results of simulations tested and verified the validity of proposed methods, and some valuable conclusions are achieved.

提出了求解基于最优理论的柔性臂逆动力学问题的GS法(Gill—Shooting method)，得到了柔性臂关节的最优驱动力矩；提出了基于光滑关节运动轨迹的柔性臂逆动力学的快速稳定方法，为柔性臂控制提供了一条新的途径；探讨了关节空间和直角坐标空间柔性臂的轨迹规划问题；研究并完善了结合柔性臂运动学的顺序积分的逆动力学方法。通过具体实例的仿真研究，验证了所提出的柔性臂逆动力学方法的有效性，得出了一些很有价值的结论。

In this chapter you will use the same concepts of graphing but now on a Cartesian grid.

在这一章中你将使用相同的概念，图形，但现在的直角坐标网格。

And a basic understanding of Cartesian geometry, too.

和一些理解解析几何的知识。

When we talk about being rational, we don't need to box ourselves into Cartesian reasoning.

当我说要理性时，我们并不一定要把我们自己局限在笛卡尔式的理性。

It is Cartesian because it allows x-y-z positioning.

这是笛卡尔的因为它可以让x-y-z坐标系定位。

So I shall be concerned with why we should be dualists, and why dualists of a Cartesian stripe.

所以，我将关心为什么我们应该是二元论者，为什么倾向于笛卡尔式的二元论者。

Don not attempt to do something which you can not to do.
