The robot's structure was designed with Pro/Engineer and AutoCAD software. Secondly, the kinematics analysis conducted, coordinate transformation matrix using D-H method was set up, and the kinematics equation direct solution and inverse solution was deduced.

There is no one kind of thing that we 'perceive' but many different kinds, the number being reducible if at all by scientific investigation and not by philosophy: pens are in many ways though not in all ways unlike rainbows, which are in many ways though not in all ways but not in all ways unlike pictures on the cinema-screen-- and so on, without assignable limit. So we are not to look for an answer to the question, what kind of thing we perceive. What we have above all to do is, negatively, to rid ourselves of such illusions as 'the argument from illusion'--an 'argument' which those (e.g Berkeley, Hume, Russell, Ayer) who have been most adept at working it, most fully masters of a certain special, happy style of blinkering philosophical English, we have all themselves felt to be somehow spurious.

我们&感知&到的不是唯一的一类东西，而是林林总总、纷繁各异的事物；它们的数目即便可以归约化简，那也应是科学研究而非哲学思考的任务：在很多方面，但并非在所有方面，钢笔异於虹霓，虹霓又在很多方面虽非在所有方面异於视觉后象，视觉后象又在很多方面虽非在所有方面异於银幕上的图像――如此等等，没有可以简单划分的界线。
