Examples Of Kinematics• 73 Downloads • Abstract Multi-loop spatial mechanisms, or parallel mechanisms, are being used to an increasing degree in robotic applications, because they offer some advantages over the open-chain mechanisms. In fact they exhibit high stiffness and low inertia, a fair compliance to the design requirements, and the ability to hold the power actuators in the base. On the other hand, they are often so complex that they can be analyzed only by digital computers, and in general they are designed on the basis of practical solutions rather than theoretical investigations of their structure and kinematics. This paper on the kinematic analysis of multi-loop spatial mechanisms deals in particular with manipulators with five loops and lower pairs. Two approaches are outlined, according to the different backgrounds of the authors: the decomposition method [9], and a differential approach to the non-linear equation set, 19.(6) which encompasses the direct and inverse kinematic problems, as well as the synthesis of the robot. The results are then specialized for mechanisms with the end-effector supported by three spatial parallelograms, like the DELTA-4 robot. I made a text file that said: 'This is a pdf test' I then excuted the script from a DOS window: C: Python>pyText2Pdf.py tmp.txt [] ['tmp.txt'] Using font Courier size = 10 Input file = tmp.txt Writing pdf file tmp.txt.pdf. I think you mean: _For_ more python scripts. Can i append the text file to existing PDF file. I'm also using Python 2.3b1 Also, in your help text, you say: _Fore_ more python scripts. Wrote file tmp.txt.pdf I'm using Adobe Acrobat v4.05a 1124 on a Windows 2K machine. Programmieren lernen.
