Edit descriptors

Formatted data transferred to or from an external medium require the exact formatting of the data to be specified. All aspects of how this may be achieved are fully described in this chapter. The various types of data edit and control descriptor are listed, together with methods to control file connection modes and to manage the formatting of entities of a derived-data type.

Design and Control System of Parallel Kinematic Manipulator

This paper presents parallel kinematic manipulator design. A manipulator with three axis and parallelogram mechanism was made using aluminium profile rods. This mechanism was controlled by PC with the use of stepper motors. Kinematics analysis was conducted and its findings were used to make a special software to generate G-code control file. X and y mouse cursor indications with given z value were used as data showing the position of the effector to establish the movement of the arms of the presented manipulator. Step2CNC software was used to control the manipulator. Tests have confirmed the correctness of the study.
