We propose an objective parallel computation/control method, developing the following to solve conventional problems and installing a controller on a robot with links decomposed to objects: 1) parallel calculation for twodimensional link dynamics, 2) downsizing of a high-speed controller using a digital signal processor (DSP), 3) a common robot control library, and 4) parallel calculation control of a multilink system. Evaluating parallel computation/control using the DSP, we verified fine compact controller efficiency in real-time control of multi-DOF systems and control performance comparing overall system control by linear quadratic optimal control.

It is a challenge to get real-time solutions for the inverse kinematics problem of 6R robot. In this study, a digital signal processor (DSP) was adopted as the central processor for the algorithm inverse kinematics. Based on it, the robot end-effector carried out the interpolation of point-to-point spatial straight line, and the inverse kinematics solving of 6R robot manipulators end-effector was achieved. The deflection variations of the 6 joints were acquired during the interpolation in a Cartesian coordinate. The results show that inverse Kinematics solution for each interpolation point only cost 0.06588 millisecond using DSP 6711. This hard structure can ensure the real-time performance of control for robot and content the real-time control performance expected of industrial manipulators.

As most controllers of the carton samplemaker using Industrial Personal Computer (IPC) architecture, its price is relatively expensive. Aiming at the actual situation of the high cost, low openness and big demand of the carton samplemaker, through the analysis of the control characteristics of it, the embedded Numerical Control (NC) platform based on the Advanced RISC Machines (ARM) and Digital Signal Processor (DSP) hardware architecture for carton samplemaker is designed. The overall framework of the platform and steps of the design are given in this paper. Windows CE embedded real-time operating system is adopted in the software design, and on this basis, the carton samplemaker applications is developed, which is mainly in charge of the motion control of the equipment and tasks management. The platform not only achieves the goals on real-time control, good speed and accuracy, but also has friendly operability. Finally, the introduction of the new dual-core chips gives a revelation on the future development in carton samplemaker.
