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.

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.

In order to manufacture geometrically complex or hard material parts, a new kind of multi-axis electro-discharge machining (EDM) computer numerical control (CNC) system, which is based on RT-Linux platform, was presented. Dual-kernel structure of System is adopted: Linux and RT-Linux are used to realize Time-sharing tasks and Real-time tasks separately. The system is divided macroscopically into two parts: Real-time part and Time-sharing part, microcosmically into three modules: Real-time Control Module, Drive Module and CNC User Module. Through the communications among them, three modules construct the whole system. Rimed Turbine Blisk was experimentalized to validate the performance of the system. The process and the results implied that the system is Real-time, stable and reliable.

Acute disabilities always need different types of assistive devices in their daily life. Usually, each of these devices is designed for only one particular usage. Because of this, an acute disable may have to use a joystick to manipulate his wheelchair, used a mouse to control computer, or used a keyboard to control movement of mechanical arm. Thus no consideration of interrelations among these tools was discussed. In 1990, the technical working committee 173 (TC-173/sc-1/wg-7) of ISO (International Organization for Standardization) using serial interface protocol (ISO 7176-7) to integrate all types of assistive tools for the disabilities. At the same time, the European Common Commission funded the research for M3S interface (Multiple Masters Multiple Slave). It provides the disable a concrete integral control for his movement, working, environment control and communication. This is an integrated intelligent real time control capability protocol. It is a plug and play device interface. We design and develop a M3S protocol using TMS320F243 DSP chip. The system was tested for I/O control and it meets the equipments supported by the M3S working group. Thus, it would bring lots of comforts for the disable.
