robots

robots是網站跟爬蟲間的協議,用簡單直接的txt格式文本方式告訴對應的爬蟲被允許的權限,也就是說robots.txt是搜索引擎中訪問網站的時候要查看的第一個文件。當一個搜索蜘蛛訪問一個站點時,它會首先檢查該站點根目錄下是否存在robots.txt,如果存在,搜索機器人就會按照該文件中的內容來確定訪問的范圍;如果該文件不存在,所有的搜索蜘蛛將能夠訪問網站上所有沒有被口令保護的頁面。

  • 采用TüV認證的FPGA開發功能安全系統

    This white paper discusses how market trends, the need for increased productivity, and new legislation have accelerated the use of safety systems in industrial machinery. This TÜV-qualified FPGA design methodology is changing the paradigms of safety designs and will greatly reduce development effort, system complexity, and time to market. This allows FPGA users to design their own customized safety controllers and provides a significant competitive advantage over traditional microcontroller or ASIC-based designs. Introduction The basic motivation of deploying functional safety systems is to ensure safe operation as well as safe behavior in cases of failure. Examples of functional safety systems include train brakes, proximity sensors for hazardous areas around machines such as fast-moving robots, and distributed control systems in process automation equipment such as those used in petrochemical plants. The International Electrotechnical Commission’s standard, IEC 61508: “Functional safety of electrical/electronic/programmable electronic safety-related systems,” is understood as the standard for designing safety systems for electrical, electronic, and programmable electronic (E/E/PE) equipment. This standard was developed in the mid-1980s and has been revised several times to cover the technical advances in various industries. In addition, derivative standards have been developed for specific markets and applications that prescribe the particular requirements on functional safety systems in these industry applications. Example applications include process automation (IEC 61511), machine automation (IEC 62061), transportation (railway EN 50128), medical (IEC 62304), automotive (ISO 26262), power generation, distribution, and transportation. 圖Figure 1.

    Robotics TOOLBOX The Toolbox provides many functions that are useful in robotics including such things as kinematics, dynamics, and trajectory generation. The Toolbox is useful for simulation as well as analyzing results from experiments with real robots. Have fun with the toolbox. It is self-explanatory and very (robotics) user friendly...see the robot.pdf

  • PTypes (C++ Portable Types Library) is a simple alternative to the STL that includes multithreading

    PTypes (C++ Portable Types Library) is a simple alternative to the STL that includes multithreading and networking. It defines dynamic strings, variants, character sets, lists and other basic data types along with threads, synchronization objects, IP sockets and named pipes. PTypes also offers message queues as an alternative method of thread synchronization. Its main `target audience is developers of complex network daemons, robots or non-visual client/server applications of any kind
