Http://www.ros.org/wiki/ Ros is a new super-portable robot programming system. Active Oxygen allows you to easily build distributed robot control systems on different languages and platforms. Ros is an open-source, meta-operating system for your

these registration information changes, allowing the node to dynamically create a connection to the new node.The connection between the node and the node is straightforward, and the controller provides only the query information, just like a DNS server. Node subscription a topic will require a connection to the node that publishes the topic, and the connection will be established on the basis of the consent Connection Agreement. another: Ros Controller control Services:Second, the file

Then, run the test program in the package: $ roslaunch Pocketsphinx Robocup.launch At this point, you will see a large segment of information in the terminal. Try to say some simple statements, of course, must be English, for example: Bring Me the g

] Name Address bindingthere must be a mechanism for each node's name (hostname) and its IP address to bind each other. Add machine name bindings in/etc/hosts, in the following format: IP hostname hostname sudo gedit/etc/hosts add Master's IP192.168.3.102 WSHIn the same master, add the IP of the computer to which you want to connect this master, such as Yxd192.168.3.102 Yxd env.sh environment variable settings use the

. From here, the CPU is a series of operations that can be used to process processes.The creation of processes, the destruction of the state of communication between transitions between synchronous asynchronous concurrency and the scheduling of processes. The details are as follows:3.2 Memory 内存的主要作用就是给cpu提供数据，既然是内存那就避免不免的流程： 分配 回收 我们所有的操作也都时围绕这俩点进行的，说道内存的分配那就肯定分为俩中情况： 连续 非连续 类似于数据结构 的线性和非线性。 连续分配内存就是很简单了，就是分配连续的内存，但是分配多少呢，这就是一个问题了，所以就分为固定内存的分配 和动态内存的分配（根据程序，数据 大小），并且采用相关的分配算法。缺点：内存碎片化

Is there any book on the classic operating system and composition principles ~ -- Linux general technology-Linux technology and application information. For details, refer to the following section. I am currently studying LINUX and want to develop it in the future! I am a professional in information management and have never studied data structures,

and no process to use the corresponding structure, then the corresponding memory area is returned to the memory management module. Implementation of the 2.5 scheduler A unique description of each process is saved in memory and is connected to other processes through several structures. This is the case with the scheduler, whose task is to share CPU time between programs, creating the illusion of parallel execution. As discussed above, the task is divided into two different parts: one involving

8259 programmable interrupt controller (PIC) is one of the most important chips making up the X86 architecture. without it, the X86 architecture wocould not be an interrupt driven architecture. the function of the 8259a is to manage hardware interrupts and send them to the appropriate system interrupt. this allows the system to respond to devices needs without loss of time (from polling the device, for ins

Compared with the Open-loop control system, the walking path can be shortened effectively, the walking speed is increased By 5.66% and The walking time was shortened by 7.25%, whichverifies the feasibility and practicability of the Closed-loop control system.Key words:hexapod Robot Autonomous Navigation fuzzy neural network closed-loop control environment

Recently learned the Ros robot system, we all know that Ros is based on the Linux platform, of course, if the application of Ros to Windows, Android, IOS, WP system can also be downloaded as long as the corresponding ROS development package is OK, but the configuration of these environments is a very painful thing, Because there are many versions of Ros, not ever
