今天在nao的平台上实现了一个功能,让一个机器人模仿你一个机器人的动作,目前是在python下检测出一个机器的各个关节的值然后 把这些关机的值传给另外的机器人,并且设置成它的关节值,但是这里有一个问题就是,主动的这个机器人在执行各个动作,好比执行站

    今天在nao的平台上实现了一个功能,让一个机器人模仿你一个机器人的动作,目前是在python下检测出一个机器的各个关节的值然后

把这些关机的值传给另外的机器人,并且设置成它的关节值,但是这里有一个问题就是,主动的这个机器人在执行各个动作,好比执行站起的动作时,它在内部是有很多的控制的,pid 插值,状态检测等等,所以主体机器人执行的很流畅,但是如果仅仅是把关节值传递给另外一个机器人,它的动作是完成不了的,简单的还勉强可以,但是复杂的就不行,因为它没有把所有的都克隆下来。

由于是第一次把程序下载机器人的系统里,所以还是把具体的步骤写一下:

     首先用WinSCP远程连接一个机器人,填写机器人地址192.168.1.146(具体视机器人定),用户名:nao

密码: nao. 点击登陆。打开PuTTY 在session目录下输入机器人ip地址:192.168.1.146 点击open 就打开一个控制终端了,因为在机器人的操作系统上(内核是linux 2.6.2*)安装有python解释器说以可以直接在它的操作系统里面建立python文件,编写程序(已近装有vim编辑器)并运行。

    

 

    最后的效果就是,你动一下一个机器人,另一个(这里是两个)也会做相同的动作。由于nao机器人平台开放了一些东西,我们现在是

利用它所开放的api来完成的。

    平台上能做的东西比较多,今天还看到了可以返回红球位置的一个函数,getPostion()但是不知道为什么

用它所属的代理来调用这个函数总是返回错误,要是能正确的返回那也就可以检测出红球的距离,并且机器人摄像头得距离也有一个函数可以用来获得这个值。这些将在后续的学习中继续。

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

MySQL vs. Other Programming Languages: A ComparisonMySQL vs. Other Programming Languages: A ComparisonApr 19, 2025 am 12:22 AM

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages ​​such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages ​​have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

Learning MySQL: A Step-by-Step Guide for New UsersLearning MySQL: A Step-by-Step Guide for New UsersApr 19, 2025 am 12:19 AM

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL: Essential Skills for Beginners to MasterMySQL: Essential Skills for Beginners to MasterApr 18, 2025 am 12:24 AM

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL: Structured Data and Relational DatabasesMySQL: Structured Data and Relational DatabasesApr 18, 2025 am 12:22 AM

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL: Key Features and Capabilities ExplainedMySQL: Key Features and Capabilities ExplainedApr 18, 2025 am 12:17 AM

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

The Purpose of SQL: Interacting with MySQL DatabasesThe Purpose of SQL: Interacting with MySQL DatabasesApr 18, 2025 am 12:12 AM

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

MySQL for Beginners: Getting Started with Database ManagementMySQL for Beginners: Getting Started with Database ManagementApr 18, 2025 am 12:10 AM

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA
