ROS is an open-source, meta-operating system for your robot. It provides the services you would expect from an operating system, including hardware abstraction, low-level device control, implementation of commonly-used functionality, message-passing between processes, and package management.

问题描述：在mac下装LEGO的软件，装好后发现没有可用程序，然后网上找啊找，找到以下方法：
To install LEGO MINDSTORMS NXT 2.0 on Mac OS 10.6 (Snow Leopard)
1. Copy all files from the MINDSTORMS CD to a folder on your desktop.
2. Open that folder and look under "Parts".
3. Locate MindstormsUnivEdu.pkg or MindstormsUnivRet.pkg.
4. Right-click (control-click) and choose "Show Package Contents".
5. Navigate into the Contents/Resources directory and delete the "preflight" file.
6. Close this package and run the meta-package from the desktop to install MINDSTORMS NXT
试了，无效，然后再找啊找，找到LEGO针对Snow Leopard补丁：http://mindstorms.lego.com/en-us/support/files/Patches.aspx
问题解决：下载其补丁，会再桌面生成一个安装光盘的copy，然后会自动进行安装。一切OK了。
最近开始研究机器人，以下是一些流行的机器人套件：
Arduino，主要是做一些互动装置，也可以用来做简单的机器人。
Asuro，主要做的是带轮子的机器人。
Bioloid，百变网聚机器人，分成一个个小关节模块，自由组装。
Lego，乐高玩具机器人，娱乐性大。
