In this paper we describe a control methodology for catching a fast moving object with a robot manipulator, where visual information is employed to track the trajectory of the target. Sensing, planning and control are performed in real-time t

就C++而言，不少程序员只是简单地用printf来输出日志，或者临时写个日志类，log4cpp等比较“重型”的日志库的使用率反而并不怎么高（至少从我经历的项目而言）。也许是不想为不需要的功能付出额外的学习成本，但无论如何，对于通用类别的工具采取临时手写的方式来应付，从长远考虑，在功能性和健壮性方面是得不偿失的。写这个日志类(yaolog)的最初的想法只是为了实现“输出到文件的带有时间信息的printf”，后来历经不同项目需求的“拷问”，借鉴和引用了很多开源代码（在此对那些作者表示感谢），就成了现
