这段代码是一个移动机器人到目标点的函数。具体来说，它等待连接到move_base服务器，然后设置目标点的位置和姿态，发送目标点并等待机器人到达目标点。如果机器人成功到达目标点，返回true；否则，返回false。

其中，move_base是一个ROS的action，用于控制机器人移动到目标点。move_base.waitForServer()会等待连接到move_base服务器，如果5秒内没有连接成功，则会输出“Waiting for move_base action server...”，表示等待中。ROS_INFO()用于输出一些ROS相关的信息。target_odom_point是一个表示目标点位置和姿态的变量。tf库是ROS中的一个库，用于坐标系的转换和变换。其中，getRPY()函数将四元数转换成欧拉角（roll、pitch和yaw）。如果yaw大于3.14，就需要旋转到相反的方向，然后计算新的目标点位置和姿态。ROS中有很多库和工具可以用于机器人的控制和导航，需要根据具体的需求选择合适的库和工具。

这段代码是一个移动机器人到目标点的函数。首先会等待 move_base action server 的连接，如果在 5 秒内没有连接成功，则会输出 "Waiting for move_base action server..."。如果连接成功，则会输出 "Connected to move base server"。

接下来，设置目标点的坐标和姿态，这里的目标点是以地图为参考系的。然后通过计算机器人需要旋转的角度，将目标点向机器人前进方向偏移一定距离，即目标点距离机器人保持一定距离。最后通过 move_base.sendGoal(goal) 发送目标点，等待机器人到达目标点，如果成功到达则返回 true，否则返回 false。
