引用\[1\]:出现如下报错信息: \[ INFO\] \[1564730909.628248268\]: Constructing new MoveGroup connection for group 'arm_group' in namespace '' \[ INFO\] \[1564730910.984667942\]: MoveItSimpleControllerManager: Waiting for redwall_arm/follow_joint_trajectory to come up \[ERROR\] \[1564730915.984849668\]: MoveItSimpleControllerManager: Action client not connected: redwall_arm/follow_joint_trajectory \[ INFO\] \[1564730916.087709422\]: Returned 0 controllers in list \[ INFO\] \[1564730916.107154984\]: Trajectory execution is managing controllers 。
引用\[2\]:发现竟然没有找到follow_joint_trajectory消息,难道move_group没有发布吗?纠结了一天,终于找到原因了,之前虚拟机械臂有gazebo的ros_control插件自动帮我们获取了follow_joint_trajectory的动作action信息,现在到真实机器人了,需要我们自己写程序了。问题找到了,最重要的是要理解一点,move_group此时是follow_joint_trajectory的client端,动作消息是client端的move_group发布的,听起来有点绕,但是千万不要把报错信息的action client not connect搞混淆了,我们现在client是存在且被感知的(就是move_group),而之所以报错是因为我缺少了action server端,我们需要添加一个server订阅这个action。

问题:constructing new movegroup connection for group 'manipulator' in namespace
回答: 根据提供的引用内容,报错信息中显示正在构建一个新的MoveGroup连接,连接的组是'manipulator',命名空间为空。\[1\]这个报错信息表明正在尝试建立一个名为'manipulator'的组的MoveGroup连接。然而,报错信息中还显示了一个错误,即Action client 'redwall_arm/follow_joint_trajectory'未连接。\[2\]这可能是因为缺少一个action server端,需要添加一个server来订阅这个action。根据提供的信息,还无法确定是否已经在命名空间中找到了'manipulator'组的相关信息。
