In ROS 1 all information about the ROS graph must be polled from the master. In ROS 2 changes will be published instead, e.g. notifications if a parameter has been changed. 具有生命周期的组件 Components with life cycle 在ROS 1中,每个节点通常都有自己的主要功能。在ROS 2中,建议从具有生命周...
It’s also possible to use full parameter names: 也可以使用完整的参数名称: rosparam Available in ROS1. ROS1中提供。 Loads parameters from a yaml file. 从yaml文件加载参数。 It has been replaced with a from atribute in param tags. 它已从from属性替换param标签。 Example 示例 remap 重映射 Av...
例如:copytree(source, destination, ignore=ignore_patterns('*.pyc', 'tmp*')) def ignore_patterns(*patterns): """Function that can be used as copytree() ignore parameter. Patterns is a sequence of glob-style patterns that are used to exclude files""" def _ignore_patterns(path, names): i...

It's able to get a std::shared_ptr to a NodeWaitablesInterface so long as the class has a method called get_node_waitables_interface() which returns one. Typedef Documentation ◆ ParameterMap using rclcpp::ParameterMap = typedef std::unordered_map<std::string, std::vector<Parameter> > A...
Parameters in ROS 2 are based on services, and as such have a similar profile. The difference is thatparameters use a much larger queue depth so that requests do not get lost when, for example, theparameter client is unable to reach the parameter service server. ...

Ros2 - Moveit2 - TimeParameter(时间参数化) 时间参数化 MoveIt 目前主要是一个运动规划框架 - 它规划关节或末端执行器的位置,但不规划速度或加速度。但是,MoveIt 确实利用后处理来对速度和加速度值的运动轨迹进行时间参数化。下面我们将解释 MoveIt 这一部分所涉及的设置和组件。
