鱼总,四驱板的原理图没有防反接电路和和连接上位机的串口电路吗?
ros2 humble和gazebo 11为什么使用gazebo加载机器人模型和世界没有/gazebo/ "model_states" 话题发布
输入ros2 topic echo /gazebo/model_states显示错误
WARNING: topic [/gazebo/model_states] does not appear to be published yet
Could not determine the type for the passed topic
怎么解决,谢谢
如题,还想问问摄像头能够在通过wifi,把视频保存在电脑上吗?我想采集小车前后左右四个角度的视频
1:大家有没有复杂一些的工业级机器人源码可以分享?比如玻璃清洁机器人,泳池清洁机器人,或者较复杂的机械臂、视觉识别、空间定位之类的
2:感觉仅仅依赖社区的框架,很难做出复杂的或解决特定问题的机器人,但是自己做缺乏方向,有没有各个方向深入一些的路线或学习资料
环境是wsl fishbot gazebo模拟

学习ROS2中途安装了一个miniconda,然后就出现了各种各样环境兼容的问题。先是vscode打不开,后来发现用colcon build的时候生成不了可执行文件和接口库文件,安装miniconda之前的文件可以生成可执行文件,但是之后的就不行。
问题描述:colcon build没办法正确生成可执行文件,没有报错,但就是会忽略掉在cmakelist里配置好的文件,需要手动生成。应该是因为中途安装了一个miniconda,配置了环境之后就坏掉了。我不会调,所以直接把miniconda卸载了。但还是没法正确编译。在同一个功能包里,有的可以正确编译生成可执行文件,有的不行。colcon build也可以正常运行,不报错。
具体细节和上下文:可以看到没有报错,但是在同一个功能包chapt4_interfaces下的facedector在install/srv下生成了库文件,但是partol没有。cpp和python文件也是类似,可执行文件和库文件都没办法正确生成,就不截图了。
0da19b52-baaf-45cd-a344-4a2d3e739df8-图片.png
以下是chapt4_interfaces对应的cmakelist文件:
以下是package.xml的内容
<?xml version="1.0"?> <?xml-model href="http://download.ros.org/schema/package_format3.xsd" schematypens="http://www.w3.org/2001/XMLSchema"?> <package format="3"> <name>chapt4_interfaces</name> <version>0.0.0</version> <description>TODO: Package description</description> <maintainer email="aroughwelcome@163.com">phoebe</maintainer> <license>Apache-2.0</license> <buildtool_depend>ament_cmake</buildtool_depend> <member_of_group>rosidl_interface_packages</member_of_group> <depend>sensor_msgs</depend> <depend>rosidl_default_generators</depend> <test_depend>ament_lint_auto</test_depend> <test_depend>ament_lint_common</test_depend> <export> <build_type>ament_cmake</build_type> </export> </package> 尝试过的解决方法:现在已经把miniconda卸载了,vscode也重装了,ROS和环境也重新配置了一遍。但还是没法正确编译。
手动生成的话是可以正常生成可执行文件的。
【我不太了解,有什么需要补充或者可以尝试的,请大家告诉我。我会积极修改的,谢谢^ ^】

用一键安装ros2后,发现没有rqt_robot_steering包,sudo apt install ros-humble-rqt-robot-steering安装启动后,再启动ros2 run turtlesim turtlesim_node,在/cmd_vel前添加turtle1,发现控制不了小乌龟运动
具体需要改动哪部分啊
我启动官方的turtlebot3_simulations/turtlebot3_gazebo/launch/multi_robot.launch.py,官方的为3个turtlebot3同时启动,因为需要完成多机器人导航,我为了先测试修改为启动1个小车,这个小车都添加了命名空间TB3_1。
然后我将官方的turtlebot3_navigation2/launch/navigation2.launch.py中的这一部分也添加了命名空间

tf树里也没有map

我想问问是不是我这样的修改想法太简单了,已经困扰了我好多天了,我也试过修改burger.yaml里面的参数文件,同样也是没有效果,所以来求助各位!
