Open another terminal, if you type rostopic list , you’ll see there are 2 cmd_vel topics for the robots. The simplest way to control them is with the teleop_twist. We can run it and remap the cmd_vel with the robot you want to control. For example rosrun teleop_twist_keyboard tel...
After runningrosrun teleop_twist_keyboard teleop_twist_keyboard.pyyou can easily move the robot using the keyboard. So that is the post for today. You can also find a live version of this post on our YouTube channel in the link below. Also, please consider subscribing to our channel if ...
<nodepkg="turtlesim"type="turtle_teleop_key"name="myTurtleContro"output="screen"/> </launch> 1. 2. 3. 4. 5. 6. 7. 接着我们启动launch,并查看topic列表看是否有被重命名: source 1. 2.3、launch文件标签之include include标签用于将另一个 xml 格式的 launch 文件导入到当前文件。
