2019-01-18 00:32:19 -0600 marked best answer ROS2 diff between node and component

Hi all,

what is the difference between node and component? As per my understanding and demo example of composition, component is also similar to node.

I also tried the simple example to add simple node(which has been created in class and loaded compile time) in the executor. But I am not able to understand the advantage of component over node?

Thanks in advance!!

Thanks all for the response

2019-01-04 13:30:07 -0600 marked best answer Min and max value with ROS2 Parameter

Hi Everyone,

The dynamic reconfigure is not available in ROS2, and its replacement Parameter feature is used. With ROS, .cfg files are used, where parameter's value, min , max and other details can be given. With ROS2, I tried to set parameter with value and its working fine, but is there a way to set min and max value for that parameter? e.g. of .cfg

gen.add ("min_x", double_t, 0, "X coordinate of the minimum point of the box.", -1, -1000, 1000)

Thanks.

Hi ,

I am aware of simple parameters defining in yaml in ros2 but seeking some help to convert below into ros2 yaml . Please let me know if anyone had handled such type of yaml.

TransferFunction:

    type: filters/MultiChannelTransferFunctionFilterDouble
    params:
      a: [1.0, -1.760041880343169, 1.182893262037831]

2018-12-06 00:18:27 -0600 marked best answer ROS2- passing arguments with launch.py file not working

Hi Folks,

I am trying to launch nodes with launch.py in ros2. Nodes are getting launched but I am facing issue with arguments passing.

My Code snippet:

launch_ros.actions.Node(
            package='tf2_ros', node_executable='static_transform_publisher',node_name='bl_imu', output='screen',
            #arguments=['-0.07' '0' '0' '3.14159' '0' '0' 'base_link' 'laser' '100']),         
            #arguments=['--x','-0.07', '--y', '0', '--z', '0', '--qx', '3.14159', '--qy', '0', '--qz' ,'0', '--qw','1.570796327','--      #frame_id','base_link','--child_frame_id','imu_link']),

I would like to pass arguments to this node static_transform_publisher.

I tried above two ways but getting error with this specific node.

[ERROR] []: static_transform_publisher exited due to not having the right number of arguments
A command line utility for manually sending a transform.
Usage: static_transform_publisher x y z qx qy qz qw frame_id child_frame_id 
OR 
Usage: static_transform_publisher x y z yaw pitch roll frame_id child_frame_id 
[ERROR] [launch]: process[static_transform_publisher-1] process has died [pid 7074, exit code 255, cmd '/opt/ros/bouncy/lib/tf2_ros/static_transform_publisher __node:=bl_imu'].

Please let me know if anybody has tried this or any suggestions.

Thanks, Poonam
