Setting private rosparams through a launch file
I have a node where I initialize a set of expected parameters to default values. I am treating the parameters like class member variables. I am now trying to set these parameters through a launch file to but it does not appear to be working. When I set the parameter through a launch file and run rosparam get /some_node_name/value
I get the default value of 0
In node.py
class MyNode:
def __init__(self):
rospy.init_node('my_node')
# Create all expected parameters
rospy.set_param('~number', 0)
In the launch file
<node name='some_node_name' pkg='my_pkg' type='node.py' output='screen'>
<param name='~number' value=10 />
</node>
Am I missing something? Or is this not possible? I was keeping the parameters "private" as I will be launching multiple nodes of the same type, all with different node names

Have you tried not using

in your launch file for the private parameters?Asked by jayess on 2018-08-19 19:19:27 UTC
