Equivalent sample in Dora for ROS2 parameters

[bobd988]

Here is description of ROS parameters

Parameters in ROS are associated with individual nodes. Parameters are used to configure nodes at startup (and during runtime), without changing the code. The lifetime of a parameter is tied to the lifetime of the node (though the node could implement some sort of persistence to reload values after restart).

Parameters are addressed by node name, node namespace, parameter name, and parameter namespace.

Each parameter consists of a key, a value, and a descriptor. The key is a string and the value is one of the following types: bool, int64, float64, string, byte[], bool[], int64[], float64[] or string[]. By default all descriptors are empty, but can contain parameter descriptions, value ranges, type information, and additional constraints.
