Mapped robots

There are some robots with some of their nodes already mapped. This way you can substitute the line

~/catkin_ws/src$ git clone https://github.com/alf767443/node_monitoring.git

as described in the subtopics below:

Topics (topics.py)

This file is a configuration file in which are described the topics that will be subscribed (topic), the message type (msg), the waiting time between captures (sleep), the data manipulation function (callback), storage information (dataSource, dataBase, collection).

Structure

{
'topic'   : --The topic name,
'msg'     : --The type of message
'sleep'   : --Sample time [optional, 1]
'callback': --Callback function [optional, None]
'dataPath': {
	'dataSource': --Name of data source in MongoDB [optional, config.DATASOURCE]
	'dataBase'  : --Name of data base in MongoDB [optional, config.DATALAKE]
	'collection': --Name of collection in MongoDB [optional, topic name]
	}
}

Configurations (config.py)

This file contains the settings of values robot name (ROBOT_NAME), database (DATALAKE), MongoDB server address (CLIENT) and buffer path (PATH).

Structure

PATH        = os.path.expanduser('~')+'/tempData/'
ROBOT_NAME  = 'New Robot'
DATALAKE    = "CeDRI_New_Robot"
CLIENT      = pymongo.MongoClient('mongodb://192.168.217.183:27017/')
