Collector Service

model: QmUB6ajZTLLMZg7re1v4hw44aoG8HDQDHr9JyujU264Aw2

This agent is responsible for collecting data from renewable energy source and publishing a demand message.

Have a look at the Issuing service to see the second part of the project.

Nodes

There are two nodes:

• applicant - packs all the collected data to objective and sends a demand message to issue new certificates
• collector - continuously collects the data from the solar panel

Services

• publish_demand - creates a demand message and publishes to Robonomics network
• get_objective - packs all the data to a rosbag file, publishes to IPFS network and returns the IPFS hash of the file

Build

nix build -f release.nix

Run

roslaunch collector_agent applicant.launch db_url_config:=./db_url.config rest_api_key_config:=./rest_api_key.config

Where

• db_url_config - a file contains a string that indicates database dialect and connection arguments in SQLAlchemy form
• rest_api_key_config - a file contains a string that indicates a username/password for REST API server of energy source

It's possible to specify a table name for the database. By default it's solar

Proxy

There is a small proxy server called proxy.py. It's purpose is to call ROS services from POST requests. The default port is 8899

• / - calls publish_demand service
• /get_objective - calls get_objective service
