Human Simulation GUI for ECLSS

Human Simulation GUI for ECLSS

The Human Simulation GUI is a PyQt-based graphical interface designed to simulate astronaut life support interactions within a closed-loop Environmental Control and Life Support System (ECLSS) aboard a spacecraft or station. This GUI drives crew activity logic and interfaces with underlying ROS 2 action and service servers for the following systems:

Air Revitalisation System (ARS)
Water Recovery System (WRS)
Oxygen Generation System (OGS)

Modes of Operation

Upon launch, the GUI allows selection of one of three simulation modes:

1. User Mode

Minimal configuration
Suitable for general demonstrations
Sends standard goals to life support systems

2. Developer Mode

Allows parameter tuning
Logs additional debug output
Exposes underlying system behavior

3. Astronaut Mode

Simulates a full crew’s daily physiological needs
Evaluates system response across multiple days and events
Includes failure conditions and recovery

System Architecture

Node: `crew_simulation_node`

This node powers the GUI and simulates crew metabolic demands by:

Sending action goals to ARS and WRS
Calling services for oxygen and water from OGS and WRS
Subscribing to O₂ and water reserve levels to decide when to trigger actions

Topics/Subscribers

Topic	Message Type	Purpose
`/o2_storage`	`std_msgs/Float64`	Receives O₂ reserve updates
`/wrs/product_water_reserve`	`std_msgs/Float64`	Receives water tank status

Action Clients

Action	Purpose
`air_revitalisation`	Removes CO₂ and contaminants
`water_recovery_systems`	Purifies urine into usable water

Service Clients

Service	Purpose
`ogs/request_o2`	Requests oxygen from OGS
`wrs/product_water_request`	Requests drinking water

Execution Instructions

1. Build the Workspace

colcon build --packages-select space_station_eclss
source install/setup.bash

2. Launch Full ECLSS Simulation with GUI

ros2 launch space_station_eclss eclss.launch.py

This will launch:

The Human Simulation GUI
ARS, WRS, and OGS system nodes
All required ROS 2 interfaces for simulation

GUI Overview

Image Banner: Displays an SSOS image if available
Mode Selector: Buttons for User, Developer, and Astronaut modes
Log Box: Shows simulation output, status messages, and feedback
Sim Controller (per mode): Each mode opens a specialized window with parameter controls and real-time simulation feedback
