Mars EVA Computing Environment

• Project Introduction
• Mark Smith
• ideapod_at_yahoo.com.au

2
Mars Society Australia

• Not for Profit Society, one part of global mars
  society. The goals are
• Public and outreach programs to promote mars
  science and exploration
• Encouraging Government endorsement and funding of
  mars exploration program
• Support of privately funded mars exploration
• Promotion and support of australian contributions
  toward mars exploration through education,
  industry, government and individuals.
• Operation Red Centre to build Rover, Hab, and
  Suit.
• People from Uni's in Perth, ANU, Uni NSW and QLD
  involved in various aspects of projects

Mars Skin

• Mars Skin is the project to develop a Mechanical
  Counter Pressure (MCP) Suit.
• Led by James Waldie RMIT PhD student
• Requires a method of logging data captured during
  the mission.
• ExOne planned for 'Version 2' Mars Skin.

4
Data Logger History

• Mars Society Canada Produced a Data Logger
• Integrated with MarsSkin in Utah(ExOne).
• Technologies
• Linux
• 'C'
• PC104 platform
• Custom 4x4 keypad display for user input
• Logs to hard disk for later evaluation

5
Why Yet Another Data Logger?

• Not just a data logger think of the wider
  problem
• What are we trying to do when we go to mars and
  do an EVA?
• Explore
• gain scientific understanding
• collaboratively work through the problem
• Co-ordinate our activities

6
Mars EVA Computing Environment

• Develop software system
• Plan Missions EVA's
• Execute and Monitor the Plan
• Analyse the results afterwards
• Let's take an example

7
Features Planning

• Plan the Rover Route from Hab
• EVA Points along the way.
• Drill to EVA's, and plan eva route
• Plan resources
• Equipment
• Personnel
• Suits
• Rover

Features Execution 2

• Video, Data logged to disk, but also streamed to
  Rover
• Rover Operator can be in conversation
• Command of robots through same software

GPS
Vital Signs
Suit Data
External Instrument
Suit 1..n
10
Features Monitoring

• GPS tracking of each suit through planned route
  of EVA.
• Events logged by EVA participants, causes
  annotation to data stream.
• Event summary sent through to any hab, or
  terrestrial monitors.
• Aliens 2 type video/vitals display

To earth?
Event Summary to HAB Monitor
Event Data thru 802.11b
Or, if proximity allows thru 802.11b
11
Features Analysis

• Post Mission/EVA, events punctuate collated
  data.
• Event data can be extracted for analysis.
• Mission Results stored in Global Mission Store

12
How?

• Technology Search
• perl, jxta, palm technologies, C streaming
  libs, SIP phones
• Decided
• Windows/Linux with 802.11b Wireless Network
• Java high level language detailed platform
• Jini Spontaneous Network technology
• JMF Java Media Framework media capture
  streaming.
• JSP Java Server Pages GUI for
  planning/monitoring

13
Systems Overview

• Main Points Wireless LAN for opportunistic
  connection
• Jini Services
• Global Mission Controller
• Global Mission Store
• Local Mission Controller

14
RTP Streaming for Voice Data
15
JINI

• Spontaneous services perfect for Mars!
• Combined with Wireless networking
• Ubiquitious, proximity based service and data
  provision

Registrar
2. Asks for LMC, gets service Object
1. Registers LMC with Registrar
Local Mission Controller
EVA Participant
3. Makes use of LMC service
16
Project Status

• Documentation Begun
• Model in ArgoUML containing
• High level use cases
• Mission store hab/suit/rover servers begun.
• Mission/planning objects services
• Rover UI is furthest advanced, shows not much,
  and trying to integrate with JINI
• JMF used for Audio Streams (not yet operational)
• Code available on source forge.
• Susan Smith in Sydney working on persistence for
  mission store.
