Origins of MA Design: Historical & Analog Missions Apollo’s CapCom, a virtual assistant on the moon Biologists navigating in Haughton Crater (1999) Crew struggles with GPS during MDRS5 simulation
WILLIAM J. CLANCEY, PI & MAARTEN SIERHUIS, PROJECT MANAGER Human-Systems Integration Device Control: sensors/ instruments, tools, robots, systems (life, power, computing) Data Flow: Queue, sample, store, associate, share, display Work Management: Monitor, advise (loc, time, activity), interpret, alert Voice-Commanded Toolkit
Technical Features Multi-Agent System –Functional & personal –Distributed control & data- processing Wireless Computing –Platform independent –Tested over 5 km Modular Configurations –Plug & play (Java API) –E.g., 5 robots, 3 cameras, 5 biosensors, 2 computer sensors, dGPS, headsets Astronaut Backpack System
Mobile Agents Utah Field Test 2005 50 Participants; 17 days; 2 NASA centers & several universities Multi-robot, auto-recon, & freeform exploration scenarios More proactive ERA design More proactive RST More robust, faster, reusable agent system (> 60) Improved alerts, queries (> 90), & auto-associations EVA crew less reliant on HabCom crew member Geologists Exploring with Mobile Agents
New MA’05 Operations Interacting with the robots to determine their status: Whom are you following? Do you still have comms? Establish dependence on robot relay: Boudreaux, join me. Contextual robot move commands: Come here. Go there. Directed photos: Take a picture of work site 5. Astronaut naming of “work stations" (default 1 m areas) within work sites: Call this location 9 with a radius of 5 m. Astronauts can refer to names teammates create. Requesting locations and navigation information: Where is work site 5? Where am I? List all the locations near work site 6. Where is the next activity?

Experiment Observations (Day 5 EVA 2 Beyond Pooh’s Corner) Enables independent, simultaneous work, which geologists prefer But agents talk over astro conversations –Astro cannot hear that partner is listening to agent –Astro interleaves response with conversation –Results in “What did you say?” Ready for next level: Voice loop management, alternative feedback, protocol personalization Overall: System Responsive and processed data appropriately
Example Good Results Where is Boudreaux? Boudreaux, stop. How much time is left? What is the current activity? (Astro2) Where is Astronaut 1? Where am I? Warning: Time exceeded. Sorry: Can’t do that. Warning: Battery is low.
Some Not So Good Results Misunderstood “okay” as volume change command. Boudreaux is 1.1794857 E 7 meters North-East-East from you. Thibodeaux, join me (OK) Astro2 remarks to partner that join command worked; Astro 1 is listening to his agent and didn’t understand; Astro2 repeats what she said, but agent hears this as the command itself!
