"The Autonomous Nano-Technology Swarm (ANTS) is a mission systems architecture for scalable, robust, highly distributed systems" Social insects paradigm. "The generalization arises because current science mission and spacecraft architectures carry several science instruments. Even for the relatively favorable case where the instruments are focussed on related science goals, the operational characteristics of the instruments may lead to unavoidable conflicts. In addition to conflicts with other science instruments, it is common for the needs of the science instrumentation to be somewhat at odds with the more mundane health and safety concerns related to the very functioning and survival of the spacecraft." * Something to trade: needs of the different instruments. + Makes pretty solid argument for autonomous systems far from earth: expensive/impossible communication limited interaction possible * Trade-off wide coverage or high resolution - Very long-term, and "envisioned mission/technology" "Though we have used examples of ANTS as applied to asteroid exploration, the ANTS Architecture is more widely applicable. ANTS should be considered for missions or mission components that ( 1) require large-scale, possibly dynamic, spatial and temporal coverage or other mission functions, (2) involve adverse communication latencies and bandwidths, and (3) do not require immediate human presence and input. We have concentrated on ANTS as applied to science missions where the main mission functions are the cooperative gathering and filtering of data according to a swarm's mission goals. Other missions that may benefit fiom the ANTS approach could include resource extraction, system construction and maintenance, automated logistics and communications, and human mission support."

X Abstract

The proposed Autonomous Nano-technology Swarm (ANTS) is an enabling architecture for human/robotic mission envisaged by NASA's mission for the Human Exploration and Development of Space (HEDS). ANTS design principles draw on successes observed in the realm of social insect colonies, which include task specialization and sociality. ANTS spacecraft act as independent, autonomous agents for specific functions, while cooperating to achieve mission goals. For example, the Prospecting ANTS Mission (PAM) is a long-term mission concept for the 2020-2025 time frame involving individual spacecraft agents that are optimized for specific asteroid prospecting functions. The objective of PAM is to characterize at least one thousand asteroids during each year of operations in the main belt. To achieve this objective, PAM spacecraft, individually and as a group, must achieve a high level of autonomy. This high degree of autonomy opens the possibility of a new kind of interaction between humans and these spacecraft, where human explorers and developers could interact with ANTS enabled resources by communicating high-level goals and data products. Thus ANTS enables new kinds of missions in which human and robotic agents work together to achieve mission goals. In this paper we review and discuss the ANTS architecture in the context of the HEDS mission.
