The Frugal Feeding Problem: Energy-efficient, multi-robot, multi-place rendezvous
TLDR
We consider the problem of finding an energy-efficient route for a service robot to rendezvous with every member of a heterogeneous team of mobile worker robots, finding it to be at least as hard as the travelling salesman problem. Expand

Energy Efficient Robot Rendezvous
TLDR
We examine the problem of finding a single meeting location for a group of heterogeneous autonomous mobile robots, such that the total system cost of traveling to the rendezvous is minimized. Expand

A Distributed Heuristic for Energy-Efficient Multirobot Multiplace Rendezvous
TLDR
We consider the problem of finding a set of trajectories for a heterogeneous group of mobile robots, such that a single service robot can rendezvous with every other member of the team in a prescribed order. Expand

Distributed Gradient Optimization with Embodied Approximation
TLDR
We present an informal description of a general approach for developing decentralized distributed gradient descent optimization algorithms for teams of embodied agents that need to rearrange their configuration over space and/or time, into some optimal and initially unknown configuration. Expand

MINING CHANGING REGIONS FROM ACCESS- CONSTRAINED DATA SETS: A CLUSTER-EMBEDDED DECISION TREE APPROACH
Change detection is important in many applications. Most of the existing methods have to use at least one of the original data sets to detect changing regions. However, in some importantExpand
Autonomous Sustain and Resupply, Phase 1 Report
Abstract : This report presents our progress to date on the DRDC Autonomous Sustain and Resupply project. We are using the ASR problem as the key motivating problem for the AI and autonomy researchExpand
Using spatial embeddedness and physical embodiment for computation in multi-robot systems
TLDR
We show that a multi-robot system can use physical embodiment and spatial embeddedness as computational resources for two types of problems: a continuous optimization problem of achieving optimal joint robot team configuration, and a combinatorial problem of sorting robots. Expand
