Contents • Introduction • Coordination vs. Cooperation ?! • MRS Taxonomy • Immune Systems • Proposed Approach • Summary
Introduction • To propose an immune-inspired approach on cooperation. • To establish an adaptive cooperation algorithm in heterogeneous robot teams. • To determine the effect of the applied approach in terms of efficiency in cooperation. Investigate the implementation of immune-based algorithm in achieving adaptive cooperation in a group of heterogeneous robots.
Coordination: "cooperation in which the actions performed by each robotic agents in such a way that the whole ends up being a coherent and high-performance operation" (Ferber, 1999) Cooperation: "robots that operate together to perform some global task" (Noreils, 1993) Coordination/Cooperation
MRS Taxonomy • System Dimensions • system features that influence team development Coordination Dimensions type of coordination that is achieved in the MRS
System Dimensions Communication Direct communication Indirect communication (Stigmergy) can also be in more detail, i.e. topology, range & bandwidth (Dudek et al., 1996) • Team Composition • Homogeneous • Heterogeneous • or using Social Entropy (Balch, 1997)
System Dimensions System Architecture Deliberative - overall long term plan Reactive - individual plan by each robot Team Size explicitly consider dealing with many robots don't consider or the number of robots
Basic Immune Activation & Effector Phases (Nosssal, 1993)
Proposed Approach Utilize Immune System: with Memory able to retain previous state/action to make the next action Advantage: more efficient with Swarm algorithm able to adapt in wider environment Advantage: more robust
Summary Studying the implementation of immune-based algorithm in achieving adaptive cooperation in heterogeneous multirobot systems.

Multi-Robot Task Allocation The taxonomy of MRTA can be considered as a more detailed Strongly-Coordinated type: Robot - single-task (ST) vs. multi-task (MT) Task - single-robot (SR) vs. multi-robot (MR) Assignment - instantaneous assignment (IA) vs. time-extended assignment (TA)
Social Entropy Het(R) is the function that calculates the heterogeneity of the robots society R, and p calculates the propotion of robots in the corresponding subgroup C to R Partition the robots into several groups, where all members of a given group have similar behaviours.
