Emergent Task Allocation for Mobile Robots Nuzhet Atay Doctoral Student Seminar Advisor : Burchan Bayazit

Slide 2

Motivation Given an obscure domain and a swarm of portable robots Achieve a few objectives under an arrangement of imperatives Explore the earth Regions of interest Dynamic Unpredictable Spread or psychologist Obstacles Real-life situations Nuzhet Atay

Slide 3

Robotic Systems Heterogeneous robots with constrained Speed Sensing range Communication run Multiple robot coordination Task designation Goal: Optimum task of robots Nuzhet Atay

Slide 4

Planning and Task Allocation Task Distribution Task Distribution Multi-robot frameworks require productive and exact arranging Global ideal arrangements are costly correspondence overhead arranging time Our Solution: A developing methodology Emergent: Solution results from cooperations of robots Local estimation to worldwide ideal Low cost and plausible progressively Nuzhet Atay

Slide 5

Outline Problem Definition Model Centralized (Global Optimal) Solution Emergent Approach Comparison of two strategies Experimental Results Conclusion Nuzhet Atay

Slide 6

Problem Definition Objective is to dole out robots to Cover areas of interest Provide correspondence between all robots Control most extreme aggregate surface Explore new districts We can characterize this issue as a streamlining issue Given the robot data and environment properties What is every robot\'s optimal next step? Nuzhet Atay

Slide 7

Model Robots Constant correspondence and detecting range Limited rate Regions of interest Targets that should be followed by the robots Several robots might be required Input: Information about the robots and the earth Expected target positions after n steps Output Optimum areas of robots Nuzhet Atay

Slide 8

Centralized Solution Task Assignment Information Collection Problem is characterized as a blended whole number straight program Non-direct limitations Flexible Easy to modify Objective: amplify Target Coverage Communication Area Coverage Exploration R 7 T 3 R 8 R 9 R 6 T 1 R 4 R 5 R 3 T 2 R 1 R 2 Central Server Task Allocation is Determined Nuzhet Atay

Slide 9

Target Coverage Each robot has a detecting range Each objective has a scope prerequisite An objective is secured Necessary number of robots has the objective in detecting range Nuzhet Atay

Slide 10

Communication Two robots can convey If they are inside correspondence scope of each other There is a progression of robots that can give correspondence Nuzhet Atay

Slide 11

Area Coverage Maximum zone scope is gotten Sensor cover is minimized Nuzhet Atay

Slide 12

Exploration Robots store the spots they have gone to Each robot tries to find itself outside the investigated district Nuzhet Atay

Slide 13

Optimum Distribution Sample appropriation for augmenting Target scope Communication Area scope Nuzhet Atay

Slide 14

Additional Constraints Environment impediments Convex Partitioned into raised deterrents Convex box encompassing the hindrance Nuzhet Atay

Slide 15

Problems of Global Approach Solution is not practical with huge number of robots Solving blended whole number direct program is NP-Hard Central server Too much information exchange Our answer: Solve little nearby issues Integrate to surmised ideal arrangement Advantage is to maintain a strategic distance from Communication overhead Exponential calculation time Nuzhet Atay

Slide 16

Emergent Task Allocation Find a Solution with Local Information Sharing Robots find ideal arrangements with nearby data Each robot has distinctive data about Robots in nature Targets to be followed Environment properties Solutions are diverse Independent problematic answers for discover better arrangement, robots Exchange data Recompute their answers Final result relies on upon Information content Number of emphasess T 3 R 7 R 8 R 9 R 6 T 1 R 4 R 5 R 3 T 2 R 1 R 2 Recompute Solution with Updated Information Nuzhet Atay

Slide 17

Intentions Robots send their proposed areas to neighbors Each robot accept these areas are last Finds its ideal area Nuzhet Atay

Slide 18

Directives Robots send expected areas of neighbors Each robot picks the best among them Nuzhet Atay

Slide 19

Intentions and Directives Robots send both their and neighbors registered areas Each robot finds the best area utilizing choices Nuzhet Atay

Slide 20

Intentions, Directives and Target Robots send Their and their neighbors\' areas Possible target assignments Each robot Decides an objective task Finds the best area utilizing alternatives Nuzhet Atay

Slide 21

Comparison of Global and Emergent methodology is more effective Computation Communication Approximate answer for worldwide ideal Nuzhet Atay

Slide 22

Experiments How well developing performs? Correlation with worldwide Experiment situation 8 robots 6 targets 3 hindrances How adaptable is the emanant? 20 robots – 10 targets 30 robots – 15 targets Nuzhet Atay

Slide 23

Solution - Global Nuzhet Atay

Slide 24

Solution - Emergent Nuzhet Atay

Slide 25

Comparison Solution quality is similar # of Targets Covered at Each Step Nuzhet Atay

Slide 26

Evaluation Emergent methodology is 400 times speedier than worldwide methodology Solution Time Nuzhet Atay

Slide 27

Scalability Execution time stays consistent with bigger systems Nuzhet Atay

Slide 28

Conclusion Planning structure for multi-robot errand designation Low correspondence cost and appropriate for continuous applications 400 times quicker than the worldwide ideal arrangement Comparable arrangement Future work: Different transaction techniques Implementation on genuine robots Different utility capacities Nuzhet Atay

Slide 29

Questions Motion Planning Group http://www.cse.wustl.edu/~bayazit ? Nuzhet Atay

Slide 30

Convergence ETA ways to deal with CGO after limited number of steps Observation: If all robots locate the same arrangement, then this arrangement is the same as CGO At every stride Robots discover an answer Exchange data and arrange Assuming all state data is shared Robots will have data about other robots\' perspectives After p steps All robots have the same data and locate the same arrangement Nuzhet Atay
