Networks of Autonomous Unmanned Vehicles Prof. Schwartz Prof. Esfandiari Prof. P. Liu Prof. P. Staznicky
2
Slide Name Research and Development Areas,Autonomous Robot Construction.,Cooperating Mobile Autonomous Robots.,Vision Systems.,Robot Flocking and Swarming,Robot swarms that adapt and learn (game theory and evolution).,Robot teams and learning.
3
Slide Name Autonomous Vehicles Built from low cost robot kit. HandyBoard HC11 controller Bluetooth communication channel. Sonar sensor. Able to control over internet. On board navigation control.
4
Slide Name Robotic Tracking,Activmedia PeopleBot Robot,2 DOF camera –Optical flow-based target detection and verification –Target’s motion is estimated using a particle filter,Laser rangefinder –It is used to determine distance between robot and target
5
Slide Name Robotic Boat,developed by 4 th -year students,The boat can be controlled over a wireless network,User with a PC and a web browser can control the boat from anywhere,The web server is placed on the on-board microcontroller, which has not be done before by others
6
Slide Name Unmanned Aircraft System (UAS) Development,UAS for geophysical surveys is being developed in the Mechanical and aerospace Engineering department (M&AE), with industry partner, an Ottawa company and with support from Systems and Computer Engineering (SCE),UAS has a demanding mission –8-hours endurance –Airspeed between 60 and 100 kts –Low altitude down to 30 ft above terrain; terrain following is required –Sensitive magnetometers are mounted on the wingtips –Magnetic signature of the air vehicle must be minimized
7
Slide Name UAS Development: Status,Air Vehicle prototype is being built,Size: Wing span 16 ft, weight 200 lb, engine power 30 hp,Start of flight testing: spring of 2009,Four research projects are underway, collaboration between M&AE and SCE: –Autonomous operation –Obstacle detection and avoidance –Magnetic signature control –Low-cost non-magnetic airframe
8
Slide Name Cooperative robots and intelligence Robots have own control and navigation algorithms Robots only know their position and others
9
Slide Name Video Processing and Understanding Tracking of video objects
10
Slide Name Networks of Robots and Sensor Swarms
11
Slide Name Robots that follow each other and avoid obstacles
12
Slide Name Vehicles Playing the Evader – Pursuit Game Research Topics Vehicles Learn Each Others Dynamics. Vehicles Adapt Behaviour. Coalition and Team Formation
13
Slide Name Soccer Playing Robots,We are interested in imitating agent behavior that is space and time dependent,RoboCup is a good environment for such exploration Our methodology: 1.Perform data capture from logs generated by existing RoboCup clients 2.Transform the captured data into a spatial knowledge representation format (a scene) 3.Game-time: pick closest (or one of k-closest) captured scene to current one and perform corresponding action,We are interested in imitating agent behavior that is space and time dependent,RoboCup is a good environment for such exploration Our methodology: 1.Perform data capture from logs generated by existing RoboCup clients 2.Transform the captured data into a spatial knowledge representation format (a scene) 3.Game-time: pick closest (or one of k-closest) captured scene to current one and perform corresponding action

Slide Name Robots Learning How to Play Soccer
15
Slide Name Scene Recognition,Find best match(es) between current situation and stored scenes (k- nearest-neighbor search),Perform associated action -> accuracy of the distance calculation function between two scenes is crucial,Find best match(es) between current situation and stored scenes (k- nearest-neighbor search),Perform associated action -> accuracy of the distance calculation function between two scenes is crucial “What should I do in this situation?” “What did the observed agent do when faced with a situation like this?”
16
Slide Name The Robots Have Learned the Game
17
Slide Name Limitations and Future Work,Short term –consider object velocity; –weigh the importance of an object based on its proximity to the player; –scene prototyping to reduce duplication and introduce more scene variation; (done!) –CBR-style adaptation of the action; –automatic weight determination is very time consuming: more tests required here. (done!),Long term –Need to take into account state and context-based behavior:,non-visual info: body state, game state...,actions as part of a plan or succession of scenes –a clue: two similar scenes leading to different actions –might need to remember and backtrack to previous scene(s) –Higher-level representation for scenes,conversion to spatial and/or temporal logic?
18
Slide Name Multiple Robots
19
Slide Name Swarm Intelligence and Personality Evolution,Game Theory, Coalition formation.,Evolutionary Game Theory.,Learning (fuzzy, adaptive, genetic).,Personality Traits.
20
