Robocup ve USARSIM Dr. Muhammet Balcılar
What is RoboCup? an international research and education initiative an attempt to foster AI and intelligent robotics research by providing a standard problem for this purpose, a soccer game was chosen as the primary domain Why Soccer? Soccer is the world’s game. RoboCup is a task for a team of multiple fast-moving robots under a dynamic environment in order for a robot team to actually play soccer, various technologies must be incorporated, such as: autonomous agents, multi-agent collaboration, strategy acquisition, and real-time reasoning
A New Standard Problem? a standard problem is a clearly-defined, realistic and affordable challenge that can be used to evaluate and compare various algorithms, theories, and architectures Turing proposed chess as a standard problem for AI (because chess is hard) It is proposed that RoboCup should be a new standard problem for intelligent robotics

The chess problem is (virtually) solved and has become “too simple” to spur innovation, whereas RoboCup is cutting-edge:

Competition setting Simulated victims Signs of life: human form, motion, heat, sound, CO2 Signs of life: form, motion, heat, sound, CO 2 THERMAL IMAGE VISUAL IMAGE
AriAnA & AVA A joint team from Iran and Malaysia, AriAnA & AVA use two robots, shown in Figure 4. The left robot is fitted with a gimballed LIDAR supported by two servo motors, and an inclined LIDAR at the front. At the front left and right are TPA81 Devantech thermal sensors, which can be panned by servo motors.
Rescue Virtual Competition USARSim Based on the Unreal game engine (UT2004, Epic Games) Realistic models of USAR environments, robots (Pioneer2 DX, Sony AIBO), and sensors (Laser Range Finder, Color Camera, IMU, Wheel Odometry) Multiple heterogeneous agents can be placed in the simulation environment High fidelity simulation of up to 12 robots
Rescue Virtual Competition Introduction cont. Unreal Client Unreal Server Command Sensor data Sonar Sensor message
Rescue Virtual Competition Performance Metrics (Her sene değişiyor) Victim discovery –Victims are detected by a simplified sensor retuning ID/state depending on distance –Victim ID (10pt), Victim status (20pt), victim location (10pt), additional information (20pt) Self Localization and Mapping (SLAM) –Metric quality (50pt): How close are reported locations to ground truth? –Multi-robot fusion: Bonus for maps generated by multiple robots Exploration –Max. 50pt if exploring the whole area –NEW: Explored areas have to be marked as “cleared” Penalization –Robot-Victim collision (-5pt) –Teleoperation: Division of total score by (1+N) 2 –NEW: One mandatory operator for each team
Rescue Virtual Competition More new features Improved robot models for realistic mobility GeoTIFF format for maps Maps will be overlaid on and compared to ground truth Teams must specify areas “cleared” –Points deducted for victims in “cleared” areas
Rescue Agent Competition Introduction Large scale disaster simulation –Simulators for earthquake, fire, civilians, and traffic –The task is to develop software agents with different roles, that make roads passable (police) extinguish the fires (fire brigades) rescue all civilians (ambulances) –Difference to Soccer Simulation: A challenging Multi-Agent Problem since Agents must cooperate
