2. A. Kleiner, Albert-Ludwigs-Universität FreiburgRoboCup Rescue - Austrian RoboCup Workshop2 Motivation The time problem after an incident

3. A. Kleiner, Albert-Ludwigs-Universität FreiburgRoboCup Rescue - Austrian RoboCup Workshop3 Motivation Where is the benefit from robotics technology? After a disaster many places are unreachable for humans Robots can access places humans cant (e.g. small holes or spaces under the floor) Robots can send video and thermo images from hazardous places Destroyed infrastructure: Problem of self- localization Quality of disaster response strongly depends on information, such as maps with victim locations Tom Haus (firemen at 9/11): We need a tracking system that tells us where we are, where we have been, and where we have to go to Technology from Robotics can be deployed for information gathering and world modeling Autonomous systems: Reduction of cognitive load

4. A. Kleiner, Albert-Ludwigs-Universität FreiburgRoboCup Rescue - Austrian RoboCup Workshop4 Rescue Robot League Research Challenges High degree of mobility Simultaneous Localization And Mapping (SLAM) Victim detection Autonomy!

5. A. Kleiner, Albert-Ludwigs-Universität FreiburgRoboCup Rescue - Austrian RoboCup Workshop5 Rescue Robot League Build robots that are ready to leave the lab! You might be too small …… or you might be too big

6. A. Kleiner, Albert-Ludwigs-Universität FreiburgRoboCup Rescue - Austrian RoboCup Workshop6 Rescue Robot League Goals and directions Cooperative development with simulation league Step-wise increase of difficulty (e.g. like golf courses) Building of standards for mapping and data exchange between heterogeneous units Towards mixed-initiative solutions, i.e. humans and robots build one team for efficient disaster response

7. A. Kleiner, Albert-Ludwigs-Universität FreiburgRoboCup Rescue - Austrian RoboCup Workshop7 Competition setting Three types of arenas YELLOW ARENA RANDOM MAZE PITCH & ROLL RAMP FLOORING (10°) DIRECTIONAL VICTIM BOXES (FOR AUTONOMOUS ROBOTS) ORANGE ARENA PITCH & ROLL RAMP FLOORING (10°, 15°) HALF CUBIC STEPFIELDS CONFINED SPACES (UNDER ELEVATED FLOORS) VICTIM BOXES WITH HOLES RED ARENA FULL CUBIC STEPFIELDS STAIRS (40°, 20CM RISERS) RAMP (45° WITH CARPET) PIPE STEPS (20CM) DIRECTIONAL VICTIM BOXES REGIONAL/PRELIMINARY ARENAS SHOWN, CHAMPIONSHIP ARENAS WILL BE TWICE THIS SIZE

9. A. Kleiner, Albert-Ludwigs-Universität FreiburgRoboCup Rescue - Austrian RoboCup Workshop9 Competition setting Rules at a glance GeoTIFF map formats will be used to allow comparison of maps to ground truth arena configurations. Best-In-Class awards for autonomy and mobility will be given to robots that find the most victims in the Yellow and Red arenas respectively over all missions. Random mazes with non-flat flooring Stepfield pallets (Orange: half-cubic, Red: full-cubic) Stairs (40°, 20cm riser, 25cm tread depth) Ramp (45° to test torque and center of gravity) Confined spaces (ceiling blocks under elevated floors) Visual acuity (tumbling E eye charts, hazmat labels) Directed perception boxes with victims/targets inside Simulated Victims: 4 per arena, 12 total Signs of life: form, heat, motion, sound, and/or CO2

10. A. Kleiner, Albert-Ludwigs-Universität FreiburgRoboCup Rescue - Austrian RoboCup Workshop10 Competition setting Rules at a glance II (Missions) 15/20/25 minute missions include robot placement at the start point and operator station setup. Each team is responsible for making sure victims are functional (heat, batteries, tags) prior to their mission start. Teams are allowed one operator during missions. Start points will be in the Yellow arena with all robots facing the same direction (north on your map). Yellow arena victims can be scored only by robots with autonomous navigation and victim identification. Operators may take over control at any time to move into the Orange and Red arenas but must return to the start point to resume autonomous searches. Teleoperative robots can only score Orange or Red arena victims, which are placed on both sides of the Yellow arena to encourage complete mapping.

20. A. Kleiner, Albert-Ludwigs-Universität FreiburgRoboCup Rescue - Austrian RoboCup Workshop20 Rescue Virtual Competition RRFreiburg solution at RoboCup06 Basic Idea: RFID Technology-based Exploration Robots generate local grid maps, generated from Laser Range data A* based planning on local grid Each robot distributes autonomously RFID tags and counts locally in the memory of tags the relative locations already visited If in perception range, robots receive the data of tags and optimize their search by avoiding frequently visited places Extension: Global planner that resets the local search if beneficial Cheap computation on each robot due to a local world model Locations are stored relatively to the tag, hence do not suffer under positioning errors Efficient coordination without need for communication
