2. UW Computer Science Department Traditional Robotics Traditionally, robotics researchers focus on the development of highly capable and expensive robots. Only a few are made. –Predator airplanes With swarm robotics, the emphasis is on having lots of relatively inexpensive robots. –Micro-air vehicles

3. UW Computer Science Department Advantages Swarms of robots are effective: –They can perform tasks that one expensive robot cannot. Swarms are robust: –Even if some robots fail, the swarm can still achieve the task.

4. UW Computer Science Department Goal The UW Distributed Robotics Laboratory serves as an environment for prototyping and demonstration of proof-of-principle for swarm robotics. Our goal is to design methods for enabling groups of robots to perform important real- world tasks…
