Only you can prevent forest fires. But in the near future, there could be a better way to fight them. German researchers have designed a dog-sized, insect-shaped robot that can operate independently to fight forest fires. It's equipped with water tanks, fireproof armor, fire-dousing chemicals, GPS, heat sensors, and other high-tech gizmos. The robot's six legs - it has no wheels - give it stability.
There are no current plans to roll out the design for widespread use. But firefighters and fire experts around the world are investigating ways they can apply this new technology.
