LANdroid Wireless Battle Router and Tank
 

Ever wish that your wireless network could follow you wherever you went? Yeah, so does the US Army. DARPA’s LANdroid is a palm-sized, totally autonomous network router on cute little tank treads. It’s designed to be used in urban environments which have all sorts of inconveniently placed buildings that block more conventional wireless access points. These little guys are actually designed to be disposable; the idea is that they get dropped by advancing troops, whereupon they wander around at about half a meter per second until they find the most effective place to act as a network node. The bots work together to cover “shadowed” and indoor areas, and if one of them gets blown up, the rest will move themselves to keep the network operational.
