Robots might not be fighting wars by themselves yet, but they're doing their part among the support ranks in the battlefied. As equipment such as pocket-sizedbecome increasingly common, other types of mobile equipment aren't far behind.
DARPA's "LANdroid" prototype, for instance, is a wireless network router mounted on treads that looks like a tiny tank. Like the ultra-portable spy bots, the palm-sized device is designed to be dropped by Army troops in the field, then autonomously find the best spot to station itself as a network hub, according to OhGizmo.
It's being developed with military uses in mind but, until the world is blanketed with Wi-Fi or WiMax, we could use one of these little guys too.
