about VEX Robotics, particularly their upgradable entry-level Explorer, which lists for $199. Link to review.
Robotics – perhaps like personal computers a generation ago – are becoming cheaper and more accessible. All sorts of implications, of course, in normal circumstances. But for emergency functions – particularly gathering information with lessened risk – robots cheap enough for local non-profit groups and simple enough to be set up, and repurposed, easily.
