Most of the bots we've seen recently have either been targeted at performing human-like tasks or simply too adorable to actually fear, but SRI International's wall-climbing robot is doing its best to put some terror back in the bot game, using something called "electro-adhesion" to cling to nearly any building material and climb with surprising alacrity. Electro-adhesion is apparently relatively low-power, and SRI researchers say that the bots can even climb walls that are covered in dust or other debris. Interesting -- just don't give the thing any cameras or lasers, okay? Video after the break.
