OK. so this thing can follow a marked trail. Pretty cool, but robots have been doing that since the early 80's if not late seventies in home kits. Now imagine if it could follow a trail of say, blood, using this. No more bloodhounds, sure, but an autonomous robot that can see both footprints (via IR) and the blood trail left by a fleeing assailant would be a  huge boon for law enforcement.
