Those rascals at Middlesex University have outdone themselves with what they're calling a "Heineken Bot", a beer serving robot. It takes a pre-programmed path along the bar and if you hover your hand over it's sonar-sensing head and place your sad, empty cup in its grasp it will dispense the sweet nectar to you. Brilliant! Suck on that R2D2, you useless tank of bolts.
It does my heart good to see great minds actually getting put to use on things that can be useful for this world.
