This “Heineken Bot” sports Heineken’s green colors and was made by the folks at Middlesex University. The beer-bot was recently shown off at the Kinetica Art Fair in London, where it kept humans inebriated and topped off.
If a human moves their hand above its sonar-sensing head, and then place a cup in its holder they are rewarded with beer. Is there any better reward? No. No there is not.
