Video has emerged of the moment a hitchhiking robot was attacked in Philadelphia.
HitchBOT was created to see how people would interact with a talking, solar-powered robot as it hitched across the United States, on its own, tracked by a GPS.
The brainchild of Canadian researchers, it had successfully thumbed rides across Canada, Germany and the Netherlands.
Then, on July 17, hitchBOT set out from Boston, bound for San Francisco, with a bucket list of sights to see.
As chronicled on social media, it caught a Red Sox game and visited Times Square, through the kindness of strangers who became friends.
But late last week hitchBOT hitched its last ride. On Saturday, the robot was found in Philadelphia, the City of Brotherly Love, resting in pieces.
Today surveillance video surfaced of the attack, but the robot's creators are not out for vengeance.
"It could have happened anywhere," says creator Dr Frauke Zeller. "We don't really think it has anything to do with Philadelphia."
In a final tweet, hitchBOT said: "My love for humans will never fade."
