Hitchhiking robot is halfway across Canada

He or she -- it's hard to tell -- is short and friendly, if a little fashion-challenged. The robot employs artificial intelligence, speech recognition, social media and other tools to bum rides from motorists. Deposited last Monday on Highway 102 outside Halifax, hitchBot by Friday had journeyed to just west of Toronto. Its travels are being documented on Twitter, on Instagram and on the robot's website, which charts its progress on a map. The gender-neutral robot was conceived by university researchers David Harris Smith and Frauke Zeller, who view its quest as part performance art, part social experiment.
