As far as hitchhikers go, this one looks harmless enough. He or she -- it's hard to tell -- is short and friendly, if a little fashion-challenged.
Get him talking, however, and he won't shut up.
Meet hitchBOT, a talking, tweeting, bucket-bodied Canadian robot that's hitchhiking west from Halifax, Nova Scotia, to Victoria, British Columbia -- a journey of nearly 4,000 miles. The robot employs artificial intelligence, speech recognition, social media and other tools to bum rides from motorists.
