    Although most hitchhikers (搭便车的人) are people, passers-by tend to ignore them because they are cautious about giving rides to strangers. But what will they do if they come across a hitchhiking robot? Will they take it to its destination or will they just leave the helpless machine by the wayside?

That is the answer Canadian professors, David Harris Smith and Frauke Zeller, who study the relationship between humans and technology, are seeking for after they came up with the idea of building a hitchhiking robot.

HitchBOT is built with cheap household items. Thanks to a PC tablet, GPS tracker and camera, hitchBOT not only can send its thoughts and pictures to the general public, but also can answer general questions and keep drivers entertained with small talks. The smart robot is even able to quote interesting facts about the areas it has passed through.

Not surprisingly, many people are doubtful about hitchBOT’s ability. Most people think the cute robot will be damaged by someone. Actually, they are all wrong. The robot hitchhiked all the way from Halifax, Nova Scotia, to Victoria, British Columbia, a distance of 3,700 miles. It was first picked up on July 27th by an elderly couple. It not only reached its destination on August 21st, but also had some amazing adventures along the way. It visited national parks, went fishing, went camping, and even attended a wedding where it experienced its first dance and interrupted the bride’s speech.

In addition to helping it get to its destination, its Canadian fans have gone out to ensure its safety from covering the robot with a plastic cape (披肩) to help keep it dry to ensuring that it stays healthy with motor oil.
