A "hitchhiking, tweeting, and trivia-loving robot" named hitchBOT will soon embark on a coast-to-coast, 3871-mile trek across Canada. It was initially conceived by Dr. David Harris Smith and Dr. Frauke Zeller as a collaborative art project. Armed with 3G and Wi-Fi connectivity, hitchBOT will be capable of accessing Wikipedia, interacting with social media, and both recognizing and processing speech. One thing it can't do is move: hitchBOT is largely incapable of independent motion, and must rely on charm to secure rides from Halifax, Nova Scotia to Victoria, British Columbia.
As the Pentagon expands its use of robots on the battlefield and its investments in developing robot technology, a movement to ban the use of autonomous robots on the battlefield is growing. Those who decry the use of robots argue that removing the human element from warfare would remove all moral judgment; robot soldiers would be unfeeling killing machines.
One researcher, however, believes just the opposite. He argues that robot soldiers would make warfare more ethical, not less.
