Robots and duelling swimmers

Our foreign bureaus are back in action for another great video featuring cool gadgets from around the globe. CNET Asia takes to the streets with a pair of PC speakers. While they may look ordinary, they double as a mini-accordion and help a busker spread the Rickrolling prank. The French office looks at a smart phone that can receive digital TV, while our US representative rounds things off with a robot inspired by a snake that's helping with medical procedures and injured soldiers.
