日本語は下 I use an iPhone all the time, but I have a problem sometimes... Yes, I cannot reach it in some situation (you know), then missed very important calls. So I tried to build "self moving" iPhone robot that will automatically find me when an iPhone receives a call and I cannot reach to. But still a problem had not been solved. So I tried to build another iPhone robot, which is "Walking"
