It can travel through both vertical pipes and curved pipes to make possible inspection that would be difficult with conventional endoscopes. This mechanism is composed of three units, two novel micro mechanisms called as a planetary wheel mechanism for robot drive, two micro electromagnetic motors and a flexible coupler.展开更多
