Abstract: An energy-saving transportation tool performing self-horizontal rail laying in multi-terrain conditions performs self-horizontal rail laying through a hydraulic and servo transmission system, to enable a carriage to keep traveling at a uniform speed on horizontal rails. Because without frequently performing actions such as acceleration, deceleration, and braking, the transportation tool needs to overcome only rolling friction to keep uniform motion, energy consumption can be reduced. Support feet of the transportation tool are designed into a bionic hoof shape, and are particularly adapted to special terrains such as mud and swamp. The transportation tool can lay the horizontal rails above an obstacle or shallow water, and can adapt to various special terrains such as shallow water, mud, and swamp. When traveling, the transportation tool can turn as required. The transportation tool is equipped with a lidar for detecting a road surface condition, and has an unmanned driving function.
