Obstacle crossing robot and obstacle crossing method thereof

The invention relates to an obstacle crossing robot and an obstacle crossing method thereof. The obstacle crossing robot comprises a structure module, an induction module and a control system. The structure module comprises a machine body and three sets of walking mechanisms sequentially arranged in the length direction of the machine body. Each of the three sets of walking mechanisms comprises two obstacle crossing devices symmetrically arranged on the two sides of the machine body. Each obstacle crossing device comprises a first drive device arranged on the machine body, a leg support connected with the first drive device, a drive wheel arranged at the other end of the leg support, and a second drive device which is connected with an axle of the drive wheel and provides power for the drive wheel. The induction module is arranged on the machine body. The control system is electrically connected with the induction module and the first drive devices and the second drive devices of the three sets of walking mec
