The invention provides a self-balancing storage robot for dangerous places, comprising a self-balancing structure, the self-balancing structure includes a bottom plate, a rotating center column, a balance adjustment group and a balance plate; the middle part of the surface of the bottom plate is connected by the rotating center column and the middle part of the balance plate , the top of the rotating center column and the middle of the balance plate are hinged; the surface of the bottom plate is connected to the balance plate through a plurality of balance adjustment groups. The balance adjustment group includes a motor seat, a motor, a ball screw pair, a connecting seat and an adjustment column, and the motor is arranged through the motor seat. On the surface of the bottom plate, the connecting seat is connected with the motor coupling through the ball screw pair, one end of the adjusting column is hinged with the connecting seat, and the other end of the adjusting column is hinged with the balance plate. When the motor coupling rotates, the adjusting column is driven to rotate. Using this scheme, by adjusting the angle of the balance plate relative to the horizontal in any direction, to ensure that the material is stationary relative to the support surface, that is, to ensure the safety of the material, especially when transporting dangerous goods in a military product manufacturing plant, which has important safety significance.
