Automatic track smoothness detecting robot

The invention belongs to the field of a technique associated with track smoothness detection, and discloses an automatic track smoothness detecting robot. The automatic track smoothness detecting robot comprises a housing, four supporting assemblies, a driving wheel, a control circuit board, a distance sensor and a tilt sensor, wherein the driving wheel is partially accommodated in the housing; the supporting assemblies are connected to the outer side of the housing; the control circuit board, the distance sensor and the tilt sensor are arranged at intervals on the top wall of the housing andaccommodated in the housing; and the distance sensor and the tilt sensor are separately and electrically connected to the control circuit board. The automatic track smoothness detecting robot is enabled to be in a walking mode on the road or a track detecting mode through the rotation of the supporting assemblies. The automatic track smoothness detecting robot disclosed by the invention is simplein structure, low in cost,
