ABSTRACT:
Disclosed is a novel autonomous excavating apparatus capable of solving conventional problems. The autonomous excavating apparatus comprises an apparatus body including a lower body101formed in a cylindrical shape and combined with a conical-shaped lower end, and a spiral blade102provided on an outer peripheral surface of the lower body101in the form of a right-handed screw. The lower body101has an internal space provided with a wheel103which has a rotary shaft104rotatably supported relative to the lower body101through bearings105, 106. A motor108is fixed to the lower body101at a position above the wheel103, and an output shaft of the motor is coaxially connected to the rotary shaft104. Thus, the motor108can drivingly rotate the wheel103relative to the lower body101.
