Abstract
The remote excavator tool fastens to a robotic arm on a remotely controlled robotic platform that includes a track drive. The tool uses high speed tilling elements rotating at about 1500 rpm to dig, efficiently, a trench using a small amount of power. The tilling elements are hardened steel, rotating counterclockwise to a conventional tiller. The tilling elements are symmetrically mounted on a polygonal shaft, and include right and left multiple couples of paired facing disks with staggered curved tines, where the tines are thick and have tapered hardened edges. Round brushes are interspaced between couples. The loosen soil is pushed forward and to the sides to help protect the robotic platform and maintain control of the tool especially as the rate of the excavation partially depends on the characteristics of the material being excavated.
