  • Systems and Methods for Downward Drilling Robotic Systems
    Publication number: 20260251050
    Abstract: Systems and methods for downward drilling robotic systems in accordance with embodiment of the invention are illustrated. One embodiment includes a drilling robot. The robot includes an outer casing, a chassis coupled to the outer casing, and a plurality of wheels. The drilling robot further includes at least one drive motor received at least partially in the chassis and configured to rotatably drive the plurality of wheels on a surface, an autonomous control system configured to control movement of the drilling robot along the surface, and a drilling module coupled to the housing that supports a drill for movement along a movement axis transverse to the surface.
