1. A method of fluid extraction from a formation, comprising:
pumping a liquid downhole into the formation, wherein the liquid comprises at least one fracbot coated in a coating;
dissolving the coating encompassing the fracbot when a predefined temperature is reached downhole, thereby activating the fracbot;
drilling, by the fracbot, a channel connecting a first fracture and a second fracture in the formation, wherein the fracbot drills by vibrational movement; and
extracting the fluid out of the formation via the connected first and second fractures.
