1. An on-board control system for a programmed wellbore drone, the system comprising:
at least one control interface for generating a control command adapted to control the wellbore drone,
wherein the wellbore drone comprises a wellbore tool configured to perform at least one action within a wellbore based on the control command,
the wellbore drone further comprises:
an internal power source connected to the wellbore tool and the on-board control system, wherein the internal power source is configured to be inactive to the wellbore tool and the on-board control system until the wellbore drone is deployed into the wellbore and one or more power trigger events occur,
the one or more power trigger events comprise:
matching of at least one of a location of the wellbore drone, a temperature measured by the wellbore drone and a pressure measured by the wellbore drone to a corresponding predetermined value; and
receiving a mechanical force or an electromagnetic force provided from one or more markers placed within the wellbore, so that the mechanical force or the electromagnetic force activates the internal power source or a power connection output from the internal power source, and
the location of the wellbore drone is determined by at least one of an external control system or the on-board control system, the location determination based on a flow speed of fluid along which the wellbore drone travels within the wellbore and a time passed after the wellbore drone is dispensed for being deployed into the wellbore.
