Downhole robotic shuttle for performing programed operations

A downhole robotic shuttle comprising:

• a plurality of modules configured to be coupled together in series wherein the series of modules is configured to be conveyed through a cased borehole penetrating a geologic formation;
• one or more of the modules in the plurality of modules comprising:
• a coupling mechanism configured to couple one module to an adjacent module, each module in the plurality comprising a first coupling mechanism at one end of the module and a second coupling mechanism at an opposing end of the module for coupling to the adjacent module;
• a movement mechanism configured to enable conveyance of the module comprising the movement mechanism through the cased borehole;
• a steering mechanism coupled to the movement mechanism and configured to steer the movement mechanism to achieve a selected orientation within the cased borehole;
• a motor configured to power the movement mechanism and/or the steering mechanism;
• an actuator configured to perform a selected action;
• a sensor configured to sense a selected parameter to provide sensed data;
• a memory configured to receive instructions for performing at least one of the selected action and another action;
• map information stored in the memory;
• a controller configured to control at least one of the motor, steering mechanism, actuator, or sensor in accordance with the instructions received from the memory and sensed data received from the sensor, the controller further configured to navigate the downhole robotic shuttle to a selected location based on the map information and the sensed data by controlling the steering mechanism.
