Abstract
A technique facilitates drilling of wellbores or other types of bore holes in a variety of applications. A steerable system is designed with a main shaft coupled to a drill bit shaft by a universal joint to provide steering functionality. A sensor system is mounted on the steerable system and comprises at least one sensor positioned to measure desired parameters, such as weight on bit and/or torque on bit parameters during drilling.
