According to one example of the invention, a drill rod handler includes a movable clamp. In one embodiment a computer machine is configured to receive a query as computer machine input, automatically determine at least one concept contained within the query and automatically normalize the at least one concept contained within the query, thus creating at least one normalized concept. The second step motor driver is configured for driving a second step motor and connected to the MCU. A test pin assembly is disposed at one end of the resource board and is connectable with a loadboard.
