A drilling rig system including a man-machine workstation interface located in proximity to the drilling rig for providing to a single operator at substantially one location simultaneous operational access to drilling rig processes. The workstation includes an adjustable base and an operator alcove

A drilling rig system including a man-machine workstation interface located in proximity to the drilling rig for providing to a single operator at substantially one location simultaneous operational access to drilling rig processes. The workstation includes an adjustable base and an operator alcove formed on the base in which an operator is positioned allowing for a substantially unobstructed view of the drilling rig. Adjustable forearm support panels are formed on opposing sides of the operator alcove for supporting the forearms of the operator while positioned in the alcove. At least one display unit is adjustably connected to the base and has a touch access screen adapted to allow the operator to monitor and control drilling rig processes. A plurality of discrete hand controls are used for controlling predetermined drilling rig processes wherein at least one of the discrete hand controls is located on the forearm support panels. Preferably, an operator chair is positioned in the alcove and is slideably connected to the base permitting seating and standing operation of the workstation. Data from multiple associated drilling equipment is integrated with data from a current drilling rig process to provide data to the operator on a process oriented basis displayed on said display units.

The apparatus of claim 7 wherein the plurality of linkages each further comprises at least one wheel rotatably attached to at least one of the second end of the first arm and the second end of the second arm, wherein each wheel is adjacent to one of the bi-directional gripping cams. 9. The apparatus of claim 7 wherein the plurality of linkages each further comprises a biasing device adjacent to the bi-directional gripping cam, the biasing device adapted to force the cam laterally away from the grip body. 10. The apparatus of claim 7 wherein the extension and locking mechanism comprises an actuator rod having a first end and a second end, and a piston wherein the first end of the actuator rod is attached to the hub, and the second end of the actuator rod is attached to the piston, wherein the piston is adapted to move the actuator rod. 11. The apparatus of claim 10 further comprising a spring having a first end and a second end, wherein the first end of the spring is operatively coupled to the grip body, and the second end of the spring is operatively coupled to the piston, wherein the spring is adapted to exert a force on the piston, in a direction selected to force the plurality of linkages radially inward towards the grip body. 12. The apparatus of claim 11 further comprising a cylinder chamber, wherein the cylinder chamber encloses the piston and the spring. 13. The apparatus of claim 7 wherein the extension and locking device is adapted to automatically bias the linkages to a closed position upon a loss of electrical power. 14. The apparatus of claim 7 wherein the extension and locking device comprises a ball screw and a plurality of ball nuts operatively coupled to a motor. 15. The apparatus of claim 14 wherein the extension and locking device comprises a brake operatively coupled to the ball screw. 16. The apparatus of claim 7 wherein the extension and locking device comprises a source of high pressure fluid and at least one piston. 17. The apparatus of claim 16 wherein the extension and locking device is adapted to lock by selectively closing hydraulic communication to cylinder chambers enclosing each piston. 18. A method for conveying a tool body through a conduit, comprising: (a) moving a bi-directional gripping cam into contact with an inner wall of a conduit; (b) laterally locking a position of the cam; and (c) moving the tool body axially with respect to the cam in a first direction. 19. The method of claim 18 further comprising: (d) releasing the lateral position of the cam; (e) moving the cam axially along the inner wall of the conduit so as to reverse an orientation of the cam; and (f) relocking the lateral position of the cam and moving the tool body in a second direction. 20. The method of claim 18 further comprising: (d) locking the axial position of the tool body; (e) releasing the lateral position of the cam; and (f) moving the cam axially with respect to the tool body in the first direction. 21. The method of claim 20 wherein said (a) through (f) are repeated until the tool body has reached a predetermined location. 22.
