A supporting and orienting apparatus that is angularly agile and can balance the weight of tools, and permits quick tool replacement is disclosed. An inner gimbal portion holds the tool at its center of balance and is rotationally disposed within an outer gimbal portion. The gimbal portion combination is rotationally attached to an articulated arm. The tool with one or both gimbal portions attached can be removed and replaced with another tool, also having gimbal portions attached such that the tool is automatically balanced when inserted into the support apparatus.

1. A support and orienting system comprising: an inner gimbal portion having a tool grasping device configured to grasp a tool and having a first rotation component;an outer gimbal portion configured to be disposed concentrically with and outside of the inner gimbal portion and having a second rotation component complementary to the first rotation component and interfaced therewith such that the inner gimbal portion rotates within the outer gimbal about a first axis;the outer gimbal connecter to a yoke structure, the yoke structure having a yoke rotatable with the outer gimbal about a second axis;the yoke connected to a yoke support and rotatable there with about a third axis wherein the first axis, second axis and third axis are mutually perpendicular;pivot mounting ears disposed on the outer gimbal portion to offset the pivotal attachment point of the outer gimbal on the yoke from the plane of the outer gimbal portion; andthe pivot ears are adjustable to vary the offset amount. 2. The support and orienting apparatus of claim 1 wherein the inner gimbal portion is releasably secured to the outer gimbal portion to allow tool removal with the tool and inner gimbal portion attached to one another. 3. The support and orienting apparatus of claim 1 wherein the outer gimbal portion is releasably secured to the yoke structure to allow tool removal with the tool, inner gimbal portion and outer gimbal portion attached to each other. 4. The support and orienting apparatus of claim 1 wherein the inner gimbal portion comprises: a tool holding ring comprised of a plurality of arcuate segments such that the ring can be assembled around the tool. 5. The support and orienting apparatus of claim 4 wherein the tool grasping mechanism comprises a plurality of set screws. 6. The support and orienting apparatus of claim 4 wherein the tool grasping mechanism comprises a plurality clamping screws. 7. The support and orienting apparatus of claim 1 wherein; one of the first or second rotation components is a race in one of the outer surface of the inner gimbal portion or the inner surface of the outer gimbal portion; andthe other of the first or second rotation component is a plurality of wheels rotatably mounted in the other of the inner gimbal portion or outer gimbal portion, the wheels disposed partially in the race;wherein when the inner gimbal portion is disposed in the outer gimbal portion the plurality of wheels is disposed edgewise within the race, thus allowing the inner gimbal portion to rotate within the outer gimbal portion; andwherein wheel axes are substantially parallel to the axis of the tool portion about which the tool rotates with respect to the outer gimbal portion. 8. The support and orienting apparatus of claim 1 wherein: the first rotation component is a race in the outer surface of the inner gimbal portion;the second rotation component is a race in the inner surface of the outer gimbal portion;both races are in substantially the same plane, and the apparatus further comprises:at least one ball bearing notch disposed in and extending to the upper surface of the inner gimbal portion wherein the upper surface is referenced to the inner gimbal portion when disposed horizontally;at least one ball bearing notch disposed in and extending to the upper surface of the Outer gimbal portion wherein the upper surface is teferenced to the puter gimbal portion when disposed horizontally;wherein when the inner gimbal portion is disposed within the outer gimbal portion, and the notches in each are aligned with one another, they form a ball bearing insertion opening; anda plurality of ball bearings disposed within the races such that each ball bearing is partially disposed in both races, thus allowing the inner gimbal portion to rotate within the outer gimbal portion. 9. The support and orienting apparatus of claim 1 wherein the inner gimbal portion comprises a plurality of arcuate segments. 10. The support and orienting apparatus of claim 9 wherein the outer gimbal portion is hinged at the interface of at least two arcuate segments allowing one hinged segment to swing open from the other hinged segment thereby facilitating removal of the inner gimbal portion. 11. The support and orienting apparatus of claim 10 further comprising a quick-release clamp to secure the arcuate segments together at a point opposite the hinged interface. 12. The support and orienting apparatus of claim 10 further comprising a gate hinge extender. 13. The support and orienting apparatus of claim 1 further comprising: an adjustable balancing component to adjust the center of mass of the tool.
