A method for wrapping a substantially annular object with wrapping material dispensed as a sheet from a roll, using a rotating device and at least one robotic arm under control of a processor, comprising: rotating said annular object about its rotational axis; grasping said roll of wrapping material with at least one gripper having two opposing surfaces, mounted on said at least one robotic arm; and carrying said roll of wrapping material, via said robotic arm, around at least one surface of said annular object as it rotates, including at least the inner surface of its cylindrical center hole; said grasping including securely holding said wrapping material between said opposing surfaces so as to enable said at least one robotic arm to carry the material around said at least one surface of said annular object. 6. A method for wrapping an annular object as in claim 5, wherein said at least one robotic arm includes a first and second robotic arm, and said at least one gripper includes a first and second pair of grippers, further comprising: grasping said material with said first pair of grippers mounted on said first arm; carrying said material around said object to said second arm; exchanging said material with said second pair of grippers mounted on said second arm; and carrying said material around said object back to said first arm. 7. A method for wrapping an annular object as in claim 6 wherein each robotic arm includes at least one slide, said carrying step further comprising: raising and lowering each of said robotic arms, via said at least one slide, from the cylindrical center hole to the outside surface of said annular object; such that said at least one surface of said annular object includes its outer surface and the inner surface of its cylindrical center hole. 8. A method for wrapping an annular object as in claim 5, wherein said at least one robotic arm includes a pair of robotic arms, and said at least one gripper includes two pairs of grippers, further comprising: grasping said material with a first of said pairs of grippers mounted on a first of said arms; releasing said material from the second of said pairs of grippers mounted on the second of said arms; carrying said material around said object via said first arm to the second of said arms; grasping said material with said second pair of grippers mounted on said second arm; releasing said material from said first pair of grippers mounted on the first of said arms; carrying said material around said object back to said first arm, such that said at least one surface of said annular object includes the inner surface of its cylindrical center hole. 9. A method for wrapping an annular object as in claim 5, further comprising: generating signals indicative of the size of said annular object via at least one sensing device; and adapting said robotic arm via a processor, in response to signals received from said sensing device. 10. A method for wrapping an annular object as in claim 9, further comprising: sensing the height of said object and its cylindrical rotational axis, and the distance between said object and said robotic arm; and adapting the movement of said robotic arm to wrap said object in accordance with the sensed height and rotational axis of said object, and the sensed distance to said object. 11. A method for wrapping an annular object as in claim 5, wherein: adapting said rotating device, via a processor, in response to signals receiv
