1. A robotic catheter navigation system having a first shaft, a second shaft, a third shaft, and a fourth shaft, the robotic catheter navigation system comprising:
a catheter handle comprising 1) a first set of gears coupled to the first shaft and 2) a second set of gears coupled to the third shaft;
a first motor for rotating the second shaft;
a second motor for rotating the fourth shaft;
an outer torque transfer disk directly coupled to the first shaft and the second shaft for transferring the rotation of the second shaft to the first shaft to thereby rotate the first set of gears for steering a catheter; and
an inner torque transfer disk configured to nest within the outer torque transfer disk, the inner torque transfer disk coupled to the third shaft and the fourth shaft for transferring the rotation of the fourth shaft to the third shaft to thereby rotate the second set of gears for steering the catheter.
