a post being substantially vertical and coupled to a base;
a robotic drive having a socket for receiving the post;
a first tapered key fixed to the post to engage the socket wherein the first tapered key comprises a first surface substantially parallel to the vertical axis of the post and a first sloped surface opposing the first surface in a first rotational direction about the vertical axis of the post, and
a second tapered key fixed to the post to engage the socket, wherein the second tapered key comprises a second surface substantially parallel to the vertical axis of the post and a second sloped surface opposing the second surface in a second rotational direction opposite the first rotational direction about the vertical axis of the post.
2. The robotic medical system of claim 1 , wherein the post is substantially cylindrical and the first and second tapered keys are positioned about 180 degrees apart along a circumference of the post.
3. The robotic medical system of claim 1 , wherein the socket includes tapered cavities shaped and positioned to receive the first tapered key and the second tapered key and cause physical engagement of the post and the robotic drive.
4. The robotic medical system of claim 1 , wherein the post includes at least one insertion interface to facilitate insertion of the post into the socket.
5. The robotic medical system of claim 4 , wherein the post is a cylinder and the insertion interface includes at least one cylindrical portion along a length of the post, the cylindrical portion being configured to engage an internal bushing of the socket.
6. The robotic medical system of claim 5 , wherein the at least one cylindrical portion includes multiple cylindrical portions spaced along the length of the post.
7. The robotic medical system of claim 6 , wherein the multiple cylindrical portions have progressively smaller diameters along the length of the post.
8. The robotic medical system of claim 4 , wherein the insertion interface includes a convex tip at a termination of the post.
9. The robotic medical system of claim 1 , wherein the first tapered key extends from a conical portion of the post to an outer periphery of the base of the post.
10. The robotic medical system of claim 1 , wherein the post has a cross-sectional shape selected from one of circular, oval, or polygonal.
11. The robotic medical system of claim 1 ,
wherein each of the first tapered key and the second tapered key extend from a conical portion of the post to an outer periphery of the base of the post.
12. A robotic medical system, comprising:
a positioning system coupled to a base, the positioning system including a substantially vertical post; and
a robotic drive having a socket for receiving the post,
wherein the post includes a first tapered key to engage the socket, the first tapered key positioned at a bottom end of the post and comprising a substantially vertical surface and a sloped surface opposing the substantially vertical surface in a first rotational direction about a vertical axis of the post, and
wherein the post includes a second tapered key to engage the socket, the second tapered key positioned at the bottom end of the post and comprising a second substantially vertical surface and a second sloped surface opposing the second substantially vertical surface in a second rotational direction opposite the first rotational direction about the vertical axis of the post.
13. The robotic medical system of claim 12 , wherein the socket includes a tapered cavity for receiving the first tapered key to cause physical engagement of the post and the socket.
14. The robotic medical system of claim 12 , wherein the post includes at least one insertion interface to facilitate insertion of the post into the socket.
15. The robotic medical system of claim 14 , wherein the insertion interface includes at least one cylindrical portion along a length of the post, the cylindrical portion being configured to engage an internal bushing provided in the socket.
16. The robotic medical system of claim 14 , wherein the insertion interface includes a convex tip at a termination of the post.
17. The robotic medical system of claim 12 , wherein the second substantially vertical surface is oriented to resist rotation of the robotic drive about at least the vertical axis.
18. The robotic medical system of claim 17 , wherein the socket includes a first tapered cavity for receiving the first tapered key to cause physical engagement of the post and the socket and a second tapered cavity for receiving the second tapered key to cause physical engagement of the post and the socket.
19. The robotic medical system of claim 12 , wherein the substantially vertical surface is oriented to resist rotation of the robotic drive in the first rotational direction about at least the vertical axis and the second substantially vertical surface is oriented to resist rotation of the robotic drive in the second rotational direction about at least the vertical axis.
