## Abstract

Devices, systems, and methods for a robot-assisted surgery. Navigable instrumentation, which are capable of being navigated by a surgeon using the surgical robot system, and navigation software allow for the navigated placement of interbody fusion devices or other surgical devices.

## Claims

### Claim 1

A retro-reflective disk assembly for a robotic system, the retro-reflective disk assembly comprising:
an upper portion comprising coupling features at a distal end;
a lower portion configured to couple to the upper portion via the coupling features; and
a reflective film configured to be adhered to an upper flat surface of the lower portion, wherein the upper portion comprises a through-hole extending from a proximal end to the distal end such that the reflective film is visible when the retro-reflective disk assembly is fully assembled.

### Claim 2 (depends on 1)

The retro-reflective disk assembly of claim 1, wherein the upper portion comprises a chamfered upper surface at the proximal end.

### Claim 3 (depends on 1)

The retro-reflective disk assembly of claim 1, wherein the upper portion comprises a plurality of slots allowing the distal end of the upper portion to be flexible.

### Claim 4 (depends on 1)

The retro-reflective disk assembly of claim 1, wherein the upper portion comprises a plurality of openings, wherein each opening of the plurality of openings is configured to receive an extension located on the lower portion.

### Claim 5 (depends on 1)

The retro-reflective disk assembly of claim 1, wherein the lower portion comprises a plurality of extension, and each extension of the plurality of extensions comprises a flexible tab.

### Claim 6 (depends on 1)

The retro-reflective disk assembly of claim 1, wherein the lower portion comprises a cylindrical lower end that is hollow and configured to receive a post of an array.

### Claim 7 (depends on 1)

The retro-reflective disk assembly of claim 1, wherein the reflective film is configured to be visualized by a camera system.

### Claim 8

A robotic system comprising: a robotic arm electronically coupled to a computer and moveable based on commands processed by the computer; an end-effector electronically coupled to the robotic arm; a dynamic reference base; a plurality of tracking markers, each tracking marker configured to be received by a post of the dynamic reference base, wherein each of the tracking markers comprises: an upper portion comprising coupling features at a distal end; a lower portion configured to couple to the upper portion via the coupling features; and a reflective film configured to be adhered to an upper flat surface of the lower portion, wherein the upper portion comprises a through-hole extending from a proximal end to the distal end such that the reflective film is visible when the retro-reflective disk assembly is fully assembled.
