Devices, systems and methods for detecting a position of an object with a robot surgical system having an articulable, separable camera stand. The surgical robot system may include a robot having a robot base with a robot arm and an end-effector coupled to the robot arm. The end-effector, surgical instruments, the patient, other objects, or any combination thereof, may be tracked via active and/or passive tracking markers. A camera, such as an infrared camera, a bifocal camera or a stereophotogrammetric infrared camera, is mounted on a separable camera stand and is able to detect the tracking markers when in use. Using the camera, the robot determines a position of the object from the tracking markers, which may be a three-dimensional position of the object or the markers. When convenient, the camera base may be assembled into the robot base, e.g., by sliding the camera base into the robot.
