Abstract: A drive assembly of a surgical robotic system is disclosed herein. In some embodiments, the drive assembly includes a first drive unit having a first drive unit face, a second drive unit having a second drive unit face, and a third drive unit having a third drive unit face. Each drive unit may include a plurality of motors configured to rotate a corresponding one of a plurality of drive elements about rotational axes perpendicular to the respective the respective drive unit face. the first drive unit, the second drive unit, and the third drive unit configured to be positioned about the drive assembly common axis with respect to a vertical plane passing through the drive assembly common axis such that an orientation and position of the first drive unit face mirrors those of second drive unit face, and the third drive unit face is bisected by the vertical plane.

Abstract: Systems and methods employing cartridges for securing one or more tool elements of a surgical tool and releasing the tool elements when engaged by a distal end of a robotic arm are provided. A cartridge includes a cartridge body, a holder disposed in a cartridge body and configured to engage tool elements, a spring connecting the holder to the cartridge body, and a pair of biasing elements each attached to the cartridge body at a first end and having a retention mechanism at a second end, the retention mechanism configured to engage corresponding receiving mechanisms of tool elements. Also provided is a cartridge with an RFID tag and/or RFID tag and RFID blocking flag systems to identify proximity of a distal end of a robotic arm.

Abstract: A surgical robotic system and a method of controlling a location of one or more robotic arms in a constrained space are disclosed herein. In some embodiments, the robotic system includes a robotic unit having robotic arms. The system further includes a camera assembly to generate a view an anatomical structure of a patient. The system further includes a controller configured to or programmed to define a constriction area defining safe movement of the robotic arms. The method includes defining safe movement of the robotic arms with respect to the constriction area.
