3. The medical system of claim 2 , wherein the object detection device is chosen from at least one of a contact switch, a resistive touch sensor, an accelerometer, or a force or torque sensor.
4. The medical system of claim 1 , wherein the control system is configured to automatically control movement of the mobile cart by preventing translating movement of the mobile cart along the trajectory on a condition of a height of the mobile cart being equal to or within a predetermined range of the threshold height.
5. The medical system of claim 1 , wherein the control system is configured to receive information from the object detection device and, in response to detection of an object in the trajectory of movement of the mobile cart, determine if the detected object is an obstacle impeding movement of the mobile cart along the trajectory.
6. The medical system of claim 1 , wherein the object detection device is configured to detect an object using at least one of light, ultrasound, infrared, and imaging detection mechanisms.
7. The medical system of claim 1 , wherein the object detection device comprises at least one of a laser, a light detection and ranging (lidar) device, an ultrasonic range finding device, an optical infrared ranging device, or an imaging device.
8. The medical system of claim 1 , wherein the object detection device comprises a camera, and wherein the control system is configured to receive an image from the camera and to detect the object by analyzing the image.
9. The medical system of claim 1 , wherein a height of the mobile cart is adjustable, and the control system is further configured to:
automatically prevent adjusting the height of the mobile cart from exceeding a height within a predetermined range of or equal to the threshold height.
10. A mobile cart for a teleoperated surgical system, the mobile cart comprising:
a column extending from a base, the column having a first end connected to the base and a second end opposite the first end;
a surgical instrument manipulator arm coupled proximate the second end of the column; and
an object detection device mounted on the mobile cart at a height above a location where the surgical instrument manipulator arm is coupled to the second end of the column, the height being measured in a direction the column extends from the base.
11. The mobile cart of claim 10 , wherein the object detection device is configured to detect physical contact with an object.
12. The mobile cart of claim 10 , wherein the object detection device is chosen from at least one of a contact switch, a resistive touch sensor, an accelerometer, or a force or torque sensor.
13. The mobile cart of claim 10 , wherein the object detection device is chosen from at least one of a laser, a light detection and ranging (lidar) device, an ultrasonic range finder device, an optical infrared ranging device, or an imaging device.
14. The mobile cart of claim 10 , wherein the object detection device is configured to detect an object using at least one of light, ultrasound, infrared, and imaging detection mechanisms.
15. A method of operating a mobile cart for a teleoperated surgical system, the method comprising:
setting a threshold height based on a selection from one of a plurality of predetermined heights stored in a memory operably coupled to the mobile cart, wherein the mobile cart comprises a manipulator arm configured to removably mount one or more medical instruments; and
automatically controlling a configuration or movement of the mobile cart based on the threshold height.
16. The method of claim 15 , wherein the plurality of predetermined heights stored in the memory correspond to a plurality of different locations in which the mobile cart is anticipated to be positioned.
17. The method of claim 15 , further comprising:
using an object detection device mounted on the mobile cart to detect one or more objects at each of a plurality of locations; and
storing the plurality of predetermined heights corresponding to respective heights of the one or more objects detected at each of the plurality of locations.
18. The method of claim 15 , wherein automatically controlling a configuration of the mobile cart comprises preventing adjusting a height of the mobile cart to a height equal to or within a predetermined range of the threshold height.
19. The method of claim 15 , wherein automatically controlling movement of the mobile cart based on the threshold height comprises preventing a translating movement of the mobile cart along a ground surface during a condition of the height of the mobile cart being equal to or within a predetermined range of the threshold height.
20. The method of claim 15 , further comprising:
detecting an object in a trajectory of movement of the mobile cart along a ground surface using an object detection device mounted on the mobile cart; and
resetting the threshold height to a new threshold height in response to detecting the object is at a lower height from the ground surface than the threshold height.
