Abstract

A patient side cart for a teleoperated surgical system can include one or more wheels positioned to support the cart for wheeled motion on a ground surface, at least one manipulator portion for holding a surgical instrument, a steering interface having a grasping portion and comprising a sensor positioned to sense turning, fore, and aft forces exerted on the grasping portion to move the cart, wherein the sensor is in signal communication with a drive control system of the patient side cart, and an additional sensor operatively coupled to the drive control system. The additional sensor may be positioned between the steering interface and the wheels on a side of the cart at which the steering interface is positioned, wherein in response to a force exerted on the additional sensor during backward motion of the cart in response to an aft force exerted on the grasping portion, the sensor sends a signal to the drive control system to stop motion of the cart.
