Force sense display device and force sense display method
A medical robot system includes a memory and central processing unit that performs operations including receiving measurement signals of a gripping force, which is a force to grip an object by a surgical tool, and a dissecting force, which is a force to dissect the object by the surgical tool, generating image information for displaying information on the gripping force as a grip display mode and information on the dissecting force as a dissection display mode different from the grip display mode, based on the measurement signals, and outputting the image information to a display portion of a display that is configured to display the image information.
