Abstract: A method of generating a robot path is provided. The method includes identifying a drawing pose set for a manipulator included in a robot in order to draw a two-dimensional (2D) image on a three-dimensional (3D) target surface, setting a profile curve by projecting surface points of the 3D target surface onto an xy-plane, determining coverage circles of the manipulator that are capable of covering all surface points of the profile curve, deriving bounding circles for a mobile platform of the robot mounting the manipulator, corresponding to each of the determined coverage circles, and generating a translation path of the robot for drawing the 2D image on the 3D target surface based on the derived bounding circles.

Abstract: A method and a system for providing a roughness haptic sense of a virtual object by using space-time encoding are provided. The method for providing a roughness haptic sense of a virtual object may comprise the steps of: displaying virtual objects to a user; tracking the position of the user's hand; predicting a virtual object, which is most likely to collide with the hand, among the virtual objects; and when the hand touches a haptic sense providing device, controlling the haptic sense providing device on the basis of the surface roughness of the predicted virtual object to feed back a roughness haptic sense to the user.
