Pushing Manipulation for Multiple Objects

This paper discusses the manipulation of multiple objects by pushing. When multiple objects are placed on the flat floor and manipulated simultaneously by pushing, relative motion between two objects such as sliding and rotation may occur. The set of the pusher motion manipulating objects stably is obtained as an intersection of multiple sets of pusher motion where each set prevents the relative motion at one of the contact areas. Experimental results are also included to show the effectiveness of our Idea
