The ornamental design for robotic patient drape, as shown and described.
FIG. 1 is a side perspective view of a robotic patient drape showing my new design;
FIG. 2 is a top plan view of the robotic patient drape shown in FIG. 1; and,
FIG. 3 is a bottom plan view of the robotic patient drape shown in FIG. 1.
In the drawings, the broken lines representing the table legs in FIG. 1 illustrate environment and form no part of the claimed design. All other broken lines represent features of the robotic patient drape that form no part of the claimed design.
