ABSTRACT:
A super-elliptical adaptor ring for adapting a substantially rectangular refuse container to be readily handled by a robotic manipulator of substantially rounded objects. The outer surface of the adaptor ring has a super-elliptical horizontal cross-section. The super-ellipse defining the outer surface has an exponent between about 4.0 and about 1.5, and preferably between about 3.5 and 1.7. Optimally the super-ellipse has an exponent of about 3.0 and a ratio of length to width of about 35:32. The inner mating surfaces of the adaptor ring define a substantially rectangular horizontal cross-section conforming to the exterior shape of the container. The adaptor is removably mounted on the container by sliding the adaptor upwardly around the container until the adaptor is frictionally arrested by the exterior walls of the container. The adaptor is retained on the container by the lift bar of the container in proximal contact with the bottom of the adaptor, and by two locking arms extending upwardly above the adaptor and engaging the handle near the upper edge of the container's rear wall. A wedge-shaped element extends above the adaptor ring into a pocket formed behind a lip at the upper edge of the container's front wall.
