Abstract
An object manipulator robot device includes a pick-up member made from a thermally conductive material and having at least one surface of contact with the object to be picked up, a system for cooling the pick-up member to freeze the interface between the member and the object, thereby fastening them together, including a local system for cooling the pick-up member directly and a peripheral system for cooling the local system, a system for heating the member to liquefy the interface, thereby releasing the object, and a control system for the cooling and heating systems. The local cooling system includes a pair of local cooling elements mounted on respective opposite sides of the pick-up member and the peripheral cooling system includes a pair of peripheral cooling elements connected to the local cooling elements by arms made from a material of high thermal conductivity, such as copper.
