Cambio --- a miniaturized tool changer for desktop factory application. For desktop factories highly miniaturized assembly robots in conjunction with handling and feeding systems are needed. Thus the size adapted robot Parvus was built and tested at the IWF. Meanwhile the robot can be equipped with different grippers. For enabling a flexible use of these grippers a tool changer has been designed to extend the functionality of the Parvus system. This tool changer, named Cambio, is a size adapted system that will allow a complete tool changing within a running assembly process in a future desktop factory.
