Abstract: The invention pertains to a method of calibrating robots without the use of external measurement equipment. The invention furthermore pertains to a method of copying working programs between un-calibrated robots. Both methods utilize the properties of a closed chain and the relative position of the links in the chain in order to update the kinematic models of the robots.
