Abstract

A method of calibrating a manipulator of an industrial robot, the method including providing a primary manipulator having one or more primary joints and a primary mounting interface; providing a secondary manipulator having one or more secondary joints and a secondary mounting interface, where the primary mounting interface is substantially rigidly connected to the secondary mounting interface; providing a load sensor between the primary mounting interface and the secondary mounting interface, the load sensor being configured to provide load data indicative of loads between the primary mounting interface and the secondary mounting interface; controlling the primary manipulator to adopt at least one calibration state; for each calibration state, recording a primary joint position of at least one primary joint; and calibrating the secondary manipulator based on the at least one recorded primary joint position; wherein the primary manipulator is controlled to adopt the at least one calibration state based on the load data; and/or wherein the calibration of the secondary manipulator is additionally made based on the load data.
