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.
