AI Technical Summary

Technical Problem

Existing methods for determining the three-dimensional orientation of objects relative to a robot are inefficient, requiring extensive setup and prior knowledge of object sizes and gripping postures as the number of components increases.

Method used

A method using a target marker with a predetermined number of encoding modules in a defined module pattern, which encodes object and gripping parameters, allowing for the determination of the three-dimensional orientation and gripping posture of an object without prior knowledge or extensive setup.

Benefits of technology

Enables efficient and accurate recognition and grasping of objects by providing all necessary information encoded in the target marker, reducing setup effort and allowing for flexible gripping processes.

Abstract

The invention provides a target marker (1) for determining a three-dimensional pose of an object (4), the target marker (1) having a predefined number of coding modules (2). According to the invention, the coding modules (2) of the target marker (1) are present in a defined modular pattern (10) that encodes a string containing specific information defining object parameters of the object (4) selected from the group comprising at least the size of the target marker (1) and / or gripping parameters for gripping a given object (4) from the group comprising at least the gripper gripping pose, the gripper geometry and the gripper force.
