Robot vision technology packages - LHRobotics.Vision

Liebherr is making its expertise in the field of industrial robot vision applications available to a wide user group with the LHRobotics.Vision technology packages.

An eye for detail

The technology package

The technology package includes LHRobotics.Vision Software, which makes both precise object identification and selection and collision-free part withdrawal possible. Optionally, the software can also manage robot path planning up to the deposit position. An additional project-based vision system is required for this application.

Software

Basic licence

The inexpensive basic licence includes workpiece recording as well as collision-free removal. This version is ideal for applications in which the deposit position and corresponding path planning should not be taken over by the LHRobotics.Vision Software. The collision check is limited to the gripper model and, in this version, the robot’s interfering contour is not taken into account. That makes this variant particularly suitable for flat cases or large grippers that plunge deep into the bin.

With the basic licence, LHRobotics.Vision cab be operated in a limited version. The following functions have been left out of the basic licence:

  • Creation of deposit positions and therefore also path planning for deposits.
  • Addition of obstacles
  • Addition of a robot model

Pro licence

The pro licence offers the complete functional range of the LHRobotics.Vision Software. In addition to the basic licence features, the following data functions are available in this version:

  • Creation of a robot model for collision checks
  • Creation of deposit positions
  • Path planning up to the deposit position
  • Input of the complete cell environment for collision checks during path planning

This version is particularly suited to applications in which the deposit position of the workpiece once it has been removed is important for the process sequence

Smart bin picking software

Designing a complex application without absolutely no knowledge of programming? LHRobotics.Vision makes it possible: The intuitive graphic control panel makes it easy to enter all the necessary information quickly, starting with:

  • Creation of workpieces
  • Configuration of transport containers

It is possible to create models directly in the software using simple geometry or to import any available CAD data.

Artificial intelligence lights the way

From Version 3.4 on, the optimisation of detection parameters is aided by means of AI.

The user creates a point cloud and classifies it by manually positioning actual workpieces within the point cloud. This points out to the software the areas where the workpieces should be looked for. The software then carries out several automatic scans and independently adjusts the detection parameters. After several iterations, the software determines the optimal settings for recognising workpieces.

Optimisation of workpiece detection with AI-supported point cloud segmentation

In order to more quickly and precisely detect workpieces, Liebherr also uses AI support for segmentation of the point clouds. With the help of AI, a point cloud is divided into partial segments before workpieces are matched to it. This means that the LHRobotics.Vision Software only looks for the workpieces in the defined areas. Segments that are not assigned to the workpieces, such as walls and the floor of the bin, are removed from the point cloud and ignored.

The right camera for every application

LHRobotics.Vision is equipped with an open sensor interface and can integrate vision systems from Ensenso, Zivid, Keyence, Photoneo and Sensopart, to name just a few. Additional sensors from other manufacturers can also be used with the software.

The range of suitable sensors is determined by several factors. The important thing is the position of the sensor: on-arm or stationary.
