The Digital TwinComputer-aided,realistic Simulation with theSCHUNK SVH 5-Finger Gripping Handin Real Time

The new Trend:Digitalization in Automation

Ever shorter go-to-market cycles constitute a massive challenge to manufacturing companies. In this context the digitalization in production is one of the key topics. The used three-dimensional models ensure an excellent presentation of machines and components during the design and development phases. However, programming of the control unit and commissioning is not done before the set-up of the machine. This is where the concept of the Digital Twin comes into play.

Digital Twin – What does this mean?

A Digital Twin is the digital form of a real object. Based on a CAD three-dimensional model, it has all the product properties, functions, and process parameters – from the material, the sensor system, up to the motion and dynamics available. As an intelligent three-dimensional model, the Digital Twin allows a realistic simulation in a computer-aided simulation environment. All the aspects of operation and the processes can be executed in real time. This allows programming start of the process, its optimiza-tion and the testing of extreme situations before the avail-ability of individual components and modules. In short: Already during the planing phase a digital commissioning is possible.

Digital Twin – What are the advantages?

The robot’s and plant’s control program can be developed in parallel to the plant design

Plant and process design can be optimized during the planning phase

Easy commissioning with enormous time saving

Trouble-free operation from the start

Digitally integrated now!The SCHUNK SVH 5-Finger Gripping Hand

As a competence leader for clamping technology and gripping systems, SCHUNK paves the way to digital technology for o� ering their top products in a digital form for the whole simultaneous engineering process to their customers in future. The aim is a long-term digitalization of SCHUNK products as a part of Industry 4.0. The Digital Twin of the SCHUNK SVH 5-finger gripping hand has been developed together with the so� ware developer TruPhysics as a competent partner. Due to their many degrees of freedom and the control, programming of the SCHUNK SVH is very demanding and time-consuming.

The methods of a conventional o� ine and online programming are bundled and integrated with the

supplementary so� ware modules/packages of TruPhysics to a complete solution, which allows virtual online programming. The data of the SCHUNK SVH are converted and are played into the native RC control unit of the robot. The Digital Twin of the SCHUNK SVH is connected with the Digital Twin of the real robot via IP port for simulation. Depending on the extent of the describing behav-ioral characteristics, the virtual robot then reports realistic values from the simulation environment back to the control unit in real time.

The unique contact simulation module from TruPhysics recognizes possible interfering contours. Collisions can be considered and excluded. Dam-ages to the SCHUNK 5-finger gripping hand, and the resulting high repair costs can be avoided.

Customer benefits:

Easy programming

Due to the virtual support of TruPhysics, programming is now much easier than it was in the past.

Enormous time-saving when commissioning

The virtual programming of the SCHUNK SVH is very time-consuming. Instead of programming during commissioning, programming could be already done in the planning phase without hardware.

Force application to the workpieces

Since the SCHUNK SVH is o� en used in contact with humans the in� uences of the gripping forces can be simulated, taking the possible danger to humans out of the equation.

Optimization during operation

The SCHUNK SVH is very � exible in gripping of various workpieces. Due to the simulation with the Digital Twin, the best type of gripping can be determined.
