Cobot Assistance during assembly

Heavy physical or monotonous work is increasingly being performed in industry by collaborative robots. The Fraunhofer IEM supports especially small and medium-sized enterprises to use the so-called Cobots flexibly and cost-effectively. For this purpose, the research institute cooperates with RK Rose+Krieger as a full-range supplier of components and system solutions for automation technology. At the Hanover Fair, they present a solution for Cobot-supported assembly. An assistance robot mounted on two additional movement axes independently identifies components on an assembly workstation and supports the employees during the removal. It also measures and classifies the components and automatically carries out quality monitoring. Employees in the assembly department are thus provided with an intelligent assistant that takes unnecessary walking distances away from them and provides an additional eye on the work results. The assembly robots can be flexibly set up for new work orders without any programming knowledge.

SensPro - Sensor-based robot programming

The Rostock scientists present an innovative method for the automatic programming of welding robots for the production of steel volume structures. To emphasize the individual program generation, visitors can manipulate a freely movable model of a ship panel in such a way that a 3D laser scanner has to re-identify components and welding seams. Afterwards, welding paths are exemplarily scanned by the robot.

Computer-Aided-Safety (CAS)

Fraunhofer IFF presents Computer-Aided Safety (CAS), a new generation of tools for designing applications featuring Human-Robot Collaboration (HRC). As an add-on embedded into third-party simulation software for manufacturing, CAS simplifies the implementation of complex safety requirements for HRC. New design functions and interactive elements guide the application engineer through the corresponding safety limits for their application and streamline the entire process from layout to the final installation. Experience a new way to simplify robot safety.

Tactile Sensor

The tactile sensor system developed at the Fraunhofer IFF can be integrated in different grippers. The sensors’ spatial and force resolution makes it possible to detect objects’ presence as well as their position and even slippage in a gripper. Adaptive gripping strategies that build upon this permit adapting and optimizing processes responsively, gripping fragile objects sensitively, and classifying unidentified objects.

EPIC - Interactive demonstrator of the cooperation project

The Centre of Excellence in Production Informatics and Control is a long term cooperation between Fraunhofer IPK, IPT, IPA and Fraunhofer Austria and the Hungarian Partner EPIC Inno Labs. In our joint exhibit, we provide an interactive map demonstrating an overview of pilot CPPS use-cases that have been developed within this cooperation. In a virtual lab-tour, the user can experience innovative solutions regarding human robot collaboration.

Multimodal human-robot interaction at the visual inspection station

In the near future, robots will be positioned at visual inspection station. They will hold and move the heavy parts being inspected in an ergonomic position for the operator, while the operator checks the quality. This process, the 3D error documentation and the robot are operated by a projected AR interface using hand gestures and voice input. At the Fraunhofer HHI booth, among other things, interested visitors can control the  robot using their own gestures.

Mobile Interaktion³

Optimization of production and increased efficiency during ongoing operations - visitors of the fair will get to know this by a production scenario: The interaction between a person with a mobile robot and a moving workpiece (car door). The key feature: Algorithms for the recognition of human and workpiece allow autonomous and synchronous tracking. While doing so, the robot is placed on an automated guided vehicle system performing simultaneous real-time path planning.

Sensor integration and freedom of design for lightweight grippers

The live demonstration presents the adaption of lightweight grippers, attached to the Mini-SCARA-robot, to various objects. In doing so, the gripping force is measured by the integrated sensors and adjusted to the requirements of the workpiece in real-time. The additive manufacturing and the resulting freedom of design extend the range of functions, resulting in the precise production of custom-fit gripper solutions with adjusted features such as stiffness, strength, weight and gripper surface.
