Cable-driven parallel robots - Motion simulation in a new dimension

10.09.2015

Under the lead of the Tübingen-based Max Planck Institute for Biological Cybernetics (MPI), Fraunhofer IPA has co-developed a new cable-driven parallel robot that is the first one capable of transporting humans while at the same time setting new standards in terms of workspace, acceleration and payload for a motion simulator. The scientists have thus succeeded in decisively advancing a technology previously used for automation solutions in the field of intralogistics. On 16 September 2015, MPI will unveil the motion simulator to the public at the Driving Simulation Conference & Exhibition (DSC2015) in Tübingen.

To date, cable robots have been used in production environments, where they meet high requirements. The systems surpass conventional industrial robots in size and pay- load by between one and two orders of magnitude. The end effector can be freely moved with high accuracy by up to eight cables and winches. Based on this technology and in a world first, the idea of a cable-driven motion simulator has now been realized under the lead of Professor Heinrich Bülthoff from MPI for Biological Cybernetics.

Technical innovations

In the cable-driven simulator, the motion of the simulator cabin is controlled by eight unsupported steel cables attached to winches. In contrast to conventional motion simulators, the use of cables makes it possible to reduce the moving mass and to scale the workspace to any required size. A total drive power of 348 kW allows the cabin to accelerate at 1.5 times gravitational acceleration along freely programmable paths inside a 5 x 8 x 5 m³ workspace.

In addition, the cables can be reattached in under an hour to enable the simulator to be adapted to different cabins and thus used for a range of scenarios. During the two-year collaboration between both Institutes, Philipp Miermeister, a member of Fraunhofer IPA’s Cable Robotics working group headed by Junior Professor Andreas Pott, has contributed much know-how to driving forward the design and realization of the simulator.

The scientists have not only implemented the control algorithms, but also developed a lightweight yet rugged carbon fibre cabin capable of withstanding the high dynamic loads during operation. Made entirely from carbon fibre tubes, the cabin frame maximizes the usable cabin volume with a diameter of 260 cm for projection surfaces and cockpit instrumentation. This allows it to be used for highquality video projections and realistic operator interfaces.

At the same time, the light 80 kg frame is capable of accelerating at high speed while also withstanding high forces, because, in operation, the cables pull on the outer structure with up to 1.5 tonnes. Its large workspace and dynamic capabilities make the simulator suitable for a wide spectrum of VR (virtual reality) applications, including driving/flight simulation as well as investigation of basic perception processes in humans.

“This simulator offers us entirely new possibilities for studying motion perception with possible applications in neurological research into balance disorders,” says Professor Bülthoff, who is a long-time perception researcher.

Successful collaboration

There is a history of collaboration between the Fraunhofer and Max Planck Institutes.
“With the cable-driven simulator, the scientists from both Institutes have once again demonstrated how the combination of basic research and industry-oriented technology development can lead to innovative products,” underlines Professor Thomas Bauernhansl, Institute Director at Fraunhofer IPA.

Maiden journey of the cable-driven simulator

During a welcoming reception at the Driving Simulation Conference & Exhibition (DSC2015), the scientists will unveil the cable robot to a wider audience. One of Europe’s leading conferences in the field of driving simulation, DSC is being held in Germany for the first time. Taking part alongside MPI are the Mercedes-Benz Sindelfingen plant of Daimler AG as well as the Research Institute of Automotive Engineering and Vehicle Engines (FKFS) from the University of Stuttgart. Coupled with an exhibition, the conference attracts experts from research and industry. Journalists are welcome to attend the reception at 7 p.m. on 16 September; those wishing to attend are requested to register: presse-kyb@tuebingen.mpg.de
