The Real-Motion-Simulator (RMS) allows a very accurate replay of drive-files based on data-recording at test-roads with real vehicles. The simulation in the laboratory brings high flexibility and new options in testing. The simulator allows to adapt test-conditions and to simulate motion which is very difficult to test on real vehicles or only at high costs. The 6DOF-System brings all these functions at very interesting costs. The engineering-time is reduced and tests are already possible based on calculated data, before the final product exists. The 6DOF-Syste is also an interesting option when not all degress of freedom are used, but when other special test-benches can be simulated or replaced. OHE designs, builds and tests complete systems including hydraulic power-unit, controller and user-interface with a wide range of functions.

The Hexapod can also emphasize its special advantages with the testing of hull models in drag channels. Instead of producing artificially waves in the channel, the engineers turn the classical application around and move the ship's model as shown in the illustration. The measured reaction forces then allow to analysis the characteristics of the ship form. With the conventional method, where artificially waves are produced in the channel, the Hexamove system permits to bring the model rapidly into precise positions. Test sequences can be accelerated in such a way (or can be completely automated!).

This Hexapod-Positioning-System reaches new dimensions in accuracy and payload. The system can care up to 800 kg. The repeating-accuracy reaches 0.001 degrees in the angles and less then 0.01 mm in the translation. But the main advantage of the system is the large workspace compared to the size of the system. When fully retracted, the geometric altitude is less then 300 mm, but can move vertical about 500 mm! The complete system is build in aluminium and stainless-steel, so it has no magnetic parts. There are no electronic parts on the system which create magnetic field or which are reacting to magnic influences.

The picture shows a Hexapod-System which was build for very accurate positioning of sample workpieces in a Neutron-Beam. The accuracy of the system is better then +/- 0.01 mm. The robot can handle payloads up to a weight of 700 kg. The hydraulic drives allow a very compact design with a large workspace and the 6 degrees of freedom offer a great flexibility of the system.

The Hexapod-Concept offers great advantages for handling heavy payloads in 6 degrees of freedom. However, the Hexapod assembly-systems which Airbus required for mounting the landing gears of the new A380 aircraft were a real challenge. When retracted the system should have a heigth of only 800 mm but the vertical workspace must be almost 3000 mm. The workpiece-coordinate system of the different landing-gear units is fully integrated into the Hexamove-Kernel and the platform moves on virtual circles in space when rotating the workpiece around its main-bolts. An other challange was the large range of functions of the system starting from manual controlling with a panel up to almost automatic assembly functions. Innovative ideas make the Hexapod-System a very interesting tool and robot-system for handling heavy payloads.
