Interactive Motion Simulators
Interactive Motion Simulators
(Flight, Sailing, Driving Simulator)
Making it possible to experience virtual worlds interactively, and not merely visually, places extreme demands on 3-D software and requires the mechanical implementation of movement. SimBOT simulators offer a unique possibility for this: hybrid interaction with human operation.
This allows electronic control units and the operator’s handling to be included realistically in the calculation of movements. In this manner, the motion simulators can be used in a versatile manner, and different types of movement (e.g., flight and ground-based travel) can be carried out with a single system.
Thus SimBOT Simulators, with their flexible options for use, meet the rapidly increasing requirements of airplane and helicopter crews, and they make it possible to carry out simulations under conditions that closely approximate reality. The flexibility of the system has already been demonstrated in the areas of medical research, utility vehicle development and flight simulation.
In the case of simulating utility vehicles in developmental phases, the priority goals include energy efficiency, productivity, operational stability and reliability. To this end, all external influences on the vehicle must be taken into account and modeled as closely as possible. This not only includes the loads applied, but also explicitly the effects of the Operator or driver of the machine.
To master this DGWorld and its partners have developed the motion platform and real-time software for an interactive driving simulator ,which is used for the virtual simulation of utility vehicle product models. The new system is currently the only simulator worldwide that offers interactive human operation on the basis of six-axis robot kinematics, with a 1,000 kg working load and great freedom of motion.
The first step toward interactive performance of a flight on a robotic arm was taken in 2010 by KUKA & Partners at the Center for Robotics and Mechatronics of the German Aerospace Center (DLR), where a robot-based motion simulator was mounted on a 10-meter linear axis. Thanks to the modular design of the simulator pod, instrument modules could be easily exchanged, and different aircraft or helicopter simulations could be carried out. The results of this research have already been applied at the German Aerospace Center to a simulator for the Diamond DA42 aircraft model.
In contrast to pure cockpit procedure training, the robot’s freedom of motion is not only capable of representing the simulated flight motions visually, it can also realistically transmit the corresponding changes in position and motion. In DGWorld’s standard flight simulators, the virtual environment is depicted directly using two HD-quality projectors that display images on the inside of the closed cabin dome. Thus, pilots can also train for multiple-risk situations which are not only time-consuming for training aircraft and helicopters they are also too dangerous to perform in a real aircraft. Thanks to the possibility of simulating even extreme rolling and pitching motions, extraordinary flight maneuvers, such as inverted flight, in which the pilot flies upside-down, can be represented without difficulty. The pilot can train for critical situations over and over again, and the simulated flights can be followed live in the training rooms and quickly reconstructed.
SimBOT -Simulator unique control platform integrates all components with safety implications in the simulator room into a common high-performance control system. Moreover, the modularly designed software and hardware offer very good integration options for different components. The use of high-performance industry standards, such as Ethernet and ProfiNet, make real-time communication possible between the control modules. The tried and tested control technology combines motion monitoring, process control and safety technology in a single system. Furthermore, redundant function tests are performed that guarantee the highest standard of stability and availability.
Projections are monitored continuously through an integrated camera system, and any necessary adaptations are performed automatically in real time, which gives the observer an extremely realistic image of the environment. Virtual worlds can thus be experienced without additional aids, such as 3-D glasses, and recordings (e.g., from the cockpit of a helicopter) can even be reproduced and logged in the highest quality. Every DLP projector provides a light intensity of around 1000 lumens with excellent WQXGA resolution (2560x1600 pixels).
The projectors are also equipped with new cluster- LEDs in which the active LED surface is divided into several fields.
