DE4402129A1 - Movement and positioning device for computer simulation system - Google Patents

Abstract

The device consists of a hollow sphere on rollers movable in any axis and in predefined positions. The sphere is supported on freely rotating rollers. It is moved by a friction wheel rotated by a servo motor. The axis of the wheel is turned to provide a 3D motion. Motion may be measured by integral position encoders. An individual is seated within the enclosed sphere. Within the sphere is a VDU that is part of a computer simulation system.

Description

In certain areas of technology it is necessary body to bring them into predetermined, defined positions, as well as other positions from these positions drive. Likewise, it may be necessary to use these different Positions using different types of movement (e.g. uniform or non-uniform accelerated). The possibility of realistically reproducing these movements is, for example, a criterion for the authenticity of a Simulation of driving and flight simulators.

It's difficult here rig, the movements and accelerations that occur in practice attitudes to which the human body is exposed emulate the simulator. It gets even more complicated with complex movements, such as B. (multiple) rollovers gene.

With the invention presented here, these problems, depending on the application, be minimized or eliminated.

The basic idea of the offered solution is one on ball rollers or sliding hollow ball that rotates becomes. Inside this sphere, through an opening or Any body can be reached with an entry be held by means of holding devices. Should be a human be positioned in the ball, so it can be on an ent speaking seat be strapped. The ball will now after the opening was closed, over at least one Friction wheel, which presses against its outer surface, in one turn movement.

This friction wheel is driven by an electric motor and forms the actual drive with it. This in turn is mounted so that it can rotate radially. The drive is rotated radially via a gearbox and a servomotor ( Fig. 1). By combining the drive movement and position adjustment of the drive, the ball can now be brought into any position. Depending on the type and parameterization of the drive and variable motor, different types of movement and accelerations are possible.

Is used for position detection e.g. If, for example, an incremental displacement sensor (similar to a trackball) or an absolutely working telemetry system is used in the interior of the sphere, coordinates can be approached ( Fig. 2).

If bodies are arranged eccentrically within the sphere, the acceleration of these bodies can be varied within wide limits by changing the rotational speed of the sphere. By shifting a corresponding counterweight in the opposite direction, the "overall ball system" can be kept calm. The body and counterweight can be positioned eccentrically and automatically ( Fig. 3).

For the control and parameterization of the drives, the comm nication inside / outside or creating a virtual re ality in the interior of the sphere, would be the use of a or multiple computers makes sense.

The constructive execution of the ball, its storage, its approach drive and the interior design depends on the concrete Use case. Execution of the construction from metal, art fabric or plexiglass is possible.

The following commercial applications are possible:
In areas in which the human being is the target, there are applications that are related to:

• - driving and flight simulators ( Fig. 4),
• - Computer simulation processes (cyberspace), as well
• - certain forms of diagnosis and therapy in medical and / or neurological area (radiation / computertomo graph).

Other applications would be in the area:

• - show,
• - showroom,
• - Game,
• - advertising and
• - teaching aids

conceivable.

For example, in a clear plexiglass gel models or any other objects purposes in all directions.
