Description
The Virtual Reality Lab – the so-called CAVE – is an immersive, interactive 3D test environment.
The projection consists of seven elements in an 180° arrangement. Each element has a width of 1.52 m and a height of 2.03 m; in addition, a 40 cm base. The overall projection thus has an area of 21.6 m².
To give a spatial impression, the projection is stereoscopic. Each of the seven elements is illuminated by two projectors. A projector generates the image for the right and the other the image for the left eye. For the separation of the images linear polarization filters are used, mounted on the projectors. The viewer gets a pair of glasses with two different polarized glasses, so that he sees a 3D image with depth information.
An omnidirectional treadmill (Omnideck), which is located in the center between the projection screens, allows free and unlimited movement in the virtual world and can thus increase immersion. It can be used with a VR headset or in combination with the projection screens.

Virtual Crater
The Virtual Reality Lab was originally set up within the project Virtual Crater. The goal of this project was to develop a virtual test environment (virtual testbed) in which it is possible to program, test, and optimize robot systems in a realistically simulated lunar crater at low cost.
Currently, the VR-Lab serves as an interactive and immersive control station for semi-autonomous robots, which can visualize the robots' maps, i.e., their environment, in three dimensions and enable monitoring and control of the systems.
