DLR VR-SCAN

A Versatile and Robust Miniaturized Laser Scanner for short range 3D-Modelling and Exploration in Robotics.

Precise and robust perception of the environment is crucial for autonomous robot systems. Various robotic tasks demand versatile perception. The DLR VR-SCAN is a dedicated design of a versatile triangulation based laser range scanner optimized for autonomous 3D-modelling and exploration in robotics.

The laser scanner design is based on an extremely small MEMS scan head permitting a compact, lightweight and highly integrated implementation allowing for hand-eye operation. Special capabilities like variable range and confidence rating of the measuring values increase robustness and versatility.
