DLR VR-SCAN: A versatile and robust miniaturized laser scanner for short range 3D-modelling and exploration in robotics

Abstract

Precise and robust perception of the environment is crucial for highly integrated and autonomous robot systems. In this paper the dedicated design of a triangulation based laser range scanner optimized for 3D-modelling and autonomous exploration in robotics is presented. The presented 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. The design considerations and a prototype are described and experimental results are presented.
