MUNOZ, Paula Andrea; IMBACHI, Sandra Carolina  e  FLOREZ, Juan Fernando. Obstacle detection system with Scanner. Ing. Desarro. [online]. 2014, vol.32, n.2, pp.200-217. ISSN 0122-3461.

This paper presents the design, implementation and validation of a laser system for 2D detection of obstacles, indoors and outdoors, using laser radar of Allen Bradley Company (Scanner Safe Zone Laser Multizone). A method for deduction of data frames between the laser radar equipment and proprietary software Safety Configuration & Diagnostic is proposed. We communicate the laser radar with Player software, enabling its use for robotic applications. We design and implement a software system that lets you use the obstacles 2D coordinates scanned by the laser radar, both text and graphics form, allowing to use it in other applications without limitation. The system is validated tests to measure distances in indoor and outdoor, outdoor obtaining as results, between 94 cm and 5120 cm, an average error of 3.32 cm and interior, between 30 cm and 1500 cm, an error through 0.93 cm.
