چکیده
This paper presents a characterization study of the Sick LMS 200 laser scanner. A number of parameters, such as operation time, data transfer rate, target surface properties, as well as the incidence angle, which may potentially affect the sensing performance, are investigated. A probabilistic range measurement model is built based on the experimental results. The paper also analyzes the mixed pixels problem of the scanner.

A stochastic environment modelling method for mobile robot by using 2-D laser scanner
A method of environment modeling is presented which is based on the stochastic approximation technique. The accurate modeling of geometric environment is in general diicult because of sensor noise, irregular shape of objects and possible change of its layout, and so on. To overcome the problem, the environment is represented in this paper as stochastic obstacle regions equipped with their own s...
متن کاملCharacterization of the Hokuyo URG-04LX Laser Rangefinder for Mobile Robot Obstacle Negotiation
This paper presents a characterization study of the Hokuyo URG-04LX scanning laser rangefinder (LRF). The Hokuyo LRF is similar in function to the Sick LRF, which has been the de-facto standard range sensor for mobile robot obstacle avoidance and mapping applications for the last decade. Problems with the Sick LRF are its relatively large size, weight, and power consumption, allowing its use on...

Mobile robots that consist of a mobile platform with one or many manipulators mounted on it are of great interest in a number of applications. Combination of platform and manipulator causes robot operates in extended work space. The analysis of these systems includes kinematics redundancy that makes more complicated problem. However, it gives more feasibility to robotic systems because of the e...
متن کاملLaser Intensity-Based Obstacle Detection and Tracking
One of the major challenges in designing intelligent vehicles capable of autonomous travel on highways is reliable obstacle detection. Highways present an unknown and dynamic environment with real-time constraints. In addition, the high speeds of travel force a system to detect objects at long ranges. Because of its necessity for mobile robot platforms and intelligent vehicles, there has been a...
