- When I searched in the library computer, I came across following record:
-
- "Title: Mobile robot map making using sonar.
- Author: Zelinsky, A.
- Corporate Source: Univ of Wollongong, Wollongong, Aust
- Source: Journal of Robotic Systems v 8 n 5 Oct 1991 p 557-577
- CODEN: JRSYDB ISSN: 0741-2223"
-
- The abstract describes that the article deals with a method of producing high-
- resolution maps of an indoor environment. The method is based on investigating
- straight line segments extracted from the sonar range data describing obstacles
- near the robot. The mobile robot then moves parallel to the straight line sonar
- segments, in close proximity to the obstacles, continually applying sonar
- barrier test. This determines whether or not a sonar line segment is a true
- obstacle edge or a false reflection.
-
- Sounds interesting, doesn't it? Unfortunately I don't have access to this
- publication myself. Would anyone who has, like to reply to me?
