The paper deals with the navigation system of a hybrid service robot intended for outdoor applications. The system uses different navigation sensors depending the current situation and task being done. The main sensors are laser range finder, GPS and heading gyro.
To know the pose of the robot is one of the central requirements in many applications. A localization algorithm should be robust, it should give the estimate of unreliability and it should be able to recover from errors. The above requirements are often trade offs with the computational complexity. This paper presents a global localization algorithm that… (More)
This paper presents a system for measuring three dimensional surface map of steel billets. The proposed system is used for quality control of the surfaces of the billets. The system is based on camera and a laser stripe generator. The billet is moved in front of the inspection system with an external moving mechanism. Triangulation is used for measuring the… (More)
