An autonomous mobile vehicle for indoor environment is described. The vehicle is based on three subsystems: a visual self-location module to determine vehicle location; an ultra-sonic based module for obstacle avoidance and a visual module to permit the vehicle to cross safety the doors. The prototypal vehicle is currently under test in our laboratory.

In this paper an experimental platform developed for the ESPRIT project MARIE is described. The vehicle has an automobile-like kinematics and is fitted with a control computer and ultra-sonic sensors. The control software has a layered, modular structure and standardized interfaces, suitable for an experimental platform. The principal software modules and the experiments performed to test the i...

The present state research overviews on the use of ultrasonic vibrations in press joints. main effect occurring ultra-sonic activation for pressed parts is friction force break. works investigating ultrasound various materials, as well application this pressing are viewed article.

Practical aspects of motion generation and control for parking a nonholonomic autonomous vehicle are considered. An iterative algorithm for the parallel parking maneuver is proposed. It is based on ultra-sonic range data processing. To control the steering angle and longitudinal velocity of the vehicle during the parking maneuver, sinusoidal reference functions are used. To prevent collisions, ...

In this paper we present a new technique for on-line extraction of natural landmarks using ultra sonic sensors mounted on a mobile platform. By storing landmarks' positions in a reference map, we can easily achieve absolute localization in an indoor environment by doing matching between recently collected landmarks and the reference map. The matching procedure also takes advantage of compass re...
