This paper presents a vehicle autonomous localization method in local area of coal mine tunnel based on vision sensors and ultrasonic sensors. Barcode tags are deployed in pairs on both sides of the tunnel walls at certain intervals as artificial landmarks. The barcode coding is designed based on UPC-A code. The global coordinates of the upper left inner corner point of the feature frame of eac...

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.

The objective of this paper is to show how PHM concepts can be included in the design of an autonomous Unmanned Air Vehicle (UAV) and in doing so, provide effective diagnostic/prognostic capabilities during system operation. The authors propose a PHM Cycle that is divided into two parts, covering the design of the Autonomous PHM system and the operation of the PHM system in real-time applicatio...

Autonomous vehicles are being viewed with scepticism in their ability to improve safety and the driving experience. A critical issue with automated driving at this stage of its development is that it is not yet reliable and safe. When automated driving fails, or is limited, the autonomous mode disengages and the drivers are expected to resume manual driving. For this transition to occur safely,...
