Pressure vessels are widely used in industrial fields, and some of them are safety-critical components in the system-for example, those which contain flammable or explosive material. Therefore, the pressure of these vessels becomes one of the critical measurements for operational management. In the paper, we introduce a new approach to the design of non-intrusive pressure sensors, based on ultr...

The blind and visually impaired people are facing a number of challenges in their daily life. One of the major challenges is finding their way both indoor and outdoor. For this reason, routing and navigation independently, especially in urban areas are important for the blind. Most of the blind undertake route finding and navigation with the help of a guide. In addition, other tools such as a c...

In this chapter, a Reconfigurable Ultrasonic Smart Sensor Platform (RUSSP) for real-time signal analysis and image processing is presented. The RUSSP is designed to facilitate the development and implementation of ultrasonic signal processing algorithms with embedded software and reconfigurable hardware. It provides the opportunity to explore the full design space including software only, hardw...

In this paper, we propose a navigation algorithm for a mobile robot, which is intelligently searching the goal location in unknown dynamic environments using an ultrasonic sensor. Instead of using "sensor fusion" method which generates the trajectory of a robot based upon the environment model and sensory data, "command fusion" method is used to govern the robot motions. The navigation strategy...

In the last several years, mobile manipulators have been increasingly utilized and developed from a theoretical viewpoint as well as for practical applications in space, underwater, construction, and service environments. Our mobile manipulator RISCbot, is comprised of a manipulator arm mounted on a motorized mobile base wheelchair. The work presented in this chapter explores the use of multi-s...

This work aimed to contribute to the modelling of slurry flows in horizontal pipes supported by experimental data gathered in a well instruments pilot rig. An ultrasonic sensor system was inserted in the pipe in order to calculate the slurry velocity profiles using a time domain correlation method. Effects of particles concentrations and slurry flow rates were investigated. A comparison of the ...

The objective of this paper is to build a map using a quadrocopter. To explore the surroundings and build a map, ultrasonic sensors and a camera sensor are used. As ultrasonic and camera sensors get information separately, they have to be synchronized. Through this synchronization, the location of the quadrocopter can be recognized. At that point, the four horizontal distances can be calculated...

The paper describes a new method and system, designed for application to upper extremity prosthesis. Artificial limb with our new system is robot arm controlled by EMG signals and monitored and corrected by set of ultrasonic sensors. The control system used to control robotic arms measured EMG signals from muscles and the signal from the ultrasonic sensors detect obstacles in the robot's motion...

Control method for moving robotics in closed areas based on creation and sharing maps through shortest path findings and obstacle avoidance is proposed. Through simulation study, a validity of the proposed method is confirmed. Furthermore, the effect of map sharing among robotics is also confirmed together with obstacle avoidance with cameras and ultrasonic sensors. Keywords-domestic robotics; ...
