Communications __________________ _ Obstacle a Voidance with Ultrasonic Sensors
A mobile robot system, capable of performing various tasks for the physically disabled, has been developed. To avoid collision with unexpected obstacles, the mobile robot uses ultrasonic range finders for detection and mapping. The obstacle avoidance strategy used for this robot is described. Since this strategy depends heavily on the performance of the ultrasonic range finders, these sensors a...
متن کاملAnalysis of Vehicle Detection with WSN-Based Ultrasonic Sensors
Existing traffic information acquisition systems suffer from high cost and low scalability. To address these problems, the application of wireless sensor networks (WSNs) has been studied, as WSN-based systems are highly scalable and have a low cost of installing and replacing the systems. Magnetic, acoustic and accelerometer sensors have been considered for WSN-based traffic surveillance, but t...
متن کاملWhen Ultrasonic Sensors and Computer Vision Join Forces for Efficient Obstacle Detection and Recognition
In the most recent report published by the World Health Organization concerning people with visual disabilities it is highlighted that by the year 2020, worldwide, the number of completely blind people will reach 75 million, while the number of visually impaired (VI) people will rise to 250 million. Within this context, the development of dedicated electronic travel aid (ETA) systems, able to i...
متن کاملObstacle Detection and Collision Avoidance Using Ultrasonic Distance Sensors for an Autonomous Quadrocopter
A simple approach for obstacle detection and collision avoidance of an autonomous flying quadrocopter using low-cost ultrasonic sensors and simple data fusion is presented here. The approach has been implemented and tested in a self-developed quadrocopter (Figure 1) and its evaluation shows the general realizability as well as the drawbacks of this approach. The presented approach is intended t...
