A localization method based on omni-directional ultrasonic sensing is proposed in this paper, circumventing the detection-angle limitation of ultrasonic signals. Experiment setup includes four ultrasonic sensors located on the vertexes in a square environment serving as receivers and a mobile robot carrying an omni-directional ultrasonic device as a transmitter. Each ultrasonic sensor is integrated...
In this paper, an ultrasonic-based localization using ultrasonic reflection method is proposed. Experiment environment includes a mobile robot and four poles forming a square around the measuring site. Ultrasonic sensors built on the poles serve as receivers and the mobile robot serves as a transmitter, and all ultrasonic sensors are integrated with their Zig-Bee modules. By the sequential ultrasonic...
