Error eliminating rapid ultrasonic firing for mobile robot obstacle avoidance

This paper introduces error eliminating rapid ultrasonic firing (EERUF), a new method for firing multiple ultrasonic sensors in mobile robot applications. EERUF allows ultrasonic sensors to fire at rates that are five to ten times faster than those customary in conventional applications. This is possible because EERUF reduces the number of erroneous readings due to ultrasonic noise by one to tw...

Moving Domestic Robotics Control Method Based on Creating and Sharing Maps with Shortest Path Findings and Obstacle Avoidance

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; ...

Measurement of Angular Position of a Mobile Robot Using Ultrasonic Sensors

Ultrasonic sensors are commonly used in robotics for range measurement in obstacle detection and avoidance systems. They have also been used for localization by map matching techniques. This paper presents a novel use of ultrasonic sensors for the measurement of angular position of a mobile robot relative to a known ultrasonic source. The method is based on measurement of the phase difference o...
