This paper presents a multi-ultrasonic-sensor system designed for Simultaneous Localization and Mapping (SLAM) on the open source robot Kobuki Turtlebot. The operating system used in this research project, Robot Operating System (ROS), is also an open source project initially released in 2007. Our system has reduced response time and lower cost than traditional laser sensors. It consists of 8 HY-SRF05...
This work describes a mobile system that has been developed to precisely and reliably carry out echolocation experiments (data collection) for later analysis. A Kobuki robot was used as a base unit, providing mobility and accurate odometry. Custom mounting hardware was designed for the robot to accommodate a laptop for controlling the robot, along with a Microsoft Kinect sensor and ultrasonic transducers...
Based on the analytic expressions given by T. Hasegawa, et al.. (J.Acoust. Soc. Am. 79(4) 927-931 1986) an integral for calculation of the radiation force on a plane absorbing target in spherically focused field is derived. For focused fields a general relation between acoustic power P and normal radiation force Fn, P=GFn is obtained from the integral. Numerical computation of the integral is carried...
