The number of pet health plans delivered by veterinary surgeons has increased significantly over the past 10 years in both small animal and equine practice. They offer many benefits for both the client and the practice, but require careful planning if they are to be implemented successfully. In this article, John Goulding provides an overview of the benefits and difficulties associated with setting up and running a health plan, and describes some of the common models available.
Current approaches to determine the orientation and maintain balance of mobile robots typically rely on gyro and tilt sensor data. This paper presents an image-based sensor fusion approach using sensed data from a MEMS gyro and a digital image processing system. The approach relies on the statistical property of man-made or cultural environments to exhibit predominately more horizontal and vertical edges than oblique edges. The gyro data and statistical image data is Kalman filtered to estimate the roll angle. The system was tested both indoors and outdoors at the University of Arizona campus, and it demonstrated continuous roll angle drift correction, without prior knowledge of or training on the environment. The algorithm was then implemented in a biped walking robot to demonstrate the real-time, end-to-end proof of concept.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
