The design and implementation of a laser range-finder array for robotics applications
We introduce the concept of using a laser range finder array to measure height and tilt for mobile robotics applications. We then present a robust, scalable algorithm for extracting height and tilt measurements from the range finder data. We calibrate the sensors using a precision two-axis system, …
