The Colorado School of Mines

The Colorado School of Mines (CSM) is a public teaching and research university devoted to engineering and applied science, with special expertise in the development and stewardship of the Earth's natural resources. Located in the small town of Golden, Colorado, CSM was ranked 77th in America among national universities in 2009, and admission is selective.

Design and Implementation of a Remote Control System for Teleoperation of a Skid-Steer Loader over a Wi-Fi Mesh Network Christopher Meehan1, Kevin Moore1, 2, John Steele1, 2 , Manoja Weiss 1: Department of Engineering Colorado School of Mines 2: CARDI - Center for Automation, Robotics, and Distributed Intelligence Motivation Teleoperated Skid Steer Loader Testing Search and rescue efforts within an underground mine are very dangerous, cumbersome, and slow. Background Implementation AMR – Autonomous Mobile Radio An autonomous vehicle (golf cart) that repositions itself to relay wireless information in the most efficient manner. Each vehicle is equipped with a Rajant (Breadcrumb ME2) Wi-Fi mesh node. Rajant Wi-Fi nodes are capable of automatically reconfiguring based upon the signals strengths from peer nodes. Conclusions Mobile Wi-Fi Mesh Network Teleoperated vehicles would be a great assistance to search and rescue workers and would keep people out of harms way. An underground mine is a challenging environment for transmitting high bandwidth data across long ranges. Cables have been used in the past for carrying data, but they are too troublesome and risky for moving vehicles. The communications problem can be solved by relaying information across multiple nodes. Additionally, mobile relays could move to the best location to relay wireless signals and move with the teleoperated vehicle to provide coverage. Unfortunately, the B...

imaging a complex Earth… …with all available information… …to derive rock properties… …in a stochastic environment Good morning everyone. I would like to start by thanking you for visiting us at CSM and for giving me the opportunity to present to you some interesting leading-edge research ideas that we are working on here at CSM. The common theme of my presentation is that of complexity of the Earth we are trying to image. This idea of imaging a complex Earth in itself, is not new. The novelty consists in the techniques developed to address this problem, and in this context I would like to highlight 3 main ideas: First, imaging a complex Earth requires use of all data available to us; Second, a useful seismic image addresses questions of lithology and not only structure; Third, we need to characterize our data from a stochastic point of view, as opposed to the deterministic point of view, which is the prevalent approach today.
