Mining Robotics
(Springer, 2016)This chapter presents an overview of the state of the art in mining robotics, from surface to underground applications, and beyond. Mining is the practice of extracting resources for utilitarian purposes. Today, the ... -
Mobile LiDAR-Based Convergence Detection in Underground Tunnel Environments
(2017-04-06)This paper presents a mobile LiDAR-based method for remotely identifying convergence (i.e., naturally occurring deformation) in excavated underground tunnel environments. A mobile LiDAR system is used to collect and generate ... -
On the Design and Selection of Vehicle Coordination Policies for Underground Mine Production Ramps
(2016-02-23)Traffic management in underground mines, especially on production ramps, is a difficult problem to optimize and control. Most operations use one of a few common policies; e.g., the so-called “lock-out” and “loaded-vehicle ... -
Registration of Noisy Point Clouds Using Virtual Interest Points
(2016-03-04)A new method is presented for robustly and efficiently registering two noisy point clouds. The registration is driven by establishing correspondences of virtual interest points, which do not exist in the original point ... -
Towards Controlling Bucket Fill Factor in Robotic Excavation by Learning Admittance Control Setpoints
(2017-09-30)This paper investigates the extension of an admittance control scheme to- ward learning and adaptation of its setpoints to achieve controllable bucket fill factor for robotic excavation of fragmented rock. A previously ... -
Towards Extracting Absolute Roughness From Underground Mine Drift Profile Data
(2016-03-08)The purpose of this paper is to demonstrate a technique to utilize underground mine drift profile data for estimating absolute roughness of an underground mine drift in order to implement the Darcy-Weisbach equation for ... -
Towards Intensity-Augmented SLAM with LiDAR and ToF Sensors
(2016-02-24)Although passive sensors are widely used for many mobile robotics applications that perform mapping and localization functions, there are many environments (e.g., mining and planetary) where active sensors are more practical. ... -
Two Dimensional Axis Mapping using LIDAR
(2016-02-04)Abstract—This paper introduces two-dimensional axis mapping, which estimates axis maps (AMs) based on LiDAR measurements. An AM describes the dominant orientations of surfaces in an environment, and is void of positional ... -
Visual Indoor Positioning with a Single Camera Using PnP
(2016-02-23)This paper introduces an accurate and inexpensive method for localizing a calibrated monocular camera in 3D indoor environments. The objective of this work is to localize in 6 degrees-of-freedom (6 DOF) in the presence of ...
