Autonomous automobile technology is a rapidly developing field, with interest in both academia and industry. Outdoor navigation of autonomous vehicles, especially for roughterrain driving, has already been a new research focus. DARPA Grand Challenge and LAGR program stand for the top development level in this research region. Rough-terrain driving research offers a challenge that the in-vehicle...

To describe the skid resistance attenuation of asphalt pavement during its life cycle, this paper selected a multi-variable accelerated abrasion machine to simulate process, and British Pendulum Number was evaluate after various abrasive cycles. During three factors influencing were considered, including aggregate types (diorite, limestone, granite, basalt), nominal maximum size (NMAS), gradati...

Public opinion has become increasingly critical of current logging methods and technologies, there is a demand for standards to guide the operations environmentally impactful industries. For many years, numerous researchers have studied impact on forest soils, revealing that high risk damaging soil during terrain transport. Here we analyse review total 105 publications in this area. This large ...

The Adaptable Monitoring Package (AMP), along with a remotely operated vehicle (ROV) and custom tool skid, is being developed to support near-field (≤10 meters) monitoring of hydrokinetic energy converters. The AMP is intended to support a wide range of environmental monitoring in harsh oceanographic conditions, at a cost in line with other aspects of technology demonstrations. This paper, whic...

Skid-steered wheeled vehicles are commonly adopted in outdoor environments with the benefits of mobility and flexible structure. However, different from Ackerman turning vehicles, skid-steered do not possess geometric constraint but only dynamic when steered, which leads to motion control state estimation problems for vehicles. The controlling accuracy a vehicle depends largely on feedback info...
