This paper presents an algorithm for extending RS paths for a robot with both front and rear wheel steer. We call such robots as FR steer. The occurrence of such paths is due to the additional maneuver possible in such a robot which we call parallel steer, in addition to the ones already present in a vehicle with only front wheel steering. Hence we extend the optimal path set Λ, containing only...
Horizontal strain at the bottom of asphalt concrete due to repeated traffic loads is the most critical parameter in characterizing fatigue performance of flexible pavement. The study of horizontal strain is thus very important to understand the strain behavior, predict the fatigue life and implement in design and analysis. A total of twelve Horizontal Asphalt Strain Gages (HASGs), six gages ori...
In this paper, we introduce a new class of estimators of the Hurst exponent of the fractional Brownian motion (fBm) process. These estimators are based on sample expectiles of discrete variations of a sample path of the fBm process. In order to derive the statistical properties of the proposed estimators, we establish asymptotic results for sample expectiles of subordinated stationary Gaussian ...
In this paper, we examine optimal path planning for the motion of a wheel which minimizes some combination of time and effort expended. Several techniques are examined but a combination of continuation and multi-dimensional N ewton-Raphson shooting is shown to be effective, within limits.
Authors have been conducting research on an autonomous system for loading operation by wheel loader. In loading operation with V shape loading method, a time for travelling is the dominant factor for the cycle time. The path should be modified varied condition of the working place. To achieve quicker and reliable operation in autonomous loading operation, new path planning method is developed. ...
To improve the accuracy and robustness of inertial navigation systems (INS) for wheeled robots without adding additional component cost, we propose Wheel-INS, a complete dead reckoning (DR) solution based on wheel-mounted microelectromechanical system (MEMS) measurement unit (IMU) in this article. There are two major advantages mounting IMU to center non-steering wheel. Firstly, gyroscope outpu...
Direct Yaw moment Control systems (DYC) can maintain the vehicle in the driver’s desired path by distributing the asymmetric longitudinal forces and the generation of the Control Yaw Moment (CYM). In order to achieve the superior control performance, intelligent usage of lateral forces is also required. The lateral wheel forces have an indirect effect on the CYM and based upon their directions,...
The question of whether ‘‘we drive as we live’’ or whether ‘‘we are transformed behind the wheel’’ generates discussion at all levels from the scholarly to the popular. To shed light on this issue, this study measured the personality traits of general anger and driving anger and four modes of expression common to both contexts (verbal, physical, displaced and adaptive) in a sample of 198 driver...
The purpose of this study was to evaluate the effects of early-life exercise on adult physical activity (wheel running, home-cage activity), body mass, food consumption, and circulating leptin levels in males from four replicate lines of mice selectively bred for high voluntary wheel running (High Runner or HR) and their four non-selected control (C) lines. Half of the mice were given wheel acc...
Physical properties of terrains encountered by the Curiosity rover during the first 360 sols of operations have been inferred from analysis of the scour zones produced by Sky Crane Landing System engine plumes, wheel touch down dynamics, pits produced by Chemical Camera (ChemCam) laser shots, rover wheel traverses over rocks, the extent of sinkage into soils, and the magnitude and sign of rover...
