Control of vehicle traction is of utmost importance in providing safety and obtaining desired vehicle motion in longitudinal and lateral vehicle control. Vehicle traction control systems can be designed to satisfy various objectives of a single vehicle system or a platoon of vehicles in an automated highway system, which include assuring ride quality and passenger comfort. Other objectives are ...

The purpose of the present study was to investigate whether genetic differences in muscle histochemical characteristics were related to the voluntary wheel-running activity level by using genetically fast-twitch fiber-dominant rats (FFDR) and control rats (CR). The rats were divided into four groups; sedentary CR (Sed-CR), wheel-running CR (WR-CR), sedentary FFDR (Sed-FFDR), and wheel-running F...

Our long-term goal is one of designing land-based vehicles to provide enhanced uneventerrain locomotion capabilities. In this paper, we examine and evaluate candidate articulated leg-wheel subsystem designs for use in such vehicle systems. The leg-wheel subsystem designs under consideration consist of disk wheels attached to the chassis through an articulated linkage containing multiple lower-p...

On-Line Optical Flow Feedback for Mobile Robot Localization/Navigation. (May 2003) David Kristin Sorensen, B.S., Texas A&M University Chair of Advisory Committee: Dr. Sooyong Lee Open-loop position estimation methods are commonly used in mobile robot applications. Their strength lies in the speed and simplicity with which an estimated position is determined. However, these methods can lead to i...

a study was conducted on genetics of some important agronomic traits (number of productive tillers per hill, plant height (cm), panicle length (cm), number of spikelets per panicle and 100-grain weight) in rice during 2012-13. two lines were crossed with five testers in line × tester fashion to produce 10 f1 hybrids. analysis of variance revealed significant differences among genotypes and cros...

This paper presents an experimental study of the electronic differential system with four-wheel, dual-rear in wheel motor independently driven an electric vehicle. It is worth bearing in mind that the electronic differential is a new technology used in electric vehicle technology and provides better balancing in curved paths. In addition, it is more lightweight than the mechanical differential ...

Inflatable wheels are a promising concept for longrange exploration of Mars as well as extremely rugged terrestrial terrains. This paper describes experimental studies that characterize the mobility of a single robotic inflatable wheel in terms of its ability to negotiate Mars-like cohesion-less soils, climb large discrete obstacles and endure the wear and tear caused by driving over kilometers...
