This article presents an approach to improve and monitor the behavior of a skid-steering rover on rough terrains. An adaptive locomotion control generates speeds references to avoid slipping situations. An enhanced odometry provides a better estimation of the distance travelled. A probabilistic classification procedure provides an evaluation of the locomotion efficiency on-line, with a detectio...

Historically, research has shown that it is neither physically possible nor economically feasible to construct an asphalt concrete pavement surface that provides skid resistance at an adequate level throughout the pavement's service life. Consequently, engineers utilize a seal coat maintenance technique as one way of improving friction performance on roadways. This maintenance technique consist...

Heterogeneous systems provide variety in order to address unforeseen problems in unknown environments. This paper describes a series of custom-built robotic devices that employ heterogeneity as a means of achieving greater capability. From novel, crawling limbed/tracked hybrid robots to water hammer assisted actuation to macro/micro marsupial robot teams, commonalities are investigated to move ...

This paper suggests a new way for nonholonomic mobile robots to navigate in obstacle environments using potential fields based on navigation functions. The proposed strategy is a time-invariant feedback control design with the distinguishing feature that it requires almost no switching compared to alternative methodologies of the same nature. Asymptotic convergence with collision avoidance for ...

The paper presents a localization system for a mobile robot using the vision system and LED markers and considers the problem of velocity and acceleration estimation in the case of planar motions. Theoretical considerations include the principle of measurement and the details of Kalman estimator with illustrations based on experimental setup. The presented measurement system can be used for a r...

The term “nanoparticles” refers to very tiny particles, much smaller than cancer cells or even standard chemotherapy drugs. A nanoparticle ranges between 1 and 100 nanometers (a metric unit of length equal to one billionth of a meter) in diameter. Nanoparticles have industrial uses in creating surface coatings for scratch-resistant glass, skid-resistant roads, in strengthening metals, and in th...

Skidding operations can cause considerable and wide spread soil disturbance. The objective of this study was to evaluate the effects of ground skidding operations on soil compaction, moisture content, and total porosity at different levels of slope and traffic frequency. Four levels of traffic intensity (3, 8, 13, and >13 passes of a Crawler Tractor Onezhets ? 110) and three levels of slope ( ...
