Wheelchair racing is an important modality in the rehabilitation of people with mobility impairments; thus, it plays a significant role in the lives of many wheelchair users. This paper presents simple roll stability analyses for three- and four-wheeled rider/racing wheelchair systems during turning maneuvers. The results suggest that three-wheeled systems may be less stable than four-wheeled s...

The purpose of this chapter is to introduce, analyze, and compare the models of wheeled mobile robots (WMR) and to present several realizations and commonly encountered designs. The mobility of WMR is discussed on the basis of the kinematic constraints resulting from the pure rolling conditions at the contact points between the wheels and the ground. According to this discussion it is shown tha...

This paper considers the influence of hydrodynamic processes in movement free surface liquid partially filled tractor tanks. Splashing containers is a significant problem study functional stability marine, aerospace, rail, and automotive industries. After all, it affects productivity traffic safety. The same effect was observed when performing transportation work while delivering cargoes agricu...

The machine-tractor fleet of enterprises is an important link in the production products various branches industry Ukraine. timely performance transport, agricultural, road construction and other works, ultimately cost or services, largely depend on its effective work. Rolling bearings are one most common technical devices used machines. They determine reliability devices. resource tractor chas...

New technologies have a potential to contribute to achieving significant economic, social and environmental benefits in agriculture sector. However, the adoption of Information and Communication Technologies (ICT) have encountered some difficulties among farmers. This paper reports investigations on the adoption of ICT in agriculture among Italian tractors users and explores their opinions on t...

In this paper, the important formation control problem of nonholonomic wheeled mobile robots is investigated via a leader-follower strategy. To this end, the dynamics model of the considered wheeled mobile robot is derived using Lagrange equations of motion. Then, using ADAMS multi-body simulation software, the obtained dynamics of the wheeled system in MATLAB software is verified. After that, ...

predicting the maintenance and management costs and replacement age of tractors in agricultural mechanized units, is important from several points. so, doing a timely agricultural operations, more accurate measure of the amount of income  including the cost of these items , determining the useful life of old tractors , replacement age, cost of the process changes and the possibility of examinin...

Connecting COTS (Commercial-off-the-Self) simulation packages entails various difficulties. First of all, commercially available simulation packages hide the access to some internal data that is needed to connect to other simulation models in the distributed simulation study. Next, the data sharing between simulation models is complicated. In order to carry out distributed simulation studies ap...
