In the last few years, automatic guidance of agricultural vehicles has received increased interest to improve field efficiency, while releasing human workers from monotonous operations. this context, work proposes a short or medium-term alternative complete automation manual harvesting processes by introducing fleet robotic N-trailer support crop transportation task. With aim coordinate several...

In this paper various design techniques are applied to the trajectory tracking problem for a mobile robot with trailers. Using simulations and experiments, we evaluate linear and nonlinear designs on the basis of implementation issues, stability and performance. After a careful design of their gains, the various feedback controllers have very close performance measures. In both the simulations ...

Timber transport in the forest is a very complex operation, and expensive from an energy point of view. Furthermore, in some cases, this operation can be very difficult and dangerous in unfavorable conditions of the road surface, which mainly occur in winter (frozen ground) and in spring (muddy ground). The goal of this study was to develop an innovative transmission hydraulic control system fo...
