“…The Finnish company Plustsh integrated walk technique into timber production machinery by creating a six-legged timber production machine. The development of multitasking timber harvesters operating in timber production areas not only boosted production efficiency and guaranteed the safety of the workers but also brought an indispensable impetus to the economic development [6][7][8][9][10][11].…”

A reconfigurable logging and branch-lopping mechanism has been designed to shorten the production cycle, reduce work intensity, and improve labor survival rate in the logging industry. The mechanism integrating logging and branch-lopping functions can flexibly morph into three con-figurations, namely, series, parallel and mixed, as well as eight structure states to satiate different requirements. Not only does it possess sufficient stiffness to fell large trees but it also offers high flexibility to trim and crop small branches which superior performance has relatively wide engineering application prospects. The kinematics and static stiffness of the mechanism are the key techniques for its engineering application. With the mechanism as the research object, the working principles were analysed and the adjacency matrix of each structure state was presented. The Screw Theory and CGK formula were deployed to calculate the degrees of freedom of some of the structure mechanisms. The kinematics of some of the structure states was analysed and their flexibility matrices were obtained with vector algebra. The static stiffness of two structure states was compared indirectly by contrasting their flexibility matrices before their kinematics was simulated numerically. Engineering application of the mechanism in welding robots, robots that pick up objects, cleaning robots and other fields is demonstrated towards the end of this paper.

The study considers the problem of constructing routes for the export of timber. The task reduced to building a rooted tree. The study presents two approximate algorithms for solving the problem of covering polygons with rooted trees. To simplify the task, the polygon is covered with a square grid. A greedy algorithm is described that should give an approximate solution. The article also describes the branch and bound method with a reduced number of iteration options. We have reduced the number of iterations by using a special way of building links.
