Blade control in Cartesian space for leveling work by bulldozer
Abstract This paper proposes an automatic blade control system in a Cartesian space for leveling of bulldozer blades, which controls the position of blade cutting edge to the position of design surface for leveling in a Cartesian space. To control the position of blade cutting edge in a Cartesian space, this paper developed a Cartesian-space control algorithm by applying a mathematical model of the homogeneous transformation matrix, based on a virtual spring-damper tucked between the blade cutting edge and design surface. After applying the proposed control system at an actual construction site, this paper compared the results with those of an expert operator and analyzes their accuracy and precision.
Highlights The automatic blade control system is proposed to automatically control the dozer blade. It is not easy even for an expert to operate a bulldozer. This system controls the position of a blade cutting edge in the Cartesian space. This control algorithm is based on Virtual Spring Damper-hypothesis. The proposed system performed more precise work than an expert operator.
