Virtual straightening of scraper conveyor based on the position and attitude solution of industrial robot model

Abstract The movement of the floating connecting mechanism between a hydraulic support and scraper conveyor is space movement; thus, when pushes conveyor, there an error actual distance theoretical moving distance. As result, cannot obtain straightness requirement. Therefore, law analyzed programmed into Unity3D to realize accurate pushing via support. Coal Seam + Equipment Joint Virtual Straightening System established, straightening method based on motion connection proposed as default system. In addition, simulation was performed complex coal seam floor, results demonstrate that average within 2–8 mm, in direct proportion fluctuation floor strike with high accuracy, more affected by subsidence terrain during than bulge terrain. And some conclusions are verified experiment. Based verification relevant conclusions, comparison analysis Longwall Automation Steering Committee (LASC) technology system shows accuracy LASC under conditions slightly less
