In this paper, we developed a control system which can make the intelligent robotic excavator perform excavating operation autonomously. It can recognize the excavating targets by itself, program the operation automatically based on the original parameter, and finish all the tasks. Experimental results indicate the validity in real-time performance and precision of the control system. The intelligent robotic excavator can remarkably ease the labor intensity and enhance the working efficiency.展开更多

And disastrous accidents on unexpected collapse and landslide along bed plane probably occurred. Based on the stochastic medium theory and the methods for predicting ground point’s movements and deformations in any direction under folding structure strata and any shape rooms, the basic factors in varied geology and excavating were comprehensively analyzed. The formulas for predicting ground point’s movements and deformations were derived under excavating underground non-bedded shape rooms. Because the formulas for predicting surface subsidence can’t be integrated, the numerical integral method and the computer technique were adopted to calculate the values of integral equations.展开更多
