APPROACH TO CONTROL METHOD OF PLANNING LEVEL FOR EXCAVATING ROBOT
Qian, Sun Shou,Ming, Xu Hai,Jun, Wang Yi,Liang, He Bao 대한전자공학회 1992 HICEC:Harbin International Conference on Electroni Vol.1 No.1
The method of path planning and trajectory planning are studied. The control of planning level for whole work cycle process and excavating process based on predetermined path and force monitor is realized on an experimental prototype. The software of three dimensional dynamic simulation is developed to examine the control method of planning level.

The extraction parameters of intracellular polysaccharide (IPS) from Pleurotus citrinopileatus SM-01mycelia were optimized, and the in vitro and in vivo antioxidant activities of IPS were investigated. The optimum conditions of IPS extraction were predicted to be an ultrasonic treatment time of 664.09 s, precipitation time of 23.03h and pH 7.36, and IPS yield was estimated at 16.13%. The in vitro inhibition effects of IPS at a dosage of 5 g/L on the superoxide anion, 1,1-diphenyl-2-picrylhydrazyl (DPPH) and hydroxyl radicals were 73.96±4.62%, 69.2±4.37%,and 50.75±4.39%, respectively, which were 72.56±5.08%, 22.83±1.94%, and 43.93±3.26% higher than that of butylated hydroxytoluene (BHT), respectively. The reducing power of IPS was 0.9±0.07, 69.81±5.24% higher than that of BHT. The activities of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), catalase (CAT) and alanine aminotransferase (ALT) in mice blood were 241.38±23.19, 454.95±42.39, 60.32±5.16, and 32.39±2.54 U/mL,respectively, and the malonaldehyde (MDA) level was 9.54±0.72 nmol/mL. The results provided a reference for the large-scale extraction of IPS by P. citrinopileatus SM-01 in industrial fermentation, suggesting that the IPS can be used as a potential antioxidant, which enhances adaptive immune responses.
