Trajectory planning and base attitude restoration of dual-arm free-floating space robot by enhanced bidirectional

Zongwu XIE1 , Xiaoyu ZHAO1 , Zainan JIANG1 , Haitao YANG2 , Chongyang LI1

Frontiers of Mechanical Engineering 2022, Volume 17, Issue 1, doi: 10.1007/s11465-021-0658-y

Abstract: When free-floating space robots perform space tasks, the satellite base attitude is disturbed by the dynamic coupling. The disturbance of the base orientation may affect the communication between the space robot and the control center on earth. In this paper, the enhanced bidirectional approach is proposed to plan the manipulator trajectory and eliminate the final base attitude variation. A novel acceleration level state equation for the nonholonomic problem is proposed, and a new intermediate variable-based Lyapunov function is derived and solved for smooth joint trajectory and restorable base trajectories. In the method, the state equation is first proposed for dual-arm robots with and without end constraints, and the system stability is analyzed to obtain the system input. The input modification further increases the system stability and simplifies the calculation complexity. Simulations are carried out in the end, and the proposed method is validated in minimizing final base attitude change and trajectory smoothness. Moreover, the minute internal force during the coordinated operation and the considerable computing efficiency increases the feasibility of the method during space tasks.

Restoration of hyper-eutrophic water with a modularized and air adjustable constructed submerged plant

Jinzhong LI, Xueju LI, Shujuan SUN, Xuegong LIU, Suiliang HUANG

Frontiers of Environmental Science & Engineering 2011, Volume 5, Issue 4,   Pages 573-584 doi: 10.1007/s11783-011-0363-x

Abstract: A modularized and air adjustable constructed submerged plant bed (CSPB) which can be used to restore the eutrophic water is introduced in this paper. This plant bed helps hydrophyte grow under poor conditions such as frequently changed water depth, impaired water transparency, algae bloom and substantial duckweed in summer, which are not naturally suitable for growing hydrophyte. This pilot study in Waihuan River of Tianjin, China, revealed that reduction of Chemical Oxygen Demand (COD), Total Nitrogen (TN) and Total Phosphorus (TP) by the use of CSPB could be reached 30%–35%, 35%–40%, 30%–40% respectively in the growing season (from March to October) and 5%–10%, 5%–15%, 7%–20% respectively in the winter (from November to February) when the detention time was 6 d. The relationships between the concentration of COD, TN, TP and the detention time fit the first-order kinetic equation well and the coefficients of determination ( ) were all above 0.9. The attenuation coefficients k of the kinetic equation were a function of the water temperature. When the water temperature was quite low or quite high, was not significantly changed with increasing or decreasing water temperature. While when the temperature was in a moderate range, an increase or decrease of water temperature would lead to a rapid increase or decrease in .

Strategies for Water Security and Aquatic Ecosystem Restoration in the Yangtze River Economic Belt

Hu Chunhong, Zhang Shuanghu

Strategic Study of CAE 2022, Volume 24, Issue 1,   Pages 166-175 doi: 10.15302/J-SSCAE-2022.01.018

Abstract:

Working together on protection instead of excessive development is the key strategy for promoting the high-quality development of the Yangtze River Economic Belt. It is necessary to tackle principal contradictions with targeted measures in the process of Yangtze River protection. In this paper, we analyze the major issues regarding water security and aquatic ecosystem protection in the Yangtze River Economic Belt, including the severe flood control safety situation, the serious shrinkage of suitable habitats for aquatic animals and biodiversity reduction, and the dysfunctional relationship between the Yangtze River and its connected lakes. Additional, we propose several targeted measures and strategies. The measures for improving the flood control capability are to accelerate the construction of safety projects in critical flood storage and detention areas and revise the Yangtze River Basin Flood Control Planning. The strategies for restoring the damaged aquatic ecosystem are to construct substitute habitats in the tributaries in the upper reaches of the Yangtze River, restore the connection between the Yangtze River and some former connected lakes in the middle and lower reaches, and expand the ecological operation of reservoirs. The strategies for regulating the river–lake relationship are to improve the four water systems in the north of the Dongting Lake and build floodgates at the outlet of the Poyang Lake.
