“…Referring to previous research results [ 30 , 31 ], the coupling coordination level is divided into 10 categories and the coordination degree is divided into 3 categories. The coupling coordination of elderly care service resource supply and demand is poor coordination when the coupling degree is lower than 0.4.…”

The current situation and future development of the supply and demand coupling coordination of elderly care service resources reflect the level of elderly care service resource allocation. Whether factors affecting its development can be found is the key to promote the accurate allocation of elderly care service. Based on the coupling coordination model, the supply and demand of elderly care service resources, the development circumstance and the spatio-temporal evolution of supply and demand coupling coordination are analyzed in this paper by using the data of the elderly care service resources in 31 regions and autonomous regions in China from 2010 to 2019. The result shows that there are regional differences in the development of supply and demand coupling coordination of elderly care service resources. The degree of supply and demand coupling coordination of elderly care service resources in the western and northern regions is lower than that in the eastern and southern regions. Although the level in most areas of supply and demand coupling coordination of elderly care service resources will improve in the future, there is still a gap from good coordination. In order to strengthen the supply of elderly care service resources, and promote the upgrade of the supply and demand of elderly care service resources, the government should start from the demand of the elderly to increase investment in infrastructure construction, investment in elderly care services resources, talent training and other aspects.

“…The dynamics solver solves the robot and PTL subsystems, respectively, by the contact estimator, which fully considers the pressure and friction between the robot and PTL. [16][17][18] The robot made by the Special Robot Research Institute of Wuhan University [19][20][21] is modeled by screw theory, [22][23][24] while the PTL including LGJ-400/35 four-split conductor is modeled using absolute node coordinate formulation (ANCF). [25][26][27] The coupling dynamical equation (1) can systematically cover the influence of the interaction between the robot and PTL…”

This article presents a novel method—Dynamic Environment Rapid Search Tree—for power transmission line maintenance robot, which is based on the learned field function of reachability and the genetic best-first policy. Dynamic Environment Rapid Search Tree uses a priori information to optimize the node selection strategy in the rigid–flexible coupling environment with slight perturbation and generates the joint path in the configuration space. While the search tree rapidly extends toward the goal configuration, it effectively avoids the obstacles and greatly reduces the expansion of the irrelevant region. Finally, the joint trajectory considering the dynamic constraints and cost function is given, which provides the reference positions and torques for the robot controller. Traditional planning algorithms are compared with our proposed method under two different operation modes, and the planner is demonstrated on the robot under real settings. The experiment results verify the feasibility and adaptiveness of the proposed algorithm and planner, even in slightly and continuously varying environment.
