This paper investigates the on-orbit maintenance task planning of large-scale space solar power station. The research is of great significance for the normal operation of large-scale space equipment. Space robots are very maneuverable, which makes space maintenance possible. A new task planning algorithm is proposed for the on-orbit maintenance of space robots. Firstly, based on the discretization method, the modified clustering method is used to cluster the maintenance area of large-scale space solar power stations. Secondly, the hierarchical structure principle is used to assign tasks to the space robot, the inner layer plans the shortest path within the cluster set, and the outer layer plans the optimal path between the cluster sets. Finally, based on the optimal path of the outer layer of the maintenance task, a hybrid optimization algorithm based on tabu algorithm and modified ant colony algorithm is proposed. The algorithm can meet the space machine task allocation requirements and analyze the maintenance path under certain energy conditions. The simulation results show that the proposed algorithm can effectively solve the optimal problem of space robot mission planning under resource constraints. INDEX TERMS Space robot, task clustering, hybrid optimization algorithm, task planning.

“…151-157). The Earth's orbit, as a potential source of solar energy, is the goal for obtaining and exploiting this type of energy from solar radiation (Li et al, 2017). The intensity of solar radiation near the equator on a sunny day at noon with a cloud-free sky is about 1,000 watts per m2, while the Earth's orbit is a constant value of 1,368 watts -27 % more.…”

The work focuses on the controversy about technological progress and unlimited access to all kinds of energy acquisition, storage and distribution. It suggests a formula for energy acquisition and usage which embraces issues of peace and war, social conflicts, and stability determined by access to energy conditioned by the state of the climate of our planet. The question is how will an interdisciplinary combination of progress and future implementation of technologies influence energy security of states and social entities, their natural environment, up to 2030 and beyond? The methods used in the work rely on a non-linear approach to disruptive technologies combined with empirical verifiability of scientific progress in the field of energy acquisition and use. They are reinforced with drivers taken from development scenarios gained through technological development in quantum mechanics, molecular biology, and computational techniques. The result is a conceptual approach to energy acquisition and distribution for states, their communities and individuals regardless of whether the technologies are "civil" or "military" in their essence. The recalled disruptive technologies shape factors of social development and create conditions for human existence and the natural environment that influence the security of states and social entities. The development of automation and robotics, digital transformation, biotechnologies and cognitive science creates new energy security for states, social entities and the natural environment. Technologies for the generation, processing and distribution of energy create an almost unlimited perspective of reconfiguration of existing forms of life and their safety.

“…On the other hand, concentrated solar energy can be also harvested by way of technologies installed in the Earth orbit. Those are, for example, space solar power satellite systems (SSPS) that collect and convert solar irradiation to electric power in space and transmit the electric power to earth wirelessly [64]. Since the power beams can be directed from the orbit to the regions where the sun is not shining, particularly SSPS-based systems would potentially improve the access to instantaneous solar power, thus being worth considering with respect to the 'ubiquitous energy' concept.…”

The continuous and rapid development of energy technology challenges the scientific community to ponder the long-term energy evolution from the perspective of sustainable energy transition.We state that one of the key challenges for the new (post-fossil) energy era is to guarantee to all energy users an access to adequate resources of energy everywhere and at any moment of time.To crystallize the key ideas of such a pervasive energy supply chain into a single concept, we introduce the concept 'ubiquitous energy'. The main contribution of our paper is to create a discussion framework for the concept and to identify the most relevant technology pathways for the realization of 'ubiquitous energy'. Hence, we first present the background of the concept and discuss matters concerning the 'quality of energy to be present everywhere'. Secondly, we review the latest innovations in energy technology with respect to the energy supply chain and summarize technology pathways to 'ubiquitous energy'. To that end, we describe a systematic framework to classify energy technologies under energy generation, storage, transmission and distribution. We conclude that 'ubiquitous energy' covers various solutions in both scope and degree of integration, but the most prominent trend of development is the use of distributed and shared resources and local energy supply chains. Here, the research should focus on integrated and mobile energy conversion and storage options and wireless power transmission.
