“…Future opportunities in on-site automation and robotics arise through the promotion of smart buildings and cities as cyber-physical systems, intelligent life-term monitoring of infrastructure assets and new analytics maintenance insights to ensure sustainable decisions [61]. Nagarajan, Li et al [68] investigate robotic maintenance of critical infrastructure systems like transmission lines to minimize likelihood and severity of power outages which otherwise come with severe financial and societal consequences. Results of their research also allowed for a 95% reduction in energy consumption and carbon dioxide emissions by replacing helicopters with suspended robots for inspecting transmission lines.…”

“…On the other hand, on-site robotics and automation still face limitations, mostly related to implementation costs, inflexibility and technological immaturity [68]. This includes measurement accuracy, sensor miniaturization, cost barriers, support of wireless communication, sensor smartness, long-term powering and durability issues [62].…”

This article identifies how project life cycle characteristics and automation and robotic technologies influence the sustainability of public-private partnership (PPP) infrastructure projects. The result of the article is a model of how public and private collaborations can leverage technology and project organization to make infrastructure more sustainable. Based on a comprehensive literature review, the model subdivides sustainability into engineering, project management, environmental, social, and economic dimensions. Engineering sustainability concerns the applicability of technologies to infrastructure PPP sustainability. The project management sustainability is decisive for ultimately creating environmental, social and economic sustainability within and beyond infrastructure PPP projects. The model identifies that the procurement phase is of particular importance for sustainable infrastructure PPPs. Successful sustainable infrastructure procurement likely includes such factors as increased transparency, participation, and stable, capable project alliances with a shared vision and clear goals. The model also identifies that, throughout the whole project life cycle, actions in the form of collaboration, experimentation and platformization promote sustainability. The findings in this article add to the understanding of how transformation toward increased sustainability can be achieved by individual organizations, their network, and ecosystems of public, private and civic actors.

“…Robotic applications for the maintenance of electrical live power lines began in the 1980s [2][3]. The current research directions are power transmission line inspection [4][5], teleoperation [6] and the development of mechanism design [7][8]. Robot technology plays an important role in solving this problem, but a robot cannot exactly mimic a person when manipulating the parallel groove clamp.…”

Exact location calculation between each part of a parallel groove clamp when connecting a power line with a jumper is addressed in this paper. The relative location between a concave clamp and convex power line cannot be measured directly in live-line manipulation. We propose a concave arc surface collision detection method embedded in motion simulation. The relative location between irregular concave parts in the manipulation process can be obtained. The method is found to be computationally less expensive than convex partitioning collision detection techniques. This research provides a foundation for further study on robot hand manipulation with irregular assembly.

“…Today, many countries have to urgently address the issue of the timely detection and elimination of defects in transmission lines [14][15][16][17]. What makes it highly relevant to design appropriate 'preemptive' solutions is their strong economic effect that shows in lower expenditures on the elimination of failures, compensation of power losses and operating costs [13,[17][18][19][20].…”

“…This is particularly relevant to vast countries and countries with complex terrain (Russia, Canada, Italy and others). An alternative is to use piloted aircraft or unmanned robots to monitor such facilities [20][21][22]. This study analyzes the capabilities of diagnostic and maintenance robots for overhead transmission lines, including the Russian-made Cablewalker technology that is now in trial operation.…”

The digitization of power grids envisages a transition to new models of fault diagnosis, repair and maintenance of electric power grid equipment. The most promising tools for implementing advanced production asset management strategies are integrated technologies that are based on robotic diagnostic platforms, various hardware-software instruments and smart data analysis systems. The article analyzes other countries' experience of developing robotic methods of fault diagnosis and maintenance of overhead power transmission lines, which present a major challenge in terms of monitoring, failure prediction and localized repairs. The Cablewalker robotic system was used as an example for identifying the advantages of integrated diagnostic hardware systems as opposed to traditional methods of power grid equipment maintenance and overhaul. Recommendations are given for adopting the technology in grid companies. During trials of the technology on a 2.34-km section of a power transmission line 112 defects were detected versus three that were identified by means of 'manual' inspection. A digital twin of the transmission line was created to manage its technical condition with regard to various risks.
