The inspection and maintenance of transmission systems are necessary for their proper functioning. In this way, among the line’s critical points are the insulator chains, which are responsible for providing insulation between conductors and structures. The accumulation of pollutants on the insulator surface can cause failures in the power system, leading to power supply interruptions. Currently, the cleaning of insulator chains is performed manually by operators who climb towers and use cloths, high-pressure washers, or even helicopters. The use of robots and drones is also under study, presenting challenges to be overcome. This paper presents the development of a drone–robot for cleaning insulator chains. The drone–robot was designed to identify insulators by camera and perform cleaning through a robotic module. This module is attached to the drone and carries a battery-powered portable washer, a reservoir for demineralized water, a depth camera, and an electronic control system. This paper includes a literature review on the state of the art related to strategies used for cleaning insulator chains. Based on this review, the justification for the construction of the proposed system is presented. The methodology used in the development of the drone–robot is then described. The system was validated in a controlled environment and in field experimental tests, with the ensuing discussions and conclusions formulated, along with suggestions for future work.

High-voltage power line insulators are crucial for safe and efficient electricity transmission. However, real-world image limitations, particularly regarding dirty insulator strings, delay the development of robust algorithms for insulator inspection. This dataset addresses this challenge by creating a novel synthetic high-voltage power line insulator image database.

Este artigo tem por objetivo apresentar o Plano de Comunicação, que visa a apoiar a transferência de conhecimento e a criação de uma visão compartilhada entre os integrantes de um Projeto de Pesquisa e Desenvolvimento. O referencial teórico baseia-se nas áreas da Gestão de Projetos, Gestão do Conhecimento e Comunicação Organizacional. Metodologicamente caracteriza-se como uma pesquisa experimental, intraprojeto e interorganizacional. Os resultados ainda não são efetivos em razão do pouco tempo de implantação do projeto; contudo, com base nas ações já implantadas, pode-se inferir que a Comunicação é um elemento importante na transferência do conhecimento e na criação de uma visão compartilhada.
