Abstract
Purpose
Several studies have aimed to develop robotic systems which move in transmission lines. Until this moment, all of them have a high weight and cost associated with the equipment and reduced battery autonomy time. In this context, this paper aims to propose the POLIBOT (POwer Lines Inspection roBOT) with low cost and weight, enabling the movement over the lines and an easier installation and remove.
Design/methodology/approach
The designed robot uses the Profiles Manufacturing Methodology (PMM). The construction of the robot mechanical structure uses modularized aluminum parts built through square profiles. Thus, it’s possible a drastic reduction in production time as well as cost reduction and weight when comparing this method with other manufacturing processes like foundry, for example. For hardware and software systems, the use of free and open source software causes a significant reduction in cost and project execution time. The benefits of using open source systems are immeasurable, both from academic and industrial applications.
Findings
The POLIBOT platform is one solution to the problem of inspection in power lines. With this robot, more lines are maintained with lower time. In its constructive aspect, the robotic mechanism is designed using principles of bioengineering. The use of this principle was successful, considering that obstacle transposition is performed with stability and low energy consumption.
Research limitations/implications
The suggestion for future researches is to replace the battery for solar energy and construction in polymeric material to avoid high magnetic fields.
Practical implications
The commercial application is evident because manual inspections are inefficient, very expensive and dangerous. Thus, it is growing the number of researches that develop mechatronics systems for this kind of inspection.
Social implications
The impact is the reduction of accidents because the present procedure requires precision of movements, where the pilot and electrical technician are close to high electrical and magnetic fields. In addition, for some tasks, the worker has to walk on the line to reach some important points. Thus, those tasks involve high risk of death.
Originality/value
The PMM methodology represents an innovation to the state of the art because others robotic mechanisms proposed for inspection tasks present total structure mass between 50 and 100 kg and POLIBOT has only 9 kg. Other fact is its price for implementation as this robot used the robot operating system (ROS) framework, what dispense the use of licenses. Other important features are that the robot performs the tasks autonomously, which reduces errors introduced by the operator and its low manufacturing cost as compared with other projects.

This paper aims to investigate the role of resource orchestration in turnaround attempts following the organizational decline in the context of an emerging economy.
Abstract
Purpose
This paper aims to investigate the role of resource orchestration in turnaround attempts following the organizational decline in the context of an emerging economy.
Design/methodology/approach
Multicase study of three Brazilian textile firms, following their trajectory from 1997 to 2009. We did a “historical reconstruction using the methodology” proposed by Mintzberg and McHugh (1985) to guide our data collection and analysis procedures. The methodology is geared towards the study of the evolution of organizations over a past period, wherein the researcher reconstructs the events after they have occurred, having developed them from documentary analysis and oral history.
Findings
The results indicate that resource orchestration is a critical capability for ensuring the coordinated implementation of operational and strategic actions in a turnaround. Moreover, in a context involving severe environmental jolts, the conservation of organizational slack appears to influence the effectiveness of resource orchestration and explains the different outcomes the firms in this study achieved in their turnaround attempts.
Research limitations/implications
This paper may be useful to practitioners involved in turnarounds, helping them evaluate the consequences of decisions involving the acquisition, reconfiguration, bundling and divestment of firm resources.
Practical implications
Besides contributing to the advancement of theory-informed research on decline and turnaround, this paper may be useful to practitioners involved in turnarounds, when they consider the consequences of decisions involving firm resources.
Originality/value
This paper helps advance theory-informed research on decline and turnaround in developing economies, helping address a gap in the extant literature, primarily focused on firms in developed countries.
Objetivo
Investigar, en el contexto de una economía emergente, el papel de la orquestación de recursos en los intentos de recuperación después del declive organizacional`.
Metodologia
Estudio multicaso de tres empresas textiles brasileñas siguiendo su trayectoria desde 1997 hasta 2009. Hicimos una “reconstrucción histórica utilizando la metodología” propuesta por Mintzberg y McHugh (1985) para guiar nuestra recopilación de datos y procedimientos de análisis. La metodología está orientada hacia el estudio de la evolución de organizaciones en un período pasado, en el que el investigador reconstruye los eventos después de que han ocurrido, habiéndolos desarrollado a partir del análisis documental y la historia oral.
Resultados
Nuestros resultados indican que la orquestación de recursos es una capacidad crítica para garantizar la implementación coordinada de acciones operativas y estratégicas en un processo de recuperación. Adicionalmente, en un contexto que implica impactos ambientales significativos, mantener la holgura organizacional parece influir sobre la eficacia de la orquestación de recursos y explica la diferencia de los resultados que las empresas encuestadas alcanzaron en sus tentativas de recuperación.
Implicaciones prácticas
Este artículo puede ser útil para los profesionales implicados en procesos de recuperación, ayudándoles a evaluar las consecuencias de las decisiones que implican la adquisición, reconfiguración, agrupación y desecho de recursos de la empresa.
Originalidad/valor
Este estudio contribuye al avance de la investigación de base teórica sobre declive y recuperación en economías en desarrollo, ayudando a eliminar una laguna en la literatura existente, la cual se a centrado principalmente en empresas en países desarrollados.

Resultados
Nossos resultados indicam que a orquestração de recursos é uma capacidade crítica para garantir a implementação coordenada de ações operacionais e estratégicas num turnaround. Adicionalmente, num contexto envolvendo choques ambientais significativos, a preservação da folga organizacional parece influenciar a eficácia da orquestração de recursos e explicar a diferença dos resultados que as empresas pesquisadas alcançaram nas suas tentativas de turnaround.
Implicações práticas
Este artigo pode ser útil para profissionais envolvidos em turnarounds, ajudando-os a avaliar as consequências de decisões envolvendo a aquisição, reconfiguração, agrupamento e descarte de recursos da empresa.
Originalidade/valor
Este estudo contribui para o avanço da pesquisa de base teórica sobre declínio e turnaround em economias em desenvolvimento, ajudando a eliminar uma lacuna na literatura existente, focada principalmente em empresas em países desenvolvidos.
