About
Alexandre Queiróz Bracarense is a leading figure in the intersection of robotics and welding engineering, with a career dedicated to automating dangerous industrial tasks. His most impactful work involves the development of mobile manipulators for the electric power sector, specifically a semi-autonomous robot for installing and removing aircraft warning spheres on live power transmission lines—a task that traditionally puts human workers at extreme risk. This flagship project, detailed in his most-cited paper (41 citations), employs hybrid systems for autonomous and tele-operated control. Bracarense has also made significant contributions to precision welding automation, including a chain-driven robot for orbital pipe welding and the use of artificial neural networks to predict weld parameters in austenitic stainless steel (25 citations). His research extends into specialized domains like underwater welding, where he has developed novel methods for flux-cored wire formulation and diffusible hydrogen measurement. By founding the Robotics, Welding and Simulation Laboratory, Bracarense has established a hub for innovation that directly addresses safety and efficiency in critical infrastructure maintenance.
