By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News – Investigators publish new report on ro botics. According to news reporting originating from Parana, Brazil, by NewsRx c orrespondents, research stated, “Some robots are designed to be lightweight and flexible, enabling them to access small and challenging paths in various applica tions.” The news editors obtained a quote from the research from Federal University: “Th ese features enable robots to collaborate with humans in performing specific pro duction tasks. However,the movement of the flexible manipulator can become self- excited when handling a cutting tool on a workpiece, which can lead to a control problem. This article presents a control solution for lightweight robotic manip ulators with rotating tools, such as polishing and milling, using smart actuator s. The control discretization method is also introduced to facilitate integratio n into digital controllers. The paper starts by describing the governing equatio ns of the non-ideal flexible manipulator for polishing and milling and analysing its dynamic behavior. Subsequently, models for the controllers of the DC motor- only actuators and the hybrid (shape memory alloy and DC motors) actuators were formulated using shape memory alloy and a suboptimal control scheme known as the discrete state-dependent Riccati equation.”
