Drone-robot to install aerial marker balls for power lines

To enhance the safety of our airspace, it is essential to implement devices along overhead power lines that effectively reduce the likelihood of collisions involving aircraft, helicopters, balloons, and other airborne objects. Aerial marker balls, which adhere to technical standards concerning their geometry and characteristics, are commonly used for aerial signaling on power transmission systems. Currently, aerial marker balls are installed by technicians either via helicopter or by utilizing ropes to perform the task manually. This process results in significant expenses and exposes the technicians to considerable risk. While robotic methods have been explored, they often present impractical challenges. Despite the advancements in various techniques, difficulties persist in this field. The primary objective of this paper is to design and develop a robotic module that can be attached to a drone, enabling the semi-automated installation of aerial marker balls. The robot model was designed using Computer Aided Design and Computer Aided Engineering software’s, with a subsequent description of the control system. After constructing the drone-robot, it was tested in a simulated environment, proving to be both efficient and cost-effective. This innovative approach improves not only the cost-effectiveness of aerial marker ball installation but also the safety of technicians involved in the process.
