The Prometheus 2.0 rover represents Axist’s solution for offshore measurements and constitutes a significant step forward in the development of mobile robotic platforms dedicated to inspection and metrological applications. Compared to its predecessor, the system introduces a more advanced hardware/software architecture able to improve motion control, measurement processes, and operator feedback. A key case study is the monitoring of flange ovalization inside monopiles, a critical task in offshore wind energy structures, where traditional measurement methods prove impractical. The rover’s architecture is based on distributed microcontrollers, Ethernet communication, and a dedicated workstation for supervision and data storage. Within this configuration, particular attention was given not only to the design of the subsystems, such as the azimuth and elevation servos coupled with the Ovality Box and the power management unit, but also to the complete study, design, and validation of all hardware connections and cabling, carried out during the development process to guarantee electrical robustness, signal integrity, and operational safety.
