Stern Technic GmbH — Deep Dive, March 2026** --- Anyone familiar with BOB knows: This project is different. BOB is not an ordinary drill. BOB is an autonomous displacement drill—51 millimeters in diameter, 704 millimeters long, equipped with counter-rotating helixes, an IMU, two Faulhaber motors, and the goal of working its way through the subsurface independently. Without trenching, without excavators, without tearing up roads. And right now, while new mechanical parts are i

The success at bauma 2025 clearly demonstrated one thing: the industry is desperately seeking solutions to end the "blind flight" underground and make pipeline construction more efficient and safer. At Stern Technic, we have taken up this demand. Our vision of a networked, intelligent construction site is now becoming a reality. Holistic process reliability instead of isolated hardware Conventional trenchless pipeline construction methods often pose incalculable risks to ex

Between technological endurance tests, economic foresight, and a vision for the trenchless construction of tomorrow. For Stern Technic, 2025 was not a year of vague concepts, but a year of reality. In a market environment increasingly demanding resilient solutions, it became clear which technological approaches truly hold weight. For Stern Technic, the year was defined by validation: the development of cyber-physical systems was consistently pushed forward to meet the challen
