About

Ricardo Artigas Langer is a robotics researcher whose work centers on autonomous navigation and specialized inspection systems for challenging environments. His most influential contribution is the **K-Bug algorithm**, introduced in his 2007 paper (32 citations), which offers a novel approach to mobile robot path planning within the Bug family of methods. By leveraging local information to improve performance, the K-Bug algorithm provides a versatile framework that can either enhance existing planners or serve as a standalone solution for obstacle avoidance and goal-reaching tasks. This work has become a reference point for researchers seeking efficient, sensor-based navigation strategies. Langer also addresses real-world industrial needs with his 2010 design of a **robot for offshore pipeline inspection** (7 citations). This robot targets the critical task of detecting damage to the external sheath of pipeline risers—the vital connection between seabed pipes and floating production platforms. By tackling the harsh conditions of offshore environments, Langer demonstrates a commitment to applying robotics to high-stakes infrastructure maintenance. His research bridges theoretical advances in motion planning with practical, deployable solutions, making him a notable figure in field robotics and autonomous systems.
