In this work, adaptive hybrid navigation methods for tethered robots in the real-world are investigated for navigation in changing environments. Traditional navigation systems rely on simulations, and therefore overlook complexity and unpredictability of the real application. We present a new way of overcoming these restrictions through a combination of state of the art sensor fusion techniques for reducing sensor noise and variability with soft computing techniques such as fuzzy logic, evolutionary algorithms and neural networks. Next, we propose real time adaptive path planning methods, addressing the problem of moving obstacles and varying tether configuration using optimal control for navigation efficiency. Combination of bug algorithms with soft computing frameworks improves resilience and responsiveness in uncertain contexts. We also suggest sophisticated retrieval methods for efficient tether management after navigation. Through substantial simulations and real world trials, we demonstrate the effectiveness of the proposed strategy, which would significantly boost navigation reliability and system adaptability in complex environments. Results show that our method provides improved tethered robot performance, which guarantees reliable operation in dynamic environments.
