The research aims to develop a navigation framework that ensures vehicle safety and efficiency on uneven terrain while considering various constraints.
Created a 2D global terrain traversability cost map using terrain slope, flatness, elevation variation, and sparsity.
Developed a three-phase path planning algorithm integrating A*, guided RRT, and a new KT-PRM local re-planning algorithm.
Applied Nonlinear Model Predictive Control (NMPC) for accurate path tracking.
The three-phase algorithm significantly improved path safety and smoothness compared to existing methods.
Generated shorter paths that reduce detours while maintaining kinematic feasibility and minimizing rollover risk.
Demonstrated comprehensive performance in both simulated and real-world environments.
