Overcoming the sim-to-real gap: Algorithms that excel in simulation struggled in reality due to localisation errors Pure Pursuit algorithm was more robust: the algorithm transitioned smoothly to the real vehicle, while MPC required refinement. MPCC, though fastest in simulation, failed in practice. Fixes Improved Real Performance: Kalman filtering, delay compensation, and adaptive steering stabilised MPC, but MPCC remained limited by onboard computational constraints.
