How does sensor fusion improve the accuracy of autonomous robot navigation?

Asked on Dec 04, 2025

Answer

Sensor fusion enhances the accuracy of autonomous robot navigation by integrating data from multiple sensors to create a more reliable and comprehensive understanding of the environment. This process mitigates the limitations of individual sensors, such as noise or blind spots, and improves the robot's ability to make informed decisions in dynamic environments.

Example Concept: Sensor fusion combines data from various sensors like LiDAR, cameras, IMUs, and GPS to improve localization and mapping accuracy. By using algorithms such as Kalman filters or particle filters, the robot can merge these data streams to estimate its position and orientation more precisely, resulting in better path planning and obstacle avoidance.

Additional Comment:

LiDAR provides precise distance measurements but may struggle with reflective surfaces.
Cameras offer rich visual information but can be affected by lighting conditions.
IMUs help track motion dynamics but can drift over time without correction.
Combining these sensors compensates for individual weaknesses, enhancing overall navigation robustness.
