What are some effective techniques for sensor fusion in mobile robots?

Asked on Jan 10, 2026

Answer

Sensor fusion in mobile robots involves combining data from multiple sensors to improve perception and decision-making. Effective techniques include Kalman filtering, particle filtering, and complementary filtering, each suited for different types of data and noise characteristics.

Example Concept: Kalman filtering is a popular technique for sensor fusion in robotics, particularly for linear systems with Gaussian noise. It provides an optimal estimate of the system's state by predicting the next state and updating it with new measurements. This method is widely used in mobile robots for tasks such as localization and tracking, where it helps to smooth out sensor noise and improve accuracy.

Additional Comment:

Kalman filters are ideal for systems with known dynamics and Gaussian noise.
Particle filters are more flexible and can handle non-linear systems and non-Gaussian noise.
Complementary filters are simpler and often used for fusing accelerometer and gyroscope data.
Choosing the right technique depends on the specific application and sensor characteristics.
