Desert ants use the polarization of skylight and a combination of stride and ventral optic flow
integration processes to track the nest and food positions when traveling, achieving …

Many insects navigate by integrating the distances and directions travelled on an outward
path, allowing direct return to the starting point. Fundamental to the reliability of this process …

Many insects such as desert ants, crickets, locusts, dung beetles, bees and monarch
butterflies have been found to extract their navigation cues from the regular pattern of the …

In this paper, we design a novel robust control method to reduce the trajectory tracking
errors of the SCARA robot with uncertainties including parameters such as uncertainty of the …

A bio-inspired polarization sensor with lenses for navigation was evaluated in this study.
Two new calibration methods are introduced, referred to as “central-symmetry …

This article studies the measurement error model and calibration method of the bio-inspired
polarization imaging orientation sensor (BPIOS), which has important engineering …

Over the last five decades, legged robots, and especially six-legged walking robots, have
aroused great interest among the robotic community. Legged robots provide a higher level …

Autonomous or unmanned ground vehicles can take advantage of camera-based navigation
systems. These navigation systems mainly rely on standard radiometric cameras. The use of …

The bionic polarimetric imaging navigation sensor (BPINS) is a navigation sensor that
provides absolute heading, and it is of practical engineering significance to model the …

In this letter, we develop a tightly coupled polarization-visual-inertial localization system that
utilizes naturally-attributed polarized skylight to provide a global heading. We introduce a …
