Insect-Inspired Robotic Homing

Many animals, including insects, successfully engage in visual homing. We describe a system that allows a mobile robot to home. Specifically, we propose a simple, yet robust, homing scheme that only relies upon the observation of the bearings of visible landmarks. However, this can easily be extended to include other visual cues. The homing algorithm allows a mobile robot to home incrementally by moving in such a way as to gradually reduce the discrepancy between the current view and the view obtained from the home position. Both simulation and mobile robot experi ments are used to demonstrate the feasibility of the approach.
