An Automatic Navigation System Based On A Rat-mounted Camera And A Bird’s Eye Camera

Animal robot is connected to a machine system via a brain-computer interface. It has a great advantage over traditional robot in the flexibility of movement, automatic energy supply, and environmental adaptability. There are strong prospects for the application of national defense, environmental investigation and disaster rescue. A rat robot is a type of animal robot. Electrical stimuli can be generated by the machine system and delivered to the rat’s brain to control its behavior. However, most existing rat robots require that a human observes the environmental layout to guide navigation, which limits the applications of rat robots.This work designs and implements an automatic navigation system based on a bird’s eye camera and a rat-mounted camera. This work also designs a lot of experiments to evaluate the system. The main contribution of this paper is,(1) This paper designs the structure of the automatic navigation system. What’s more, this paper designs the control strategy of the whole system.(2) This paper designs and implements the compute model and control strategy of the bird’s eye camera and the rat-mounted camera respectively. Inspired by the fact that humans usually give a series of stimuli to a rat robot, we develop a closed-loop model that issues a stimulus sequence automatically according to the state of the rat and the objects in front of it until the rat completes the motion successfully.(3) This paper also shows the flow of the system in experiments. The object detection methods and the closed-loop stimulation model are evaluated in experiments. Through the analysis of experimental results, the efficiency of the stimulation model are verified.
