Abstract
An evaluation method is described that will enable researchers to study fight control characteristics of robo-pigeons in fully open space. It is not limited by the experimental environment and overcomes environmental interference with flight control in small experimental spaces using a compact system. The system consists of two components: a global positioning system (GPS)-based stimulator with dimensions of 38 mm × 26 mm × 8 mm and a weight of 18 g that can easily be carried by a pigeon as a backpack and a PC-based program developed in Virtual C++. The GPS-based stimulator generates variable stimulation and automatically records the GPS data and stimulus parameters. The PC-based program analyzes the recorded data and displays the flight trajectory of the tested robo-pigeon on a digital map. This method enables quick and clear evaluation of the flight control characteristics of a robo-pigeon in open space based on its visual trajectory, as well as further optimization of the microelectric stimulation parameters to improve the design of robo-pigeons. The functional effectiveness of the method was investigated and verified by performing flight control experiments using a robo-pigeon in open space.
Highlights
Some animals have amazing senses of smell that enable them to detect narcotics, explosives, and pipeline leaks (Britt et al, 2008)
The global positioning system (GPS)-based microstimulator was powered by a rechargeable 3.7 V, 240 mAh polymer battery attached to the back side of the motherboard and electrically connected to the motherboard when used by turning on the microswitch
The battery of the system lasts about 2.3 h, which is enough for conducting a complete test of robo-pigeon, compared with an average of slightly more than 1 h needed for each test
Summary
Some animals have amazing senses of smell that enable them to detect narcotics, explosives, and pipeline leaks (Britt et al, 2008). Engineers have not developed any device with odor detection capabilities comparable to those of canines. Some animals can traverse a variety of terrain types more efficiently than electromechanical robots or humans (Grinke et al, 2015); for instance, engineers have not developed a micro air vehicle with flight abilities comparable to those of pigeons. Animals could be employed to conduct search and rescue missions more efficiently than electromechanical robots if they could be controlled. Increasing interest is developing in the prospect of controlling animals and utilizing them as new kinds of robots. Special kinds of bionic robots called bio-robots have been developed based on brain–computer interfaces (BCIs), which involve direct communication between the brain and an external device. The MFB was stimulated to generate intense excitement as a virtual reward, while the left
