コウモリのハイブリッド超音波センシング術を模倣した自律走行ロボットによる2台走行実験

Echolocating bats conduct ultrasonic sensing using a single transmitter (nose or mouth) and two receivers (both ears). They can safely fly even in complicated environments, thus, the echolocation of bats is thought to be excellent model from the viewpoint of acoustic sensing. To implement ultrasonic sensing operation observed in bats on a simple autonomous mobile robot, we can evaluate bat’s biosonar system which has not been well understood. Previous studies reported that while two individuals fly together, it is reported that one bat in pair occasionally cease emission of ultrasound pulses. In this study, we conducted the evaluation focusing on the obstacle route completion rate of paired driving by using two robots that were controlled based only on sensing information of ultrasound. We investigated how the completion rate of vehicles changes by imitating passive sensing behavior of bats during paired flight.
