The goal of our research is to elucidate neural basis of adaptive behaviors
in animals. In this seminar, I will talk about the use of an insect-driven hybrid robot for
biological and robotic studies, and will also introduce about related projects in our labo-
ratory (conducted by prof. Ryohei Kanzaki).
Tracking an odor plume and localizing the odor source is a challenging task for
autonomous robots. Animals including small insects rely on olfaction, and finding an
odor source is an essential task to survive. Therefore, biomimetics of their behavioral
mechanisms is a plausible approach for the development of robotic odor source localiza-
tion. However, it has been difficult to estimate the potential performance of such
biomimetic robots because the biological analyses have not yet been completed. We
developed an insect-driven mobile robot to solve this problem. Since the robot is driven
by a real insect, we can regard it as a robot implemented with a complete insect sensory-
motor system. We demonstrated that the robot driven by a male silkmoth (Bombyx mori)
satisfied the two requirements of the biomimetic robots: 1) capability to localize an odor
source as the model insects do, and 2) capability to overcome unpredictable perturba-
tions during locomotion. In addition to the biomimetic perspective, we employed this
robot as an experimental tool for behavioral experiments. We analyzed behaviors of the
robot (i.e. behavior of an onboard moth) in response to perturbations of sensory or mo-
tor properties of the robot, and found the precise directional control and flexible strate-
gies to effectively localize an odor source in silkmoths. As a future direction, we think
that the hybrid robots enable us to directly compare a model and a real insect on the
same robotic platform, which will facilitate the understanding of biological systems and
its application to artificial systems.
