Research Contents

I’m interested in the bio-sonar strategies employed by bats. They accomplish the 3D acoustic navigation in real time by using simple designed sonar system consist of 1 transmitter and 2 receivers. My purpose is to understand the active sensing ingenuity of the bats and apply the bio-inspired navigation system to the autonomous flying drones.

Attractive Factors of My Research

“Done is betterthan perfect” This is a quote from from Zuckerberg.In classroom lecture, teacher always give you the solvable questions and solving method. But in research, you have to make up ploblem and solve it by yourself. I think these are the most atractive points of research activity. In these tasks, Zuckerberg’s words will help you.
