Fei GAO’s HomePage

My name is Fei Gao (高飞) and I’m from China. The meaning of my name in Chinese is: flying high in the sky : )

I’m a Ph.D. candidate working on Aerial Robot in the UAV Group, RI, HKUST. Before I came to HKUST, I got my Bachelor degree in Control Science & Engineering from Zhejiang University. My research area includes motion planning, control, applied convex optimization, and swarm. I’m also interested in robotics exploration and autonomous aerial videography. You can check the following publication and video lists for details about each project.

I like robots, and I like making a system autonomous. Also, I enjoy doing research. I want to do more research before I leave here so probably I will not graduate very soon, at least not early than the year 2020. So HRs can ignore me. If you have some ideas to share with me or have some questions about my works, you can find me at: fgaoaa@connect.ust.hk

Source Code

GTOP: Gradient-Based Trajectory Optimizer by Fei Gao and Boyu Zhou.

A ROS-package for piecewise polynomial trajectory optimization written in C++. Details can be found in the related paper Gradient-Based Online Safe Trajectory Generation for Quadrotor Flight in Complex Environments.

Btraj: Bezier-Curve-Based Trajectory Generator by Fei Gao

Btraj is an online UAV planning framework used to generate safe, dynamically feasible trajectories in previous unknown environments. It can be divided as a front-end path finding module and a back-end trajectory optimization module. In the front-end, we provide two alternates: Fast Marching*(FM*) on a velocity field and A* on a pure grid map. A flight corridor consists of cubes are generated based on the path. In the back-end, we utilize properties of Bezier curve to confine the piecewise Bezier curves entirely within the corridor and dynamical limits. Details can be found in the related paper Online Safe Trajectory Generation For Quadrotors Using Fast Marching Method and Bernstein Basis Polynomial.

More source code packages for other paper will be released soon.
