Relative Localization and Formation Tracking

2017

In this project, three UAVs autonomously estimate and maintain their relative formation using their relative distances and individual velocity estimates. Ultra-wide Band (UWB) nodes are used to obtain distance and PX4Flow module for visual odometry.

Autonomous navigation flight with Laser SLAM

2016

A UAV, equipped with a 270-degree laser scanner, accurately determines its position and surrounding environment to autonomously navigate to its goal while safely avoiding obstacle. Amazingly, the onboard processing is done successfully by merely a Raspberry Pi 2, a credit-card sized computer with only 1Gb RAM.

Precision Landing on Moving Landing Pad

2017

In this project, a general framework for multi-robot operation is proposed and implemented. One of the proof-of-concept experiments is to have an UAV autonomously search, pursue and land on a moving AGV. The moving AGV landing pad, annotated by two QR markers, is detected by the UAV downward camera.

Non-Iterative SLAM (NI-SLAM)

2018

Non-Iterative SLAM is an innovative visual-depth-inertial SLAM method that leverages on special properties of non-circulant matrices to perform fast data-association in Fourier Domain. NI-SLAM demonstrated fast processing rate while requires little processing power.
