Mobile Robot Indoor Autonomy
in Healthcare Environments
The robot autonomously navigates a hospital hallway using SLAM-based localization and path-planning algorithms. Through its onboard sensors and cameras, it constructs a real-time map of the environment while continuously estimating its pose. The integrated Navigation Stack coordinates obstacle detection and motion control, enabling smooth traversal along corridors and adaptive maneuvering around architectural features such as walls and doorways.
Stereo vision-based measurement device for construction inspection
A measurement device for fast dimensional inspection in construction industry is designed and developed based on stereo vision. Two high-resolution cameras based on 13MP image sensor are used in this device. A variety of invariant detectors and descripters are used for image matching. The measurement error for 200 mm baseline is less than 1 mm within a range of 5 m. A prototype has been developed and tested in real construction sites.
Three-Wheeled Omnidirectional SLAM Robot
A three-wheeled omnidirectional SLAM robot is designed and developed independently. The core of the robot is a NVIDIA Jetson Nano with a Robot Operating System (ROS) wrapper—
Melodic—over the Ubuntu 18.04 OS. The SLAM algorithms are implemented in the Jetson Nano including mapping and localization.
Real-time visual SLAM robot
A real-time visual Simultaneous Localization And Mapping (SLAM) robot is built utilizing a RGB-D camera. The core of the robot is a NVIDIA Jetson TX1 with a Robot Operating System (ROS) wrapper-Indigo-over the Ubuntu 14.04 OS. The robot maps its location based on its surroundings using ORB-SLAM, with loop detection and re-localization capabilities.
Vision-based automatic cutting robot
A cutting robot for underground drainage pipe is designed to automatically reopen the lateral connection between main pipe and branch pipe after CIPP (Cured-in-Place-Pipe) installation.The robot can recognize the target cutting area by vision, and localize it by visual control and distance measurement.
Power transmission line inspection robot
This power transmission line inspection robot was designed by the team of Prof. Gongping Wu from Wuhan University. With this robot, I completed research on vision-based obstacle localization.
Remote temperature monitoring module based on ZigBee technology
A real-time temperature measurement system is built. The system measures the real-time temperature and transmits the data wirelessly to monitor computer far away by using ZigBee technology.
