: Available for postgraduate supervision

I have held multiple positions as a robotics and autonomous systems researcher and engineer in both academia and industry (Dyson, Lenovo, and Autonomous Surface Vehicles). My PhD was sponsored as part of the EU FP6 project, TAI- CHI (Tangible Acoustic Interfaces for Computer Human Interaction), which won the best exhibit prize of EU FP6 exhibition in Helsinki, Finland, in 2006.

I have very broad experience in robotics, including indoor mobile robots, humanoid robots, and outdoor unmanned autonomous surface vehicles. In particular, he has been focusing on research areas of simultaneous localisation and mapping (SLAM), computer vision, situational awareness, acoustic and tactile sensing, machine learning, swarm intelligence, robot task planning and knowledge representation.

At Dyson, as a robotics systems engineer, I have filed and published patents in the area of mobile robotics. The main project there was the Dyson 360 robot, which utilises a 360 camera for indoor localisation and mapping (Visual SLAM). I worked at Lenovo on service robotics, as a Robotic Systems Architect and Technical Leader of a team of 10 researchers and engineers with background of machine learning, computer vision, slam, cloud, and IoT. At ASV (Autonomous Surface Vehicles), I have successfully, as a core research member, delivered several projects funded by innovate UK, DSTL, and NOC/SBRI.

Before these, I had been working as a research fellow in academia for a number of EU FP6 & FP7 projects, such as TAI-CHI, IWARD (Intelligent Robot Swarm for Attendance, Recognition, Cleaning, and Delivery), ROBOSKIN (Skin-based technologies and capabilities for safe, autonomous and interactive robots), and SRS (Multi-Role Shadow Robotic System for Independent Living).

Robotics and Autonomous Systems Laboratory

I am also the operational manager of the Robotics and Autonomous Systems Laboratory. The laboratory has cutting-edge equipments for teaching and research.

One Care-o-bot 4 (advanced service robot)
Two Kuka lbr iiwa collaborative robots
Three Kuka youbot (mobile robots)
Several small turtlebots
And various advanced sensors used for robot navigation and multi-modal human robot interaction

Here is the group Github account for projects (quite empty so far) carried out in the lab.

Research Areas

Mobile Robots:

To update. Computer Vision related: Visual SLAM, Visual Servoing, Vision Odometry

One of my most valuable experience in this area is the work on the Dyson 360 Robot project:

Watch a video of the research in YouTube

Another project is the EU FP7 project, SRS, which focused on the development and prototyping of remotely-controlled, semi-autonomous robotic solutions in domestic environments to support elderly people.

SRS project (Service Robot)

Autonomous Vehicles:

As part my teaching activities (Mechatronics module), I led a team of 7 students to build a USV (Unmanned Surface Vehicle). The video below is the first trial at Cardiff Bay. We will keep developing the project in future.
