For my 4th year engineering project at university, I worked with a group of engineers to create a semi-autonomous robotic arm system which accepted user input via an eye-tracker. My task in this project was to develop the object detection system to help guide the arm around the workspace. View the presentation View my code on GitHub
For my 3rd year engineering project at university, I developed a system using my Mac, an Arduino and a Kinect which could autonomously fly a small RC helicopter around a room. This took a lot of work, but worked awesomly in the end! I was able to create a system that allowed the helicopter to hover at a height of 1 metre off the floor, and centre relative to the Kinect camera.
