This golf robot uses a Microsoft Kinect camera and a neural network to line up putts

Robots that can whack a golf ball down a fairway aren't exactly new, but building one that can play the nuanced short game is a more complex problem. Researchers at Paderborn University in Germany have done just that with Golfi, a machine that uses a neural network to figure out how to line up a putt and how hard to hit the ball to get it into the hole from anywhere on the green. The robot takes a snapshot of the green with a Microsoft Kinect 3D camera and it simulates thousands of random shots taken from different positions. It takes factors like the turf's rolling resistance, the ball's weight and the starting velocity into account. Paderborn doctoral student Annika Junker told IEEE Research that training Golfi on simulated golf shots takes five minutes, compared with 30-40 hours were the team to feed data from real-life shots into the system.
