I was introduced to this mobile version of Boggle a few years ago. Being bad at word games, I first wrote a program that finds the words for me. It worked fine, but I was still too slow at entering the words on my phone. So I built a robot that does just that.

It consists of a Core-XY plotter that moves a stylus around, and a Raspberry Pi equipped with a camera module for taking pictures of the phone, processing them and sending commands to the plotter
