Ruby On Robots

In the past few years robots have started to invade our lives, as toys or tools for around the home or at work. These robots are often much more user friendly and more importantly, hackable, than traditional industrial robots, which has lowered the barrier to writing software to control robots.

We’ll look at one particular ruby library, Artoo, a micro-framework for robotics that lets you connect to multiple different hardware devices and robots at the same time with some live demos as well.
