Robotics Workshops

CHaOS will also be running several workshops on robotics, with lots of hands-on design and programming. Absolutely no experience is required, we’ll teach you all the basics and you can start making our robots do all sorts of amazing things in no time at all. We strongly recommend that you pre-book tickets for robotics workshops, as these usually run out before the day of the event.
