We won! The prize is a “Robotics starter pack”. Will post the contents when i get it!
Update: The pack contained an Instructables badge and some stickers, 3 packs of “sugru” silicone putty and a copy of Autodesk SketchBook Pro! Thanks Instructables!
This instructible will describe the processes required to build a system for interfacing with a robot (and the basics of building a robot) around the velleman K8055 USB interface board (availible online or at maplins) The robot is built mostly from scraps i had at home and parts from a car breakers yard the whole project cost around £50 but will be much less if you have parts at home
