I finally finished the blueprint feature, which allows you to actually draw and share blueprints of your robots.
e.g. my Healer Drone: http://robobuilds.com/85
the creation form: http://i.imgur.com/z4n2DKF.png
I hope you guys like it and find it useful.
Please tell me, if you find any bugs or have any ideas how to improve the feature / website.
