We have been developing some new tracks for Cannybots with the help of local artists. The tracks are 5ft long x 2ft wide, printed on high quality plastic banner sheets.
The Mazing (maze solving) track by @Cristina
The NASCAR style track by David Copsye
This one uses coloured marker on the tracks so the bot know which track it is on.
This looks ace - does this mean you've replaced the IR sensors with colour sensors? (or maybe as an option, I remember you mentioning them)
Yes, doesn't they look fantastic.
We have been developing an advanced version of the sensor board - http://forum.cannybots.com/t/cannybot-navigation-module/77 (Designed by the same guy, Steve Wiseman who designed BlueBrain)
But this will probably not launch until after the kicstarter campaign. Still in early prototype stage.
