During the days around New Year, I have performed a finger exercise in LEGO® MINDSTORMS NXT Steampunk: the Wonderful Steam NXT. It can be built with a single NXT 2.0 set and three Rotacaster® wheels:
A Rotacaster® wheel allows for movement in two directions; they are produced and sold by the Australian Rotacaster® company and compatible to LEGO®. For the Wonderful Steam NXT, Rotacaster sponsored three of them (Thanks, Rotacaster!) , which enables it to turn on the spot.
I like these wheels a lot - they are reliable, very useful for building holonomic mobile robots (have a look at previous posts on our blog for further examples of NXT robots equipped with them) and last but not least look cool.
Update: Building instructions for the vehicle can be found on my web site.
