Ta-dah! Josh received these awesome stackable robots from Troy and Dan for Christmas and they have been fun for the whole family. The box they came in had several examples of configurations for the robots, with varying degrees of difficulty. The top photo is an example of "advanced". The bottom photo is "expert". It is much, much harder than it looks to get these suckers to balance. Our very own Scott was the steady hand who completed these two amazing displays. Bravo!
