Sometimes you can find the sweetest things on the internet! Let me introduce you to Hexa: A 6-footed multipurpose robot. It doesn’t do much, but look at the potential! The six allow it to move in some very intuitive ways. It can climb over obstacles with ease. Way better than wheels.
It has an open source core, which is regularly updated and you can change it yourself, of cours.
I am seriously considering buying or build one.
