A Candidate for Mechanical Platform

Browsing some stuff at online shops I stumbled with Merlin Robotics Miabot , It's not the ideal thing but it can be extended thanks to some IOs to it's control board.

It's a also a little expensive for what it is, but maybe it will worth. The other option is creating a robot from scratch, what is more fun but will take more time (a LOT more) ...

I'm very tempted to buy one of those just to check it out!

A lot of designs for the extension board to run eLua and give the self-charging abilities come to my mind...
