I stumbled across this amazing homemade robot called Loki (named after the Norse god of mischief) last week and had to share it with you.

This four foot tall robot not only looks fantastic but seems to be highly functional, thanks to some nifty systems and programming by its creator, Dave Shinsel.

This amazing little LEGO Mindstorms robot has been programmed to solve a Sudoku puzzle and to write the missing figures in.

As you might imagine, it’s quite a complex procedure that involves scanning the digits already present and working out which squares are blank.
