Rebrickable

Inspired by the motorized cows created by Erik Amzallag, which can be seen in his Brickshelf gallery.  I loved these so much that I planned to build a pair, using the instructions he provided, for one of ParLUGment‘s train layouts.

Unfortunately they turned out to be a little too large for my needs – but I was determined to get this amazing idea working with cows more to scale with the standard LEGO minifig. The first step was to design a minifig scale brick built cow.

Cattle

The next step was to get their heads to turn. Since these cows are too small to contain a micro motor, the micro motor needed to be placed ‘underground’.  I built the cattle onto a 2 brick high ‘hill’.

The cows in the video below are controlled using a Mindstorms RCX and triggered with a light sensor that detects when the train passes.  Except for some changes to motor power and timing, the program used to control these cows is essentially the same as the one Erik provides in his Brickshelf gallery.
