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
Length: 9 studs
Width: 2 studs
Height: 5 studs
The normal, non-motorized, version of the cow, great for populating any pasture land you may
Since these cows are too small to contain a micromotor, the micromotor needed to be placed
The instructions provided above result in the cows standing on a 2 brick high 'hill'.
The cows 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.
