You could try using Knex instead of Lego. That way there is a good standard size of parts and everything is color coded.

Going by the link, it looks to me like it would be significantly easier with Knex

It will be easiest with the mindstorm.

why would need mindstorm? Its just simple rotation and a few gears you need for it to work. My best guess would be googling for "strandbeest" to find the page of the guy who made those. I remember him showing how one leg worked so it creates that walking motion out of a circular motion. From that base it should be easy to figure it out with legos and a few tries.

Ok i found a good picture on his side.

I think from there you should be able to figure it out.
Print out and measure it, so you can get aproximately the size differences of those parts (like 6 holes, 4 holes and so on...)

My first try still would be building this out of wood, and see it it creates the same pattern as his, or a pattern close to this.
You also need to remember that there's a time offset between legs. I think you would need at least 6 in pairs of 2 to create a good motion.

Te top left is a fixed axle, and to top right is the offset drive.
