IT WALKS - Knex Starwars AT AT

Its a four legged AT AT that walks pretty well on hard surfaces and non shag carpets. Made it over a few knex sessions and thought it would make a good first instructable. Let me know what you think :)

If you dont have the half-thick grey connectors those aren't too hard to make with a hacksaw, file, and vice. Youll also need a broken axel in the next step.

The rod in the middle needs to be 6 widths long (width meaning the thickness of a standard connector) with no end nubs. Next youll need two rods five widths long with no end nubs. The last two rods need to to be two widths long with a nub or three lengths long.

Take the crankshaft apart and use the longest broken rod (6 width) to hold the motor in place. Its supposed to float around a bit. There are no other attachments for the motor.

Install as shown. make sure that each side is offset by 180 degrees.

Snap in to keep the crankshaft from coming apart. I should have mentioned before but the build is mostly symmetrical; so do this for the other side as well.

Snap these in the placement shown. Also leave the battery pack cover off since it interferes with the walking mechanism.

its a bit of a tight fit.

Attach as shown. The blue circles are where to connect it. (ignore the broken wire on my spare motor). put the green rods in front to stop the cockpit from drooping

Make a mirror image of everything shown. then you're still not done until you make duplicates.

Line up the grey connectors on the legs with the grey connectors on the chassis then slide in a blue rod. Snap the orange connectors to the blue rod to lock it in place. Put a mirror image leg in on the left side and in front. The duplicate goes in the furthest away joint.

The orange connectors on top dont go in easy you really have to force them. Make four of these.

Attach the levers onto the blue rods from step 12. The grey connectors should be facing the body and the orange should be outboard.

Snap the levers to the crank shaft and you're done!
