Introduction: 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 :)
Step 1: Gather the Parts
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.
Step 2: The Crank Shaft (broken Rods)
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.
Step 3: Chassis
Step 4: Install Motor
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.
Step 5: Crank Shaft
Install as shown. make sure that each side is offset by 180 degrees.
Step 6: Crank Guards
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.
Step 7: Cell Pack
Snap these in the placement shown. Also leave the battery pack cover off since it interferes with the walking mechanism.
Step 8: Body
Step 9: Back End
its a bit of a tight fit.
Step 10: The Head
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
Step 11: Time for the Feet.
Make a mirror image of everything shown. then you're still not done until you make duplicates.
Step 12: Final Assembly
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.
Step 13: Levers!
The orange connectors on top dont go in easy you really have to force them. Make four of these.
Step 14: Levers Placement
Attach the levers onto the blue rods from step 12. The grey connectors should be facing the body and the orange should be outboard.
Step 15: FINAL Final Assembly
Snap the levers to the crank shaft and you're done!
