Giving direction control to the 10178 AT-AT walker

[efferman]

the solution for the problem is probably adding weight on the back. i put the battery pack, both motors and after the last vid dead weight in every free space in the back and it was not enough.

maybe the at-at needs a tail like a Brachiosaurus

have you any other ideas?

Do you have a 73090b "Boat Weight 2 x 6 x 2" ? They're quite heavy, and are used on the keels of Lego boats to keep them from flipping over.

[efferman]

unfortunately not

edit:

but it seems that two battery boxes fits in the back of the AT-AT. I hope this will solve the problem.

Very cool idea

[Silcantar]

What would happen if you were to use parallelogram linkages on the ankles to keep the feet and the body parallel to the ground? I don't know if that is the problem, but it might help.

good idea, but there is a little problem. this walker should look like a 10178 and with complex mechanics at the legs this is impossible.

i try it with the two battery boxes and if this doesnt work i will kill the size restrictions and construct a complete new bigger AT-AT.

edit:

the two battery boxes are not the egg of the columbus. sorry guys, for this time i will end this project. i hope the bigger one will works better.

Can you give some insight on what you had to do for the remote control? I want this set, but would really like to be able to control it with the remote.

Thanks!

First of all, I was a bit confused whether to post this topic on the Star Wars or Technic forum, but since it's about motorization, I thought I'd post it here.

I own the set 10178 Motorized Walking AT-AT. It comes with Power Functions, featuring the ability to walk forward or moonwalk backwards. I already modded it to give it remote control, with the PF set. I would like to give it direction control, but since I don't understand much about Technic, I humbly ask you for your help. I've been given two sugestions already: motorize each leg individually, or somehow create a flexible joint in the belly.

Any ideas on how to do it? What kind of parts would be involved in the task? Is that M motor enough?

I don't have the set with me to take pictures of the engines, but here is a link to a review topic so you can have some clues from the pictures.

I am also thinking of motorizing the 7675 - AT-TE, but that's another different project, first I would like to make this one come true.

Thank you all, any suggestions will be appreciated!

I'm guessing you've already disassembled this, but is it necessary for the feet to rotate along the longitudinal axis? That would keep it from dragging its feet so much, I think. Maybe that's not the solution either.

If you already have 10178 AT-AT, then to make it remote control, you'll need 8885 Power Functions Remote Control and 8884 Power Functions IR Receiver.

yes, it is disassembled, but iam working at a new version. i think rubber bands could solve this.
