nick Posted October 24, 2023 Share Posted October 24, 2023 So For many years now I've been mulling around with the idea of building an AT-AT. A working one. Nothing too silly, 'bout the size of a Labrador. I've more or less figured out how to do it now, basically 4 gimbal controller boards will give me FOC Brushless motor control coupled with 3 pancake brushless motors per leg will have enough torque and precision to hold each leg as it moves, either Arduino or one of the many drone controller boards would oversee the co-ordinatoin and walking bits. I've found some good animation sequences for the walking gate too. I've got the CNC and 3D printing kit I need now too, so basically running out of excuses not to do it! Anyway, it's looking do-able, so I started looking around for decent drawings, gave up and thought I know I'll buy a kit! so I got the Bandai 144th jobbie ostensibly to reverse engineer and CAD draw all the bits. Turns out it's a really nice thing, so here it is. Somewhat hurriedly lashed together and currently residing in my office. I shall call him Keith. So surprising fact of the day, if you look up an AT-ATs frock, its nether regions are made out out of Rolls Royce Pegasus engines! probably off the nasty old Airfix 1/24th Harrier kit if I were a betting man, it was about the right time - who knew? certainly not me. If this is common knowledge, I'll get me coat, but I was quite excited about it. Anyway, heres a few cellphone snaps of the beast. It's actually a great little kit. Thanks for looking Nick 37 Link to comment Share on other sites More sharing options...
Pete in Lincs Posted October 24, 2023 Share Posted October 24, 2023 Lovely build of an iconic Sci Fi machine. Well done. The motorised version sounds exciting. You lost me with the tech stuff. So I'll just stand back and watch. Link to comment Share on other sites More sharing options...
Misrule Posted October 24, 2023 Share Posted October 24, 2023 The backside is the old Tamiya German armoured car too, and those guns are looking a bit Teutonic! Great looking machine, ready to go stomp on some plucky freedom fighters :D 1 Link to comment Share on other sites More sharing options...

Anyway, it's looking do-able And one day in the near future you will probably be able to download some open source AI code for your homemade Labrador Dog sized AT-AT and he will be able to walk around the house all on his own under his own control. 1 Link to comment Share on other sites More sharing options...

I was always going to shoot for semi-autonomous (rather than straight RC) anyway to be honest. I’ve played with DJIs drone SDK a bit and a lot of their collision avoidance/autonomy stuff should drop straight in. They have a Boston Dynamics ‘spot’ at a technology centre near me and they have taught it to pee on lamp posts. If it was mine, I would fill it with Champagne (replacing the current water) simultaneously making it both the coolest and grossest drinks waiter ever. 2 Link to comment Share on other sites More sharing options...

Funnily enough, I do have an actual excited puppy running round my hobby desk as we speak. Well 20 months but still very puppyish when it comes to excitedly running round stuff. 8 Link to comment Share on other sites More sharing options...

That's very kind, naming him after me .... or was the other Keith? 🤔 He's a good looking thing though .... unlike me! 🤣 Keith 😁 1 Link to comment Share on other sites More sharing options...
